Background The purpose of this study was to retrospectively evaluate the radiographic and clinical results of a small single or double low-profile plate fixation of 2.0/2.4 mm locking compression plate (LCP) in treating isolated greater tuberosity (GT) fractures of the humerus. Methods: From June 2015 to October 2022, patients who underwent LCP in treating isolated GT fractures of the humerus were included in this study. The radiological and clinical results were analyzed in 15 patients who underwent open reduction and internal fixation used 2.0/2.4 mm LCP. Results: Bone union was achieved in 14 patients (93.3%) and one failed case was treated with a 2.4 mm single LCP fixation. Radiological union was achieved within 10–20 weeks. Complications occurred in two patients (13.3%), including the reduction failure and shoulder stiffness. At the final follow-up, the average clinical scores were as follows: a visual analog scale for pain of 2.1 (range, 0–5) and a University of California, Los Angeles score of 27.2 (range, 18–31). Regarding range of motion (ROM), the average active ROMs were 142° for forward flexion (range, 120°–150°), 147.1° for abduction (range, 120°– 180°), and 59.3° for external rotation (range, 45°–80°). For internal rotation, the average was observed to reach the 10th thoracic vertebra (range, 1st lumbar vertebra–7th thoracic vertebra). Conclusions: The clinical and radiologic outcomes of treating isolated GT fracture using 2.0/2.4 mm LCP were favorable, and double low-profile plate fixation may be beneficial for sufficient fracture stability if possible. Level of evidence: Level IV, case series.
Purpose This study examined the factors affecting valgus deformities after arthroscopic reduction and internal fixation (ARIF) in lateral joint-depression tibial plateau fractures.
Materials and Methods Patients with lateral joint-depression tibial plateau fractures treated with ARIF were assessed retrospectively. The radiological evaluations included the articular depression distance (ADD) and the lateral plateau widening distance (LPWD) on preoperative and postoperative computed tomography. A postoperative valgus deformity was defined as valgus malalignment (mechanical axis ≥3°) and valgus deviation (Δmechanical axis of the operated knee from the healthy knee of ≥5°). Subgroup analyses based on a postoperative valgus deformity were performed to compare the clinical outcomes, including the range of motion, patient-reported outcomes measures, and failure and osteoarthritis progression. Furthermore, factors affecting the postoperative mechanical and Δmechanical axes were assessed.
Results Thirty-nine patients were included with a mean follow-up of 44.6 months (range, 24-106 months). Valgus malalignment and valgus deviation were observed after ARIF in 10 patients (25.6%) and five patients (12.8%), respectively. The clinical outcomes were similar in patients with and without a postoperative valgus deformity. On the other hand, lateral compartment osteoarthritis progression was significantly higher in the valgus deformity group than in the non-valgus deformity group (valgus malalignment group: 50.0% vs 6.9%, p=0.007; valgus deviation group: 60.0% vs 11.8%, p=0.032).
One patient with valgus deformity underwent realignment surgery at postoperative five years. The preoperative ADD and postoperative LPWD were significantly associated with the postoperative mechanical (both, p<0.001) and Δmechanical (ADD, p=0.001; LPWD, p=0.025) axes. Moreover, the lateral meniscectomized status during ARIF was significantly associated with the Δmechanical axis (p=0.019).
Conclusion Osteoarthritis progression was highly prevalent in patients with postoperative valgus deformity. Thus, the restoration of lateral plateau widening and articular depression and preservation of the meniscus are necessary to prevent a valgus deformity after ARIF in lateral joint-depression tibial plateau fractures.
Purpose This study compared the outcomes of minimally invasive plate osteosynthesis and antegrade intramedullary nailing for low-energy fracture of the distal femoral shaft. Materials and Methods A study was conducted on 30 patients who underwent surgery for low-energy fractures of the distal femoral shaft between January 2016 and April 2022. The study compared 15patients who underwent minimally invasive plate osteosynthesis (Group P) with 15 patients who underwent recon-type antegrade intramedullary nailing (Group N). We evaluated intraoperative blood loss, operative time, C-arm exposure time, bone density, final union status, anatomical reduction, and clinical evaluation. The complications were also examined, and statistical analysis was conducted to compare the two groups. Results The blood loss, surgery time, and C-arm time were similar in the two groups. The radiographic assessments and clinical evaluations were also similar in the two groups. The clinical results showed no difference between the groups. Group N had one case of nonunion and one case of delayed union, while Group P had one case of nonunion and one case of peri-prosthetic fracture. Conclusion Antegrade intramedullary nailing of the recon-type demonstrated comparable results to minimally invasive plate osteosynthesis. Hence, antegrade intramedullary nailing of the recon-type, which enhances stability by fixing the entire femur and providing additional fixation in the distal portion, is deemed appropriate for treating distal femoral shaft fractures.
Purpose This study examined the outcomes of additional medial locking plate fixation and autogenous bone grafting in the treatment of nonunions that occurred after initial fixation for distal femoral fractures using lateral locking plates. Materials and Methods The study involved eleven patients who initially underwent minimally invasive lateral locking plate fixation for distal femoral fractures between January 2008 and December 2020. The initial procedure was followed by additional medial locking plate fixation and autogenous bone grafting for clinically and radiographically confirmed nonunions, while leaving the stable lateral locking plate in situ. A clinical evaluation of the bone union time, knee joint range of motion, visual analog scale (VAS) pain scores, presence of postoperative complications, and functional evaluations using the lower extremity functional scale (LEFS) were performed. Results In all cases, bone union was achieved in an average of 6.1 months after the secondary surgery. The range of knee joint motion, weight-bearing ability, and VAS and LEFS scores improved at the final follow-up compared to the preoperative conditions. All patients could walk without walking assistive devices and did not experience pain at the fracture site. On the other hand, three patients complained of pain in the lateral knee joint caused by irritation by the lateral locking plate; hence, lateral hardware removal was performed. One patient complained of mild paresthesia at the anteromedial incision site.
Severe complications, such as deep infection or metal failure, were not observed. Conclusion For nonunion with stable lateral locking plates after minimally invasive lateral locking plate fixation of distal femur fractures, additional medial locking plate fixation and autogenous bone grafting, while leaving the lateral locking plate intact, can achieve successful bone union.
Purpose This study measured the physeal fracture gap on preoperative ankle computed tomography (CT) to predict the periosteal entrapment that requires an open reduction in distal tibia triplane fractures. Materials and Methods This study retrospectively reviewed patients who had undergone internal fixation for a triplane fracture from April 2004 to September 2022. The demographic data, including age,body mass index, and past medical history, were analyzed. In the radiographic evaluations, ankle CT and ankle simple radiographs, including anteroposterior (AP), lateral, and mortise views, were taken preoperatively. Postoperatively, simple ankle radiographs were obtained periodically, including AP, mortise, and lateral views. The physeal fracture gap was measured on ankle CT, and the larger gap between the coronal and sagittal view of CT was selected. The residual physeal gap <2 mm was considered an adequate reduction. Results Of 17 cases, three demonstrated successful reduction using closed reduction techniques. Periosteal entrapment was observed in 14 cases open reduction cases. In all three closed reduction cases, the physeal gap estimated on preoperative ankle CT was under 3 mm with a mean gap of 2.4±0.2 mm (range, 2.1-2.5 mm). In the remaining 14 open reduction cases, the measured physeal gap was over 3 mm, averaging 5.0±2.7 mm (range, 3.1-12.2 mm). There was a significant difference in the preoperative physeal gap between the two groups (p<0.01). Overall, good reduction was achieved in all 17 cases; the postoperative physeal gap was under 2 mm with a mean of 1.0±0.5 mm (closed reduction group, 0.5±0.2 mm; open reduction group, 1.1±0.5 mm). Conclusion Open reduction is strongly recommended for triplane fractures with a physeal fracture gap of 3 mm or more in preoperative ankle CT, suggesting the possibility of an entrapped periosteum in the fracture gap.
Purpose This study examined the difference in bone union time according to the fracture gap after minimally invasive plate osteosynthesis (MIPO) for simple distal femoral fractures in elderly patients. Materials and Methods From January 2010 to December 2019, patients aged 60 years or older who underwent surgical treatment for distal femoral fractures due to a low-energy injury were investigated retrospectively. Forty patients were enrolled in the study. The patients were divided into two groups according to the fracture gap after reduction: no more than 2 mm (Group A) and more than 2 mm (Group B) in the anteroposterior and lateral plane. The demographic, operation time, presence or absence of cerclage wiring, plate screw density, plate span ratio, plate length, bone union period, non-union, and complications were evaluated. Results No statistical differences in operation time, cerclage wiring, plate screw density, plate span ratio, and plate length were observed between the two groups, and the bone union was achieved in all patients without complication. The bone union period was 17.24±1.48 weeks in Group A and 24.53± 5.20 weeks in Group B, which was statistically significant (p<0.001). Conclusion The bone union time in treating geriatric simple distal femur fractures using the MIPO tech-nique was significantly shorter in the 2 mm or less fracture gap than in the greater than 2 mm group.
Open reduction in an AO 33-A3 class distal femur transverse and comminuted fracture is often difficult due to frequent reduction loss during surgery, leading to longer operative time and increased blood loss intra-operation. In this study, the authors report a case in which the use of an offset grid plate (OsteoMed, USA) using 2.4 mm HPS (hand plating system) eased the process of fracture reduction and achieved a stable internal fixation, ultimately leading to successful osteosynthesis. The authors experienced no need for temporary fixation devices such as K-wires or screws, which are otherwise required to stabilize the reduction. The fracture reduction was stable throughout the primary fixation of the fracture using a locking plate and screws. The authors report that the advantage of the HPS plate is fitting into the cortical contour and providing stable maintenance of fracture reduction intra-operation, which would be beneficial in certain distal femoral fracture patterns.
Purpose This study examined the one-year mortality after locking plate fixation for distal femur fractures and the risk factors related to death. Materials and Methods From July 2011 to June 2020, 128 patients who underwent locking plate fixation for distal femur fractures were analyzed retrospectively. Epidemiologic information of the patients, characteristics related to fracture and surgery, and death were investigated. The risk factors related to death were investigated using Cox analysis, and a subgroup analysis was also performed based on the age of 65 years. Results The one-year mortality rate after locking plate fixation for distal femur fractures was 3.9%, and the mortality rates in patients younger than 65 years and older than 65 years were 0% and 6.7%, respectively. There were no significant risk factors related to death in the total population. On the other hand, in patients aged 65 years or older, however, high-energy fracture and high comorbidity index increased the risk of death after surgery by 6.9-fold and 1.9-fold, respectively. Conclusion The one-year mortality rate for the total patients was 3.9%, but the mortality rate for patients over 65 years of age increased to 6.7%. High-energy fractures and high comorbidity index were risk factors related to death after surgery for distal femur fractures in patients aged 65 years or older.
Purpose Various problems have been reported with tension-band wire (TBW) fixation. With the devel-opment of anatomical plates and the improvement of fixation forces, plate fixation is currently being performed for non-comminuted, displaced, transverse olecranon fractures (Mayo Type 2A). This study compared the usefulness of the above two procedures applied in non-comminuted, displaced, transverse olecranon fractures. Materials and Methods Fifty-three patients with Mayo Type 2A were studied retrospectively. Twenty-nine patients underwent TBW fixation, while the other 24 underwent plate fixation. The averageoutpatient follow-up period was 10 months for both groups. Both groups were analyzed radiologically and clinically. The radiological assessment included the time to bone union, joint stability, and presence of traumatic osteoarthritis at the final follow-up. The clinical assessment included the operation time,range of motion of the elbow joint, Mayo Elbow Performance Score (MEPS), Disability of the Arm, Shoulder and Hand (DASH) score, and the presence of postoperative complications. Results Both groups showed stable elbow joints, proper union of fractures, and no traumatic osteo-arthritis at the final follow-up. The range of motion for the TBW fixation group was 142° (range, 3°-145°), while that of the plate fixation group was 135° (range, 4°-139°) at the final follow-up (p=0.219). The MEPS was 98.2 and 97.7 for the TBW fixation and plate fixation groups, respectively (p=0.675). The DASH score was 10.7 and 13.9 for the TBW fixation and plate fixation groups, respectively. Both groups showed excellent results, and the differences were not statistically significant (p=0.289). Conclusion TBW fixation and plate fixation were compared in non-comminuted, displaced, transverse olecranon fractures, and good results were obtained without significant differences between the two groups. Hence, surgeons should choose a technique they are more confident with and can be applied more efficiently.
Purpose The purpose of this study was to evaluate and compare the clinical and radiological outcomes between locking plates and non-locking plates using posterior anti-glide plating for supination external rotation type lateral malleolar fractures. Materials and Methods A total of 50 patients who underwent internal fixation of posterior anti-glide plating due to lateral malleolar fractures, classified as supination-external rotation (SER) as per the Lauge-Hansen classification system, at our hospital from January 2017 to November 2018 were retro-spectively evaluated. Patients were divided into two groups: 1/3 semi-tubular locking plate (24 patients) and 1/3 semi-tubular non-locking plate (26 patients). A radiographic assessment was performed after surgery to evaluate the time of bone union. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot functional score was measured after the surgery to evaluate the clinical outcomes. Results The two groups showed similar distributions in sex, age, height, body mass index, fracture pattern, and mean follow-up period. Complete bone union was obtained in all cases and the mean bone union time was 13.00±3.38 weeks in Group 1 and 12.92±3.26 weeks in Group 2 (p=0.87). The mean AOFAS score at 24 weeks was 95.66±2.86 in Group 1 and 95.84±2.79 in Group 2 (p=0.82). The mean AOFAS score at 48 weeks was 97.25±3.54 in Group 1 and 96.57±3.07 in Group 2 (p=0.47). Two cases of complications were observed in the non-locking plate group. Conclusion For the treatment of Lauge-Hansen SER type lateral malleolar fracture, internal fixation us-ing locking 1/3 semi-tubular plate and non-locking 1/3 semi-tubular plate are both favorable fixation methods.
Purpose We compared the radiological and clinical results of fixation for distal femoral fracture (DFF) using a locking compression plate (LCP) or a retrograde intramedullary nail (RIN). Materials and Methods From October 2003 to February 2020, 52 cases of DFF with a minimum 1-year follow-up (with a mean follow-up of 19.1 months) were included: 31 were treated with LCP and 21 with RIN. The operation time, blood loss, and hospitalization period were compared, and the incidence of postoperative nonunion, malunion, delayed union and metal failure and other post-operative complications were evaluated and compared. Results There was no significant difference in the operating time between the two groups, but the mean blood loss was significantly higher in the LCP group (LCP 683.5 ml vs RIN; 134.9 ml; p=0.015). In 49 out of 52 cases, bone union was achieved without additional surgery in an average of 6.8 months, and a complete union was achieved after additional surgery in three cases of nonunion (LCP 2 cases vs RIN 1 case; p=0.065). One case of malunion and superficial infection was confirmed in each group. Conclusion Internal fixation using LCP and RIN give good outcomes with a low complication rate and can therefore be considered useful surgical treatments for DFF.
Purpose There are no standard surgical treatments for open distal radius fractures (DRFs), and the fracture fixator is chosen by the surgeon’s own experience. This study compared the outcomes of open reduction and volar locking plating (OR VLP) between closed and open AO-OTA type C3 DRFs.
Materials and Methods: Patient data were retrospectively collected between January 2010 and December 2018. Only patients aged >18 years with AO-OTA C3 DRFs were included. After further exclusion, the patients with DRFs were divided into two groups: 13 patients with open DRFs in Group 1 and 203 patients with closed DRFs in Group 2. Data on the patient characteristics and treatment-related factors were further investigated. For the radiological evaluation, the radial height, volar height, and volar titling were measured based on the final plain radiography, and the union time was measured. The wrist range of motion (ROM), pain visual analogue scale score, and modified Mayo wrist score for function were measured at the final outpatient follow-up. Finally, the complications associated with OR VLP fixa-tion were investigated.
Results: In the demographic comparison, the patients with open fractures were older (mean age, 62years) than those with closed fractures (mean age, 57 years), without a statistically significant differ-ence. The patients with open DRFs had longer antibiotic therapy and hospital stay durations. Although they presented a higher radial inclination, with statistical significance, the clinical implication was low with a mean difference of 3°. No significant differences were observed for the remaining radiological parameters, wrist ROM, and functional scores. An open DRF did not increase the complication rates,including deep infection.
Conclusion: Depending on the expertise of the operating surgeon, the primary OR VLP fixation in open intra-articular comminuted DRF did not increase the incidence of deep infections and yielded similar outcomes to a closed intra-articular comminuted DRF.
Purpose This study examined the clinical outcomes after the treatment of a tibia segmental fracture with intramedullary nailing (IM nailing) and minimal invasive plate osteosynthesis (MIPO). Materials and Methods From July 2012 to December 2017, 14 out of 17 cases from a treatment cohort of 32 cases of AO type 42 C2 tibia segmental fractures with IM nailing and MIPO were studied retrospectively. Periodic radiographs were used to evaluate the presence of union, union time, and radiographic evaluation of bony union (varus-valgus deformity, anteroposterior angular deformity, shortening). To evaluate the postoperative clinical function, modified Rasmussen’s system was used for proximal fractures, and the American Orthopaedic Foot and Ankle Society functional score was used for distal fractures. Results Bony union was achieved in all 14 cases, and the average union time was 26 weeks. In one case of soil contamination, there were no other complications other than simple debridement after a soft tissue infection. The mean varus was two degrees; the mean anteroposterior angular deformity was three degrees of anterior oblique; the mean length shortening was 5 mm (2-9 mm). The mean functional score of the knee joint with the Modified Rasmussen’s system measured for the postoperative clinical function was relatively good (excellent 9, good 4, fair 1, and poor 0). The results of the Molander and Olerud Functional scores of the ankle joints were also good (excellent 8, good 3, fair 2, poor 0). Conclusion The treatment of tibia segmental fractures with IM nailing and MIPO can effectively reduce the gap of fracture sites. Hence, it is possible to increase the bony union probability and obtain relatively satisfactory alignment. Overall, the treatment of tibia segmental fractures with IM nailing and minimally invasive plate osteosynthesis appears to be a useful treatment, considering the preservation of the soft tissue and the alignment of the tibia.
Purpose This study compared minimally invasive plate osteosynthesis (MIPO) using a single small skin incision and conventional open volar locking plate fixation (OP) for distal radius fracture to identify outcome difference. Materials and Methods Forty-three patients who underwent MIPO using a single small skin incision or OP for distal radius fractures were evaluated retrospectively. Of the patients, 21 were treated with MIPO using a single small skin incision and 22 with the OP method through the conventional volar approach. The postoperative radiographic results and clinical outcomes at the final follow-up in each group were compared. Results All patients achieved bone union in the MIPO and OP groups. No significant differences in the bone union time, alignment, range of motion, QuickDASH, or pain score were observed. On the other hand, the size of the incision was significant: 23 mm in the MIPO group and 55 mm in the OP group (p<0.001). Conclusion MIPO technique using a single small incision showed similar satisfactory radiographic and functional outcomes compared to conventional OP for distal radius fractures. The MIPO technique using a single small incision offered advantages, including cosmetic benefits and minimal soft tissue damage, is recommended, particularly in young women and high functional demand patients.
PURPOSE The purpose of this study was to compare the clinical and radiological outcomes of locking compression plate (LCP)-screw fixation and tension band wiring (TBW) fixation in isolated lateral malleolar fractures. MATERIALS AND METHODS From May 2016 to August 2018, 52 patients with isolated lateral malleolar fracture were retrospectively reviewed. They were divided into 30 cases of the LCP fixation group (Group I) and 22 cases of the TBW fixation group (Group II). The clinical and radiological results of those groups were compared. Pearson chi-square tests and independent t-tests were used in the statistical analysis. RESULTS The mean length of the surgical incision was 8.3 cm in Group I and 4.9 cm in Group II. Radiological union was obtained at a mean of 8.4 weeks in both groups. The mean American Orthopaedic Foot and Ankle Society score was 90 (range, 85–97) and 92 (range, 85–100) in Groups I and II, respectively, at the last follow up. CONCLUSION Both the LCP-screw and TBW techniques revealed excellent results in isolated lateral malleolar fractures. The tension band technique may be a fine alternative method of fixation in the treatment of isolated lateral malleolar fracture.
PURPOSE This study investigated the clinical and radiological outcomes of patients undergoing provisional fixation in conjunction with locking plate fixation. Miniplates were used as the reduction plates for the surgical treatment of severe comminuted metadiaphyseal fractures with an intra-articular fracture of the distal radius. MATERIALS AND METHODS The radial length, radial inclination, volar tilt, and radial intra-articular step-off were measured preoperatively, postoperatively, and at one year after surgery in 12 patients (eight males, four females, mean age 55.4 years old). The patients underwent volar locking plate fixation with miniplate as a reduction plate for severe comminuted metadiaphyseal fractures with an intra-articular fracture of the distal radius. Clinical evaluations were conducted using the modified Mayo wrist score (MMWS). RESULTS Bone union was achieved in all cases. The mean MMWS was 81.8 points, including two excellent, three good, and seven fair cases. Radiological improvements were observed in the average radial length (preoperative, 6.4 mm; postoperative, 11.8 mm), average radial inclination (10.2° to 22.4°), average volar tilt (−4.5° to 10.6°), and average radial intra-articular step-off (4.8–0.8 mm) (all, p<0.05). Radiographic measurements obtained immediately after surgery and at the final follow-up revealed insignificant decreases in radial length (0.6 mm), radial inclination (0.4°), and volar tilt (0.9°) (all, p>0.05). CONCLUSION Miniplate fixation can be an effective treatment option as a reduction plate for the treatment of distal radial fractures, which is challenging to reduce and maintain due to severely comminuted metadiaphysis fractures with the intra-articular fracture.
PURPOSE Many international journals have published studies on the results of distal femoral fractures in elderly people, but only a few studies have been conducted on the Korean population. The aim of this study was to determine the factors that are associated with the outcomes and prognosis of fixation of distal femur fractures using the minimally invasive plate osteosynthesis (MIPO) technique in elderly patients (age≥60) and to determine the risk factors related witht he occurrence of nonunion. MATERIALS AND METHODS This study is a retrospective study. From January 2008 to June 2018, distal femur fracture (AO/OTA 33) patients who underwent surgical treatment (MIPO) were analyzed. A total of 52 patients were included in the study after removing 121 patients that met with the exclusion criteria. Medical records, including surgical records, were reviewed to evaluate the patients' underlying disease, bone mineral density, the number of days delayed from surgery, complications and mortality. In addition, follow-up radiographs were used to determine bone union, delayed union and nonunion. RESULTS The average time to achieve bone union was 19.95 weeks, the rate of nonunion was 20.0% (10/50) and the overall mortality was 3.8% (2/52). There were no significant differences in the clinical and radiological results of those patients with or without periprosthetic fracture. On the univariate analysis, which compared the union group vs. the nonunion group, no factors were identified as significant risk factors for nonunion. On the multiple logistic regression analysis, medical history of cancer was identified as a significant risk factor for nonunion (p=0.045). CONCLUSION The rate of nonunion is high in the Korean population of elderly people suffering from distal femur fracture, but the mortality rate appears to be low. A medical history of cancer is a significant risk factor for nonunion. Further prospective studies are required to determine other associated factors.

Atypical fractures associated with prolonged bisphosphonate (BP) therapy rarely occur outside the femur, and the diagnostic criteria, appropriate treatment principles, and fixation methods for atypical ulnar fractures have not been established. The authors experienced the use of internal fixation with a metal plate and a new internal fixation method with an intramedullary nail in the treatment of an atypical ulnar fracture in a patient who had been on BP therapy for 10 to 20 years. This paper reports findings along with a review of the relevant literature.

PURPOSE This study analyzed the results of the midclavicle fracture treatment using the minimally invasive percutaneous plate osteosynthesis (MIPO) technique in a retrospective manner. MATERIALS AND METHODS Between March 2013 and March 2017, this study analyzed 40 patients who received MIPO surgery. Excluding 1 patient who underwent surgery on another body part injury, and 4 patients who were lost to follow-up over 1 year, 40 patients were analyzed for their operation time, bone union, functional American Shoulder and Elbow Surgeons score, scar lengths, pain relief (visual analogue scale), and complications. RESULTS All patients over a 1 year of follow-up achieved bone union, and American Shoulder and Elbow Surgeons score 97.6 (94–100) on their shoulder functional scores. Their average operation time was 42.7 minutes, and the average scar length was 6.1 cm. Eighteen patients successfully received metal removal using the previous scar without additional incision. The clavicle length was similar in the normal and operated group. CONCLUSION Despite its small sample size, clavicle fixation using the MIPO technique can be considered an effective treatment because of its limited number of complications, such as nonunion and rotational angulations.

PURPOSE This study examined whether any fracture pattern shown in computed tomography (CT) scan is associated with the presence of lateral meniscus (LM) injury in a tibia plateau fracture. MATERIALS AND METHODS Fifty-three tibia plateau fractures with both preoperative CT and magnetic resonance imagings (MRI) available were reviewed. The patient demographics, including age, sex, body mass index, and energy level of injury were recorded. The fracture type according to the Schatzker classification, patterns including the lateral plateau depression (LPD), lateral plateau widening (LPW), fracture fragment location, and the number of columns involved were assessed from the CT scans. The presence of a LM injury was determined from the MRI. The differences in the factors between the patients with (Group 1) and without (Group 2) LM injuries were compared and the correlation between the factors and the presence of LM injury was analyzed. RESULTS The LM was injured in 23 cases (Group 1, 43.4%) and intact in 30 cases (Group 2, 56.6%). The LPD in Group 1 (average, 8.2 mm; range, 3.0–20.0 mm) and Group 2 (average, 3.8 mm; range, 1.4–12.1 mm) was significantly different (p < 0.001). The difference in LPW of Group 1 (average, 6.9 mm; range, 1.2–15.3 mm) and Group 2 (average, 4.8 mm; range, 1.4–9.4 mm) was not significant (p=0.097). The other fracture patterns or demographics were similar between in the two groups. Regression analysis revealed that an increased LPD (p=0.003, odds ratio [OR]=2.12) and LPW (p=0.048, OR=1.23) were significantly related to the presence of a LM tear. CONCLUSION LPD and LPW measured from the CT scans were associated with an increased risk of concomitant LM injury in tibia plateau fractures. If such fracture patterns exist, concomitant LM injury should be considered and an MRI may be beneficial for an accurate diagnosis and effective treatment.

PURPOSE The aims of this study were to evaluate risk factors for knee stiffness after the fixation of distal femoral fractures, and to analyze the clinical and radiologic outcomes. MATERIALS AND METHODS This is a retrospective case control study of 104 consecutive patients who have a distal femoral fracture and were treated with a submuscular locking plate. The case group comprised of patients with 12-month postoperative range of motion (ROM) ≤90° or a history of manipulation under anesthesia. The case group was compared with the control group of patients with a 12-month postoperative ROM >90°. The possible risk factors were evaluated by univariate and logistic regression analysis. The postoperative ROM and Knee Society clinical rating system was evaluated for the clinical assessment and the distal femoral angle on a whole-extremity scanogram was measured for radiologic assessments. RESULTS Fifty-four patients were included in the study (14 in the case group, 40 in the control group). Univariate analysis showed that comminuted fracture, intra-articular fracture, open fracture, temporary external fixation, severe osteoarthritis, and prolonged immobilization placed patients at an increased risk for knee stiffness. On the other hand, multivariate logistic regression showed that an extensor mechanism injury was the only significant predictor (p=0.001; odds ratio, 42.0; 95% confidence interval, 5.0–350.7). The ROM and Knee Society score were significantly lower in the case group; however, the coronal alignment was similar in the case and control group. CONCLUSION Various factors that delay postoperative knee motion place patients at increased risk of knee stiffness. Understanding these risk factors may help surgeons prevent postoperative knee stiffness after distal femoral fractures. In particular, extensor mechanism injury, such as patella fracture or open quadriceps injury, was found to be an independent predictable factor associated with knee stiffness.

PURPOSE This study compared the radiological and clinical results of minimally invasive plate osteosynthesis (MIPO) and intramedullary nailing (IMN) of distal tibial fractures, which were classified as the simple intra-articular group and extra-articular group. MATERIALS AND METHODS Fifty patients with distal tibial fractures, who could be followed-up more than 12 months, were evaluated. Group A consisted of 19 patients treated with MIPO and group B consisted of 31 patients treated with IMN. The results of each group were analyzed by radiological and clinical assessments. RESULTS The mean operation times in groups A and B were 72.4 minutes and 65.7 minutes, respectively. The mean bone union times in groups A and B were 16.4 weeks and 15.7 weeks, respectively. The bone union rate in groups A and B were 100% and 93%, respectively. The ranges of ankle motion were similar in the two groups at the last follow-up. The mean American Orthopaedic Foot and Ankle Society score was similar: 90.1 in group A and 90.5 in group B. The radiological and clinical results were similar in the intra and extra-articular groups. In groups A and B, two cases of posterior angulation and five cases of valgus deformity of more than 5° were encountered. CONCLUSION Both MIPO and IMN achieved satisfactory results in extra-articular AO type A and simple articular extension type C1 and C2 distal tibia fractures.

PURPOSE The purpose of this study was to evaluate the radiological and clinical results of plate fixation and external fixation with additional devices for treating distal radius fracture in AO type C subtypes, and propose a treatment method according to the subtypes. MATERIALS AND METHODS Two hundred and one AO type C distal radius fracture patients were retrospectively reviewed. Eighty-five patients in group 1 were treated with volar or dorsal plate, and 116 patients in group 2, were treated with external fixation with additional fixation devices. Clinical (range of mtion, Green and O'Brien's score) and radiological outcomes were evaluated. RESULTS At the 12-month follow-up, group 1 showed flexion of 64.4°, extension of 68.3°, ulnar deviation of 30.6°, radial deviation of 20.8°, supination of 76.1°, and pronation of 79.4° in average; group 2 showed flexion of 60.5°, extension of 66.9°, ulnar deviation of 25.5°, radial deviation of 18.6°, supination of 73.5°, and pronation of 75.0° in average. The mean Green and O'Brien score was 92.2 in group 1 and 88.6 in group 2. The radial height of group 1 and group 2 was 11.6/11.4 mm; radial inclination was 23.2°/22.5°; volar tilt was 11.6°/8.7°; and the ulnar displacement was 1.27/0.93 mm. CONCLUSION Judicious surgical techniques during device application and tips for postoperative management during external fixation can produce similar clinical results compared with internal fixation patients.

PURPOSE Twenty early surgical management cases of distal humerus type-C fractures were analyzed. MATERIALS AND METHODS This study analyzed 20 early patients, who received surgical management of distal humerus type-C fractures, and could be followed-ups for more than one year between March of 2013 and May of 2015. The operative time, bone union time, and elbow range of motion were analyzed. The Mayo's functional score was used to evaluate their postoperative function. The primary and secondary complications of each patient immediately after each of their surgery were also reviewed. RESULTS All patient groups achieved bone union within an average period of 16.4 weeks. Based on the Mayo functional score, 6, 10, and 4 patients scored excellent, good, and fair, respectively. The average range of motion was a flexion contracture of 14.5° with a follow-up improvement averaging 120.7°. Six patients received nine revision operations due to major and minor complications. Two patients received revision fixation from an inadequate fixating power, and another patient received an ulnar nerve transposition. Other complications included olecranon osteotomy site displacement, superficial operational site infection, and pin loosening. CONCLUSION Distal humerus fractures of the AO-C type can cause a range of complications and has a very high rate of revision due to its difficult nature of surgical manageability. Therefore, it is imperative for a surgeon to expect various complications beforehand and a careful approach to their postoperative rehabilitation is essential.
PURPOSE We evaluated the usefulness of an additional, 2.7 mm mini-locking plate for tibial pilon fractures. MATERIALS AND METHODS We studied 21 patients (14 males and 7 females), who were treated with a 2.7 mm mini-locking plate via the anterolateral approach for tibial pilon fractures between September 2012 and April 2014. The mean age was 43.85 years, and the mean follow-up period was 16.6 months. The radiologic outcomes were graded by the Burwell and Charnley modified system and clinical outcomes were evaluated by the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score and visual analogue scale (VAS) score. RESULTS The mean union period was 14.3 weeks. At the final follow-up, radiologic results showed 16 excellent results, 4 fair results, and 1 poor result. The average VAS was 3.4 points; the average AOFAS score was 81.8 points. During the follow-up period, there were three cases of posttraumatic osteoarthritis and one case of superficial skin infection. CONCLUSION Additional anterolateral, 2.7 mm mini-locking plate may be a good treatment method to manage tibial pilon fractures.
PURPOSE The purpose of our study is to compare the radiographic and clinical outcomes with respect to acromioclavicular (AC) joint dislocation depending on the surgical method: Hook plate (HP) versus TightRope (TR). MATERIALS AND METHODS Between May 2009 and May 2012, 51 patients with Rockwood type III-V lesions received clinical and radiographic follow-up. Patients were divided into two groups according to the surgical methods (HP: n=32; TR: n=19). Radiological follow-up included comparative coracoclavicular distance (CCD) measurements as a percentage of the uninjured shoulder. For clinical follow-up, a standardized functional shoulder assessment with the Constant score, University of California at Los Angeles (UCLA) score, and Korea shoulder score (KSS) were carried out. RESULTS Comparing the functional results, no differences were observed between the two groups (Constant score: HP, 78.5; TP, 81.4; UCLA score: HP, 29.2; TP, 29.9; KSS: HP, 79.2; TP, 80.7). Time to restoration of the range of motion (ROM) above shoulder level was longer in the HP group than in the TR group. However, the ROM at 1 year postoperation and final follow-up revealed similar results between the two groups. The AC joints were well reduced in both groups, the CCD increased to 44.7% in the HP group and to 76.5% in the TR group at the final follow-up; however, no one was significantly superior to the others. Furthermore, there were 8 cases (25.0%) and 5 cases (26.3%) of AC joint arthritis in the HP group and TR group, respectively. However, the observed AC joint arthritis has a poor correlation between clinical symptom and radiological results in both groups. CONCLUSION Both HP and TR fixation could be a recommendable treatment option in acute unstable AC joint dislocation. Both groups showed excellent radiologic and functional results at the final visit. Moreover, there was no significant difference in statistics, except for the time to restoration of ROM above shoulder level.

Generally, lateral plating is used for a comminuted fracture of the distal femur. However, in some cases, it has been shown that using a medial plate is necessary to achieve better outcome. Nevertheless, there are no available anatomical plates that fit either the distal medial femoral condyle or fracture fixation, except for the relatively short plate developed for distal femoral osteotomy. We found that locking compression plate-proximal lateral tibia (LCP-PLT) fits anatomically well for the contour of the ipsilateral medial femoral condyle. Moreover, LCP-PLT has less risk of breaking the thread holes since it rarely needs to be bent. We report a plastic bone model study and two cases of distal femoral fractures fixed with medial plating using LCP-PLT.

PURPOSE The purpose of this study is to evaluate the postoperative outcomes of elderly patients with stable 2-part intertrochanteric femur fractures surgically treated using dynamic hip screw with 2-hole side plate. MATERIALS AND METHODS From February 2008 to January 2014, 50 patients older than the age of 65 years, who had been followed-up for more than 6 months after the operation at The Catholic University of Korea, Bucheon St. Mary's Hospital were enrolled. A clinical evaluation of the skin incision length, operating time, and ambulatory status, using Clawson's Ambulation Capacity Classification, was performed, and a radiologic evaluation of Fogagnolo reduction quality, tip-apex distance (TAD), Cleveland index, sliding extent of lag screws, time duration till bony union, and complications was also done. RESULTS The mean skin incision length was 9.8 cm (range, 8-13 cm), the mean operating time was 41.4 minutes (range, 30-60 minutes), and 32 patients recovered their ambulatory function. Forty-eight patients gained bony union, and the time lapsed till union was average 10.6 weeks (range, 8-16 weeks). The evaluation of postoperative radiologic images showed the following reduction statuses by the Fogagnolo classification: 46 cases of "Good", 3 cases of "Acceptable," and 1 case of "Poor." Moreover, the mean TAD was 18.9 mm (range, 9.0-24.9 mm). While 45 cases fit into the zone 5 of the Cleveland index, other 3 were within zone 8 and the other 2 were within zone 6. The mean sliding length of the lag screws were 4.9 mm (range, 0.1-19.4 mm). There were a case of nonunion and a case of periprosthetic infection with nonunion as complications. CONCLUSION Using dynamic hip screws with 2-hole side plate for stable 2-part intertrochanteric femur fractures in elderly patients showed satisfactory results with respect to the recovery of ambulatory functions and bony union.
Some proximal humeral fractures in elderly patients are accompanied by medial metaphyseal comminution and quality of the bone is so poor that head preserving osteosynthesis seems to be amenable. In cases of medial metaphyseal comminution, lateral locking compression plate (LCP) fixation also has a tendency to become a matter of screw cut out or loss of fixation. The author reports on successful treatment of two osteoporotic proximal humeral fractures combined with medial meta-physeal comminution, with application of additional direct medial supporting plate fixation. Medial plate fixations were added when the fractures were still unstable after the conventional lateral LCP fixation and anterior circumflex humeral arteries had been ruptured before. The fixations were stable enough to start exercise immediately after surgery. The inclinations of the humeral neck were not changed until the last follow-up and clinical results were satisfactory without humeral head osteonecrosis which was a concern.

Hook plate fixation is a treatment method for the displaced distal clavicle fracture with favorable results regarding bone union and shoulder function, however possible complications include impingement syndromes, subacrormial erosions, acromial fractures, and periprosthetic fractures. In this report, we observed 3 cases of periprosthetic fracture after hook plate fixation. All cases of periprosthetic fractures were initiated at the medial end screw holes. The causes of these periprosthetic fractures appeared to be the off centered fixation of medial end screws near the anterior or posterior cortex which were specific during operations with hook plates with more than 6 holes and the increased stress on the medial end screw by over-reduced or inferiorly reduced position of the distal end of the clavicle by the hook plate.
