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 radiological outcomes of fixation using an anatomical quadrilateral surface plate with those using a traditional pelvic reconstruction plate for fractures involving the quadrilateral surface or superomedial wall of the acetabulum. Materials and Methods From 2015 to 2022, 47 patients who met the inclusion and exclusion criteria were analyzed retrospectively. Internal fixation of an acetabular fracture was achieved with a pelvic reconstruction plate (n=28) or an anatomical quadrilateral surface plate (n=19). The ability to achieve immediate postoperative anatomical reduction and the long-term outcomes were assessed by confirming the arthritic changes. Immediate postoperative reduction quality and long-term radiological outcomes for post-traumatic arthritis were assessed using the Matta scoring system on standard radiographs. Results The assessment of immediate postoperative reduction in the pelvic reconstruction plate group was satisfactory in 16 patients (57.1%) and unsatisfactory in 12 patients (42.9%). In the anatomical quadrilateral surface plate group, the results were satisfactory in 16 patients (84.2%) and unsatisfactory in 3 patients (15.8%). When evaluating over an extended follow-up period in the pelvic reconstruction plate group, 19 patients (67.9%) demonstrated satisfactory, while 9 patients (32.1%) had unsatisfactory outcomes. In the anatomical quadrilateral surface plate group, 12 patients (63.2%) achieved satisfactory, and 7 patients (36.8%) had unsatisfactory outcomes. The immediate postoperative reduction quality was superior in the anatomical quadrilateral surface plate group (p=0.03). Comparing longterm results, the anatomical quadrilateral surface plate group did not have statistically more favorable outcomes (p=0.49). Conclusion In this study, the anatomical quadrilateral surface plate achieved sufficiently good radiological results without significant difference from the existing pelvic reconstruction plate. It was concluded that it is a useful option that can replace the existing metal plate in the selection of surgery for acetabular 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 Internal fixation after a femoral neck fracture (FNF) is one of the conventional treatment options for the young and active elderly patients. However, fixation failure of internal fixation is a probable complication. The treatment of fixation failure after a primary internal fixation of the FNF remains a challenge. Materials and Methods Between July 2002 and March 2017, 83 patients who underwent internal fixation after FNF were retrospectively analyzed. Radiological assessments, including Pauwels’ angle, fracture level, reduction quality, and bone union, were measured, preoperatively and postoperatively.
Moreover, intraoperative variables such as time to surgery, surgical time, and estimated blood loss were also evaluated. Results The patients were divided into the fixation failure and the non-failure groups. Among the 83 patients, 17 cases (20.5%) of fixation failure after the primary internal fixation of the FNF were identi-fied. When comparing the two groups according to the radiographic data, Pauwels’ angle and the reduction quality based on Garden’s angle showed significant differences (p<0.001). Moreover, when comparing the intraoperative variables, unlike the surgical time and estimated blood loss, significant differences were noted in the time interval from injury to surgery and specifically in whether the surgery was performed within 12 hours after injury (p<0.001). Conclusion Pauwels’ angle, reduction quality, and time to surgery are the major factors that can predict the possibility of internal fixation failure of the FNF. Early and accurate anatomical reduction is needed to decrease complications after the internal fixation of the FNF.
According to the Letournel classification, a transverse fracture is the only elementary fracture pattern that breaks both the anterior and posterior border of the innominate bone. A transverse acetabular fracture separates the innominate bone into two segments: the iliac segment and the ischiopubic segment. Therefore, minimally displaced transverse fractures can be stabilized by purchasing both segments with a large-diameter single screw. Although it is not a stable internal fixation construct compared with plates and screws, it provides sufficient stability to promote early mobilization and early weight-bearing while minimizing the risk of secondary displacement and preventing secondary complications associated with prolonged bed rest and immobilization. The authors successfully treated a case of minimally displaced transverse acetabular fracture with percutaneous column fixation using a retrograde fashion of a single anterior column screw. This report discusses the case with a literature review and deliberates the usefulness of the procedure.
The incidence of fragility fractures of the pelvis (FFP) has increased significantly due to the aging popu-lation and improved diagnostic modalities. The evaluation and treatment of these patients differ from that of high-energy pelvic ring injuries typically seen in younger patients. Therefore, it is important to classify the FFP by patterns of the classification system to standardize optimal treatment criteria and appropriate treatment strategy. However, some cases are not classifiable according to the FFP classifi-cation. A newly proposed classification that can be verified by comparing existing FFP classifications is needed to overcome the weak points. Non-operative treatment is usually considered first and should focus on early mobilization. Operative fixation should focus on stabilizing the minimally invasive pelvic ring than the reduction of fractures to facilitate early mobilization and avoid complications that can arise from comorbidities associated with immobility.
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 To identify the biomechanical features for clinical applications through a computational simulation of the fixation of the Femoral Neck System (FNS) with additional cannulated screws for a Pauwels type III femoral neck fractures. Materials and Methods Thirty cadaveric femurs underwent computed tomography, and the images were transferred to the Mimics ® program, resulting in three-dimensional proximal femur models. A three-dimensional scan of the FNS and 6.5 mm and 7.0 mm cannulated screws was performed to enable computerized virtual fixation of FNS with additional cannulated screws for unstable femoral neck fractures. Furthermore, the cannulated screw used for additional fixation was modeled and used as a cylinder within the Ansys program. The biomechanical characteristics of these models were investigated by applying a physiological load virtually. Results The maximum von Mises stress value at bone was 380.14 MPa in FNS and 297.87 MPa in FNS+7.0 mm full-thread cannulated screw. The maximum von Mises stress value at FNS was 786.83 MPa in FNS and 435.62 MPa in FNS+7.0 mm full-thread cannulated screw. The FNS group showed the highest maximum von Mises stress values at bone and FNS. For total deformation, the maximum deformation value was 10.0420 mm in FNS and 9.2769 mm in FNS+7.0 mm full-thread cannulated screws. The FNS group represented the highest maximum deformation compared to the other groups. Conclusion Considering the anatomical spatiality and biomechanical characteristics of the FNS in unstable femoral neck fractures, when one 7.0 mm full thread cannulated screw was also fixed to the anterosuperior portion of the FNS, significant biomechanical stability was demonstrated.
This review focused on the research published to date on the treatment of phalangeal fractures according to the anatomical location of the finger bones, excluding the thumb. In many finger fracture cases, conservative treatment should be prioritized over surgical treatment. The three determinants of surgical treatment are the presence of an intra-articular fracture, the stability of the fracture itself, and the degree of damage to the surrounding soft tissues. Surgical treatment is recommended when bone fragments of 3 mm or more and distal phalanx subluxation are present in the bony mallet finger, and the main surgical treatment is closed reduction and extension block pin fixation. It is essential to pay attention to rotational deformation asf ractures occur proximally. Since intra-articular fractures can cause stiffness and arthritis in the future, a computed tomography scan is recommended to confirm the fracture pattern. These fractures require anatomical reduction of the bone fragments within the joint, and the instability of the joint itself must be corrected. There are no superior surgical treatment methods. It is therefore advantageous for the surgeon to select a surgical method that he is familiar with and confident of performing, considering the fracture itself and various patient-related clinical factors. Nonunion is rare as a complication of a finger fracture, and finger stiffness is the most common complication. Ensuring rapid joint movement as soon as possible can reduce finger stiffness.
Purpose Trochanteric fixation nail advanced (TFNA) was modified to compensate for the shortcomings of proximal femoral nail antirotation-II (PFNA-II). The clinical and radiological outcomes of surgeries us-ing the PFNA-II and TFNA for femoral intertrochanteric fractures were compared. Materials and Methods Eighty-two patients who underwent surgeries using PFNA-II or TFNA were analyzed. Only those who were followed up for more than a year were enrolled. Bone union, shortening of the femoral neck, and the tip–apex distance of the intramedullary nail were compared in the radiological findings. Clinical outcomes, including the frequency of complications and gait ability (Koval score), were also assessed. Results The mean follow-up periods were 22 and 19 months for the PFNA-II and TFNA groups, re-spectively. In the PFNA-II group, two cases of femoral head cut-out and one case of varus collapse were observed. In the TFNA group, only one case of femoral head cut-out was observed; however, there was no significant difference in the frequency of complications between the two groups (p=0.37). Ad-ditionally, both the shortening of the femoral neck and the decrease in gait ability after surgery showed relative improvement in the TFNA group compared to the PFNA-II group; however, there was no sig-nificant difference between the two groups. Conclusion The use of both TFNA and PFNA-II was associated with satisfactory outcomes. In patients who underwent surgeries using TFNA, the recovery of gait ability, frequency of complications, and short-ening of the femoral neck were not significantly different from PFNA-II, suggesting that both are suitable instrument choices for intertrochanteric fracture treatment. However, the clinical significance must be further assessed using a larger group of patients over a longer follow-up period in future studies.

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.
There have been major advances in the treatment of distal radius fractures over the past 20 years. Specifically, the development of the volar locking plate in 2001 and the subsequent improvements in its design and performance have enabled the treatment of distal radius fractures that were previously considered difficult to treat. The volar plate is used for fractures and shows good results with anatomical reduction and firm fixation. However, when trying to apply it to more complex fractures, there are still difficulties related to the unique anatomical structure of the distal radius, and there are also several factors that can impair joint function and cause pain after surgery. In this review, the factors to be considered to ensure better outcomes during ORIF (open reduction and internal fixation), and external fixation in the treatment of distal radial fractures are described. The review also details the common accompanying injuries and management methods.
Purpose This study compared the radiologic and clinical outcomes of metacarpal fractures treated with two minimally invasive surgical techniques: Kirschner wire (K-wire) fixation and headless screw fixation. Materials and Methods This study included 52 patients (46 males and 6 females; age 18-55 years) with distal metacarpal fractures (middle and distal shaft, including the neck) who had undergone K-wire fixation or headless screw fixation. All subjects were followed up for at least six months. The radiologic assessments were performed to evaluate the angular deformity and shortenings. The total active motion (TAM), grip strength, and patients’ subjective functional assessment were measured to evaluate the hand function. The time taken to return to work (RTW) and adverse events were analyzed. Results Of the 52 cases, metacarpal fractures treated with headless screw fixation and K-wire fixation showed a significant difference associated with early RTW (p<0.05). There were no significant differences between the subjects treated with K-wire fixation and those with headless screw fixation in terms of the radiologic measurement, hand function examinations, complications, and adverse events (p>0.05). Conclusion After a six-month follow-up, minimally invasive K-wire fixation and headless screw fixation produced similar clinical and radiologic outcomes in subjects with metacarpal fractures. Compared to K-wire fixation, however, headless screw fixation led to earlier functional recovery and might be a better option for treating metacarpal fractures in this regard.
Purpose To report the surgical results of the parapatellar approach for AO/OTA 33-C distal femoral intra-articular fractures. Materials and Methods Twenty-one patients with AO/OTA 33-C distal femoral intra-articular fracture were included. There were 11 cases of C2 and 10 cases of C3 fractures. The time of union and the coronal alignment were radiographically investigated. The complications related to surgery were clinically investigated, and a functional evaluation using the range of motion and Oxford knee score was performed to compare the surgical results according to fracture classification. Results In all cases, sufficient articular exposure and anatomical reduction were achieved with the parapatellar approach. No cases of coronal malalignment, loss of reduction, and plate failure were noted. On the other hand, in four cases (19.0%), an autogenous bone graft was performed due to delayed union on the meta-diaphyseal fracture site. There were no differences in the radiological and clinical outcomes of the C2 and C3 fractures. The knee joint pain and Oxford knee score were poorer in the delayed union group than the normal union group. Conclusion The parapatellar approach is useful for achieving an anatomical reduction of the articular surface of the distal femur and minimally invasive plating technique. Although satisfactory surgical results could be obtained regardless of the degree of articular comminution, a study of the risk factors of delayed metaphyseal fusion may be necessary.
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 This study evaluated the clinical and radiological outcomes of TFNA (Trochanteric Fixation NailAdvanced; Depuy Synthes) for the treatment of proximal femur fractures. Materials and Methods This was a retrospective study of 64 patients diagnosed with a proximal femur fracture from January 2019 to November 2019. The patient’s demographic data, preoperatively and postoperatively Koval grade, modified Harris hip score, EQ-5D (Euro-Qol-5 Dimension), sliding and advancement of the blade, radiologic outcome, and complications were investigated. Results Fifty patients were available for evaluation at one year postoperatively. The patients reported the following: the Koval grade decreased after surgery; the modified Harris hip score decreased from 78.56±8.88 to 72.74±6.59 (p=0.149); the mean EQ-5D decreased from 0.75±0.09 to 0.72±0.06 (p=0.000). Satisfactory reduction was achieved on a postoperative radiographic examination in 47 patients in six months. Complications occurred in seven cases. Conclusion TFNA is considered an appropriate implant for treating intertrochanteric fractures of the femur with a minimum follow-up of one year.

Purpose This study was undertaken to compare outcomes of screw fixation and non-fixation of a small-sized posterior malleolar fragment involving less than 25% articular surface in ankle trimalleolar fractures.
Materials and Methods: A total of 32 consecutive ankles (32 patients), with posterior malleolar fragment involving 15%-25% of the joint surface, were enrolled in the study. Patients were divided into 2 groups according to whether the fragment was fixed or not (fixed: 20 ankles, non-fixed: 12 ankles).
The minimum follow-up period was 12 months. Median size of the posterior malleolar fragment in the fixed and non-fixed groups were 24.6% (range, 22.3%-25.0%) and 22.1% (range, 17.4%-24.3%), respectively. Complications as well as clinical and radiographic outcomes were compared and analyzed between the two groups.
Results: Clinical outcomes, including American Orthopaedic Foot & Ankle Society (p=0.501), visual analogue scale (p=0.578), and ankle range of motion (p=0.552), showed no difference between groups at the final follow-up. No differences were obtained in the radiographic outcomes, including joint stepoff (p=0.289) and fragment gap (p=0.289). Complications, including 1 case of delayed union and 1 case of wound infection, were reported in the fixed group.
Conclusion: Clinical outcomes and radiographic outcomes of the non-fixation group were satisfactory and comparable to the fixation group. Our results indicate that anatomical reduction with small-sized posterior malleolar fragment in ankle trimalleolar fractures is sufficient for satisfactory outcomes, without the need for additional internal fixation.
Pediatric femoral neck fracture is an uncommon injury with a high complication rate, regardless of the appropriate diagnosis and management. The bony anatomy and blood supply of the proximal femur in a skeletally immature patient differ from those in adult patients. Generally, these fractures result from high-energy trauma, but pathologic hip fractures also occur, usually from low-energy trauma. Pediatric femoral neck fractures are categorized using the Delbet classification system. This classification guides management and aids clinicians in determining the risk of avascular osteonecrosis. The ideal surgical treatment is determined by the fracture type and the age of the patient. Reduction, which is achieved using a closed or open procedure, combined with stable fixation and/or cast immobilization, is recommended for most of these fractures. Anatomical reduction within 24 hours from the injury may result in a good surgical outcome. Although the effects of capsular decompression after reduction and fixation have not been established, decompression is easy to perform and may reduce the risk of avascular necrosis. Despite appropriate management, osteonecrosis can occur after all types of pediatric femur neck fractures. Other complications include coxa vara, nonunion, and premature physeal arrest.
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 evaluated the clinical results and implant safety of a newly developed implant, Trochanteric Fixation Nail-Advanced (TFNA; DePuy Synthes), in the treatment of proximal femur fractures. Materials and Methods This was a retrospective cohort study of 26 patients diagnosed with proximal femur fracture and treated surgically with TFNA. The patients’ demographic data, surgical data, radiologic findings, and functional outcomes, including complications, were evaluated. Results The mean age of the patients was 71.2 years (95% confidence interval [CI], 68.2-74.2); 65.4% were female. The mean Carlson comorbidity index score was 5.4, and the mean Koval grade before fracture was 2.1. Fracture classification included four cases of AO/OTA 31.A1, nine cases of A2, six cases of A3, and seven cases of 32A including six cases of atypical femoral fractures. The mean operating time was 53.3 minutes (95% CI, 43.6-63.1). There were no early postoperative complications, such as postoperative infection, deep vein thrombosis, pulmonary embolism, or in-hospital death, except one case of pneumonia. The mean Koval score at the postoperative six-month follow-up was 2.9. EuroQol-5 Dimension (EQ-5D) increased from 0.05 to 0.54 after three months and 0.72 at six months postoperatively. Bone union was observed in all cases with a mean union time of 12.9 weeks. No implant failure occurred, and no cases required secondary revision surgery. Conclusion A new intramedullary nail system, TFNA, showed excellent outcomes and safety in the surgical treatment of proximal femur fractures.

Purpose This study evaluated the usefulness of a silicone ring tourniquet by analyzing the changes in the perioperative hemoglobin (Hb) levels or amount of perioperative bleeding compared to those of a pneumatic tourniquet or no usage during minimally invasive plate fixation for distal femoral fractures. Materials and Methods From January 2017 to December 2019, 30 patients who underwent minimally invasive plate fixation using a locking compression plate for distal femoral fractures were evaluated and classified as a silicone ring tourniquet (Group 1), a pneumatic tourniquet (Group 2), and no usage (Group 3). The variables for analysis were age, sex, preoperative Hb (preHb), postoperative 72-hour Hb (postHb), differences between preHb and postHb (preHb-postHb), amount of intraoperative and overall transfusion, estimated unit of transfusion corrected by preHb-postHb and total transfusion (Hb-lost), amount of intraoperative and postoperative and total bleeding. One-way ANOVA was used to identify the differences between the groups. Results The age, sex, operation time, preHb, preHb-postHb, amount of intraoperative and overall transfusion and Hb-lost were similar in the two groups. The amount of intraoperative bleeding was significantly lower in Group 1 than Group 3 (p=0.004), but there was no difference in the amount of postoperative and total bleeding between the two groups. Conclusion The use of a silicone ring tourniquet in the minimally invasive plate fixation for distal femoral fractures decreased the amount of intraoperative bleeding compared to no use of a tourniquet.

Purpose This study analyzed the morphological features of the contralateral femur without an atypical fracture by constructing a three-dimensional model with an actual size medullary canal. Materials and Methods Lateral and anterior bowing of the shaft were measured for 21 models, and the shape of the medullary canal was analyzed. To eliminate the projection error, the anteroposterior (AP) femur was rotated internally to the extent that the centerline of the head and neck, which is the ideal position of cephalomedullary nail screw, was neutral, and the lateral femur matched the medial and lateral condyle exactly. Results The lateral bowing and anterior bowing was an average of 5.5° (range, 2.8°-10.7°; standard deviation [SD], 2.4°) and 13.1° (range, 6.2°-21.4°; SD, 3.2°), respectively. In the area where lateral bowing increased, the lateral cortex became thicker, and the medullary canal was straightened. On the lateral femur, the anterior angle was increased significantly, and the diameter of curvature averaged 1,370.2 mm (range, 896-1,996 mm; SD, 249.5 mm). Conclusion Even if the anterolateral bowing increases in the atypical femur, the medullary canal tends to be straightened in the AP direction. So, it might be considered as a reference to the modification of an intramedullary nail to increase the conformity.
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 compared the clinical and radiological results between two groups of patients with percutaneous fixation or conventional fixation after hardware removal. MATERIALS AND METHODS The study analyzed 68 patients (43 open fixation and 43 percutaneous screw fixation [PSF] 25) who had undergone fixation for unstable thoracolumbar fractures. The radiologic results were obtained using the lateral radiographs taken before and after the fixation and at the time of hardware removal. The clinical results included the time of operation, blood loss, time to ambulation, duration of the hospital stay and the visual analogue scale. RESULTS The percutaneous pedicle screw fixation (PPSF) group showed better results than did the conventional posterior fixation (CPF) group (p<0.05) in regard to the perioperative data such as operation time, blood loss, and duration of the hospital stay. There were no significant differences in wedge angle, local kyphotic angle, and the ΔKyphotic angle on the postoperative plane radiographs between the two groups (p>0.05). There were no significant differences in the wedge angle and local kyphotic angle after implant removal (p>0.05) between the two groups as well. However, there were significant differences in the segmental montion angle (p<0.001), and the PPSF group showed a larger segmental motion angle than did the CPF group (CPF 1.7°±1.2° vs PPSF 5.9°±3.2°, respectively). CONCLUSION For the treatment of unstable thoracolumbar fractures, the PPSF technique could achieve better clinical results and an improved segmental motion angle after implant removal within a year than that of the conventional fixation method.

The fixation methods that can be used for unstable posterior pelvic ring injuries have undergone many innovative changes due to the recent development of surgical and imaging techniques. After understanding the appropriate indications of first and second sacroiliac screw fixation and spinopelvic fixation, innovative methods, including the trans-sacral screw fixation, posterior tension-band plate fixation, and the S2AI screw, would be chosen and applied. Considering the anatomical complexity and proximity to the surrounding vessels and nerves in the posterior fixation, the safe zone according to the fixation options should be well understood in preoperative planning. Moreover, the functional reduction of the posterior pelvic ring through the reduction and fixation of the anterior lesion should be achieved before placing the implant to reduce the number of malposition-related complications.

PURPOSE Radial head fractures, which account for 33% of all fractures, are treated depending on the Mason classification. In comminuted type 3 fractures, open reduction internal fixation (ORIF), and radial head arthroplasty are the treatment options. This study examined the clinical outcome of modified Mason type 3 radial head fractures using ORIF with a plate. MATERIALS AND METHODS The medical records and image of 33 patients, who underwent ORIF for modified Mason type 3 radial head fractures, were reviewed retrospectively. The preoperative plain radiographs and computed tomography images were used to examine the location of the fracture of the radial head, the number of fragments, union, joint alignment, and traumatic arthritis at the final follow-up. The range of motion (ROM) of the elbow at the last follow-up, pain score (visual analogue scale), modified Mayo elbow score (MMES), and complications were analyzed for the clinical outcome. RESULTS Of the 33 cases, 14 were men and 19 were women. The mean age was 41.8 years and the average follow-up period was 19 months. The functional ROM was divided into three groups according to the number of bone fragments: 141.2°±9.3° of 3 (n=20), 123.8°±18.5° of 4 (n=7), 100.7°±24.4° of more than 4 (n=6). Furthermore, the MMES were 88.2±2.9, 83.7±4.3, and 77.3±8.4, respectively (p=0.027). Depending on the radial head fracture location, the ROM and MMES were 130.7°±7.5° and 82.1±4.7, respectively, with poor outcomes on the ulnar aspect compared to 143.1°±3.8° and 89.9±3.2 on the radial aspect. CONCLUSION Various factors, such as the degree of crushing and location involved in the clinical outcome. In particular, the result was poor in the case of more than four comminuted fragments or chief position located in the ulnar aspect. In this case, radial head arthroplasty may be considered in the early stages.

PURPOSE The prevalence of osteoporotic sacral fractures is increasing. Traditionally, conservative treatment is the 1st option, but it can increase the risk of comorbidity in the elderly. To reduce the complications and allow early mobility, iliosacral screw fixation with cement augmentation will be one of the treatment options for patients with osteoporotic sacral fractures. MATERIALS AND METHODS This study reviewed 25 patients (30 cases) who had undergone percutaneous iliosacral screw fixation with cement augmentation for osteoporotic sacral fractures from July 2012 to December 2018 with a minimum follow up of six months. The clinical outcomes were assessed using the measures of pain (visual analogue scale [VAS] score), hospital stay and the date when weight-bearing started. All patients were evaluated radiologically for pull-out of screw, bone-union, and cement-leakage. RESULTS Bone union was achieved in 30 cases (100%). The mean duration of the hospital stay was 24 days (4–66 days); weight-bearing was performed on an average nine days after surgery. The VAS scores immediately (3.16) and three months after surgery (2.63) were lower than that of the preoperative VAS score (8.3) (p<0.05). No cases of cement-leakage or neurologic symptoms were encountered. Two patients (6.7%) experienced a pulling-out of the screw, but bone-union was accomplished without any additional procedures. CONCLUSION Percutaneous iliosacral fixation with cement augmentation will be an appropriate and safe surgical option for osteoporotic sacral fractures in the elderly in terms of early weight-bearing, pain reduction, and bone-union.
PURPOSE The aim of this study is to investigate the clinical performance and safety of Zimmer® natural nail cephalomedullary nail (ZNN CM nail) in the treatment of proximal femur fractures. MATERIALS AND METHODS The following research was conducted as a prospective, non-comparative, single center outcome study. Upon providing written informed consent, enrolled patients' data were collected and analyzed. Postoperative follow-up visits were scheduled at 6 weeks, 3 months, 6 months, and 1 year. Follow-up evaluation included radiographic assessment, physical examination, and quality of life and adverse events reports. RESULTS Thirty-nine patients were available for evaluation at one year postoperative. The patients reported the mean EuroQol-5 Dimension score increased after surgery: from 0.4 points at discharge (n=49) to 0.6 points at 1-year post-surgery (n=39). The mean Harris hip score also increased after surgery: from 56.3 points at discharge (n=49) to 72.1 points at 1 year (n=12). Bone union was seen in 64% (n=16) in 6 months and 95% (n=37) in 1 year. CONCLUSION The results of this 1-year follow-up study affirmed the effectiveness and safety of the ZNN CM nail in the treatment of proximal femur fractures.

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.
