Surgical Treatment of AO/OTA 33-C Intra-Articular Distal Femoral Fractures through Parapatellar Approach: Suk Kyu Choo, Sung Tan Cho, Hyoung Keun Oh; J Korean Fract Soc 2022;35(1):1-8. Published online January 31, 2022; DOI: https://doi.org/10.12671/jkfs.2022.35.1.1

Abstract PDF: 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.

Comparing Outcomes of Retrograde Intramedullary Nail and Locking Plate Fixation in Distal Femoral Fractures: Byung-Ho Yoon, Bo Kwon Hwang, Hyoung-Keun Oh, Suk Kyu Choo, Jong Min Sohn, Yerl-Bo Sung; J Korean Fract Soc 2021;34(4):131-136. Published online October 31, 2021; DOI: https://doi.org/10.12671/jkfs.2021.34.4.131

Abstract PDF: 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.

Brachial Plexus Neuropathy after Revision of Clavicular Fracture Nonunion: A Case Report: Youngwoo Kim, Suk Kyu Choo, Neunghan Jeon; J Korean Fract Soc 2020;33(1):22-26. Published online January 31, 2020; DOI: https://doi.org/10.12671/jkfs.2020.33.1.22

Abstract PDF: We performed a revisionary open reduction and internal fixation for treating nonunion of the mid-shaft of the left clavicle with an autogenous cancellous bone graft. On postoperative day 4, the patient presented with neurologic deficits in the left upper extremity. We removed the implant and made a superior angulation to decompress the brachial plexus. At 6 months postoperatively, callus bridging and consolidation were visible and all hand and elbow functions were fully recovered. Our case suggests that brachial plexus neuropathy may be caused by stretching and compression after reduction and straightening of the nonunion site around adhesions or scar tissue. Therefore, care should be taken whether there are the risk factors that can cause brachial plexus neuropathy when revision surgery is performed for treating nonunion of a clavicle shaft fracture.

Abstract PDF: PURPOSE
To investigate the surgical outcomes of orthogonal locking compression plate fixation for distal humeral intraarticular fractures.
MATERIALS AND METHODS
This study included 18 patients presenting a distal humeral intraarticular fracture who were treated with orthogonal locking compression plate fixation. According to the AO/OTA classification, there were eight C2 and ten C3 fractures. We evaluated radiologic outcomes, clinical results with range of motion, operation-related complications, and functional score by Mayo elbow performance score (MEPS).
RESULTS
The a verage u nion t ime was 3.5 months, and there was no c ase of r eduction l oss of a rticular f racture at t he last follow-up. Additional surgical procedures were needed in the three cases of C3 fractures. There was one case of heterotrophic ossification and one case of K-wire irritation. The average range of motion of elbow joint was 7Â° to 122Â°, and functional results were graded as 14 excellent, three good, and one fair by MEPS.
CONCLUSION
Anatomical reduction and internal fixation with orthogonal locking compression plate could provide satisfactory surgical outcomes for the treatment of distal humeral intraarticular fracture.

The Surgical Outcome of Unstable Distal Clavicle Fractures Treated with 2.4 mm Volar Distal Radius Locking Plate: Suk Kyu Choo, Ji Ho Nam, Youngwoo Kim, Hyoung Keun Oh; J Korean Fract Soc 2015;28(1):38-45. Published online January 31, 2015; DOI: https://doi.org/10.12671/jkfs.2015.28.1.38

Abstract PDF

PURPOSE
This study evaluated the surgical outcomes of unstable distal clavicular fractures treated with a 2.4 mm volar distal radius locking plate.
MATERIALS AND METHODS
From August 2009 to August 2012, 16 patients with distal clavicle fractures underwent surgical treatment. Mean age was 36 years (18-62 years) and mean follow-up period was 12.9 months (6-32 months). Two cases were Neer type I, six cases IIa, three cases IIb, three cases III, and two cases V. For the radiologic assessment, union time and metal failure were evaluated, and coracoidiologic assessment, union time and metal failure were evaluatethe acromioclavicular joint. The clinical results were evaluated by range of motion, postoperative complication, and University of California at Los Angeles (UCLA) score.
RESULTS
Mean time to fracture union was 7.4 weeks (6-14 weeks) in all cases. No statistical difference in coracoid-clavicle distance was observed between immediate post-operation group and contra-lateral group (p=0.6), but an increase of 2.1 mm was observed in the last follow up group compared with the contra-lateral group (p<0.01). The UCLA scoring system showed excellent results in 15 cases and good results in one case. Acromial-clavicle instability occurred in one case so that metal removal and distal clavicle resection were performed.
CONCLUSION
A 2.4 mm volar distal radius locking plate can provide rigid fixation through several screw fixation in the short distal fragment and lead to satisfactory clinical outcomes in unstable distal clavicular fractures.

Minimally Invasive Plate Osteosynthesis for Humeral Proximal or Distal Shaft Fractures Using a 3.5/5.0 Metaphyseal Locking Plate: Hyoung Keun Oh, Suk Kyu Choo, Jung Il Lee, Dong Hyun Seo; J Korean Fract Soc 2012;25(4):305-309. Published online October 31, 2012; DOI: https://doi.org/10.12671/jkfs.2012.25.4.305

Abstract PDF

PURPOSE
Our study aimed to investigate the clinical and radiological results of humerus proximal or distal shaft fractures treated with minimally invasive plate osteosynthesis (MIPO) using a 3.5/5.0 metaphyseal locking plate.
MATERIALS AND METHODS
We reviewed the clinical and radiographic records of 17 patients with humeral proximal or distal shaft fractures who had undergone 3.5/5.0 metaphyseal locking plate osteosynthesis with a minimally invasive technique. We evaluated the results with respect to the anatomical reduction and union of the humerus shaft fracture through radiologic studies. We also evaluated the clinical results using the motion of shoulder and elbow functional outcome, American Shoulder and Elbow Surgeons (ASES) score, Mayo elbow performance score (MEPS), and postoperative complications.
RESULTS
Complete union was achieved in all cases. The mean union time was 14.2 weeks. According to the functional outcome rated by the ASES score and MEPS, 15 cases were considered excellent and 2 cases were good. There were no cases of surgically-related complications like metal failure, loss of anatomical reduction, or postoperative nerve injuries.
CONCLUSION
Using a 5.0 metaphyseal locking plate for humerus shaft fracture has the limitation that difficulties can arise in achieving sufficient screw fixation for small bony fragments. The 3.5/5.0 metaphyseal locking plate used in MIPO for humerus 1/3 proximal or distal shaft fractures was concluded to give good clinical and radiologic results.

Anterior Knee Pain after Intramedullary Nailing for Tibial Shaft Fractures: Suk Kyu Choo, Hyoung Keun Oh, Hyun Woo Choi, Jae Gwang Song; J Korean Fract Soc 2011;24(1):28-32. Published online January 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.1.28

Abstract PDF

PURPOSE
To analyze the possible causes and incidence of the chronic anterior knee pain follow after closed intramedullary nailing for the tibial shaft fractures, in a retrospective aspect.
MATERIALS AND METHODS
52 patients who treated with intramedullary nailing for the tibial shaft fractures from January 2001 to October 2008 were reviewed. We analyzed the relationship between knee pain and the variables (sex, age, types of fracture, protrusion extent of intramedullary nailing on proximal tibia). The aspects of pain, its onset and relieving time, and how much it influences on daily living were analyzed retrospectively. For categorical variables, group variences were estimated using Chi-square test.
RESULTS
34 patients of 52 (65%) complaint of anterior knee pain followed after intramedullary nailing, and there were no statistical differences between pain and sex/age (p>0.05). Incidence of anterior knee pain becomes higher as the severity of fracture increases, but there was no statistical difference between pain and intramedullary nailing protrusion. Pain severity was mostly not influencing on daily living, and it mostly responded to conservative treatment.
CONCLUSION
The incidence of anterior knee pain followed after intramedullary nailing was 65%, and its severity was mostly not influencing on daily living. There were no significant differences between pain and sex, age, protrusion extent of intramedullary nailing on proximal tibia, but as the severity of frature increases, the incidence of anterior knee pain became higher.

Mid-term Results of Distal Tibial Fractures Treated with Ilizarov External Fixator: Suk Kyu Choo, Kyung Wook Nha, Hyoung Keun Oh, Dong Bong Lee; J Korean Fract Soc 2007;20(4):323-329. Published online October 31, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.4.323

Abstract PDF: PURPOSE
We analyed the mid-term results of distal tibial fractures treated with ilizarov external fixator and functional results according to delayed metaphyseal healing and fracture pattern.
MATERIALS AND METHODS
We reviewed 23 distal tibial fractures treated with ilizarov external fixator followed for minimum two year (mean 53 months). There were 10 A fractures, 2 B fractures, and 11 C fractures according to the AO classification. Radiographically, we analyzed bony union time according to translation of diaphyseal-metaphyseal fracture line and assessed arthritic score. Functional results was assessed with AOFAS score and analyzed according to delayed healing and fracture pattern.
RESULTS
Average union time was 21 weeks. Delayed healing of metaphyseal fracture line was associated translational displacement >3 mm (p=0.01). AOFAS scrore was averaged to 68 and there was no stastical significance between delayed metaphyseal healing and functional results (p=0.31). But, low AOFAS score and arthritis score was related to fracture type (p=0.02). In 11 C fractures, radiographic arthritic change were developed in 6 cases (55%).
CONCLUSION
The main prognosis of distal tibial fractures depends on articular involvement and to shorten the external fixation time, metaphyseal fracture should be reduced within 3mm.

Abstract PDF: PURPOSE
To determine the usefulness of flexible intramedullary fixation in pediatric forearm diaphyseal fractures.
MATERIALS AND METHODS
We reviewed 22 cases of forearm diaphyseal fractures treated with flexible intramedullary nail and K-wire. The radiographic assessment was based on the time to union, maintenance of reduction and angular deformity. The functional outcome was assessed with the range of motion and complications at last follow up.
RESULTS
Average length of follow up was 13.9 months with mean age of 10.8 years and the time to union was 5.2 weeks. There were no angular deformity and fuctional results were excellent in all cases. There were 5 cases of soft tissue irritation of nail insertion site as post operative complication which was resolved after nail removal.
CONCLUSION
Flexible intramedullary for pediatric forearm bone fractures is an effective and safe method which gives a good functional outcome.

Flexible Intramedullary Nail Fixation of Pediatric Femoral Shaft Fracture: Suk Kyu Choo, Byung Jik Kim, Hyun Wook Chung; J Korean Fract Soc 2005;18(1):60-64. Published online January 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.1.60

Abstract PDF: PURPOSE
To traditional treatment of pediatric femoral shaft fracture has been a traction and spica cast application. But flexible intramedullary nail fixation has been introduced as an alternative to other treatment modalities. With this in mind, we analyzed the clinical and radiologic results of flexible intramedullary nail fixation of pediatric femoral shaft fractures.
MATERIALS AND METHODS
We analyzed 12 patients (13 cases) who were treated with flexible intramedullary nail and followed up for at least 6 months at the department of Orthopedic Surgery, Inje University Ilsan Paik Hospital since May, 2002.
RESULTS
In all 12 patients (13 cases) involving 1 case with reoperation because of reduction failure, average duration of bone union was 12.6 weeks. There were no considerable complications except mild post-op knee pain and limitation of motion.
CONCLUSION
In spite of relatively short term study, a flexible intramedullary nail fixation seems to be a useful method without serious complications on pediatric femoral shaft fracture. However, in big or older pediatric patients, interlocking intramedullary nail fixation may be a better choice rather than a flexible nail fixation because of it's insufficient stability.

Neurologic Complications of Elbow Fractures in Children: Suk Kyu Choo, Gyu Won Park; J Korean Soc Fract 2002;15(4):595-600. Published online October 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.4.595

Abstract PDF: PURPOSE
We analyzed neurologic complications of the elbow fractures in children and evaluated clinical results of type of fractures, frequency of nerve injuries and displacement of fracture fragments and spontaneous recovery of each nerve injuries.
MATERIALS AND METHODS
We analyzed 17 child-patients (20cases) with nerve injuries who were treated conservatively and follewed up for at least 1 year since December 1999. and we analyzed type of fractures, differences between fracture type and nerve injuries, frequency of each nerve injuries and periods of spontaneous recovery of each nerves.
RESULTS
There were all 148 elbow fractures in children. Children with neurologic complications were 17(20 nerves) and 14 in supracondylar and 3 in medial epicondylar fractures. There were 6 in radial nerve, 8 in ulnar nerve, 3 in median nerve and 3 in anterior interosseous nerve. Both ulnar and median nerve injuries were 3 patients. They were recovered spontaneously and mean periods of recovery was 7.3 weeks, 6.5 weeks in radial nerves, 7.0 in median nerves, 7.6 in anterior interosseous nerves, 7.8 in ulnar nerves and radial nerve recovery was most fast than any others. One patient with ulnar nerve injury who was diagnosed medial epicondylar fracture recovered 2 weeks after excision of nonuioned fragment. Among 14 supracondylar fractures, there was 11 posteromedial displacement, 1 posterolateral and 2 posterior. Most of them was displaced posteromedially.
CONCLUSION
All nerve injuries happened in supracondylar and medial condylar fractures and almost recovered. Nerve injuries in the supracondylar fractures was displaced fractures than nondisplaced simple fractures and displacement of fracture fragment and nerve injuries was not agreed with previous published books or papers. We recommand that observation is the appropriate way to manage these nerve injuries in most cases than immediate operation for excision.

External Fixation of Displaced Proximal Humeral Fracture: Suk Kyu Choo, Byung Jik Kim, Jin Hwan Kim, Seung Yeub Suk, In Hwan Hwang; J Korean Soc Fract 2002;15(3):379-384. Published online July 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.3.379

Abstract PDF: PURPOSE
Proximal humerus fractures are relatively frequent and have variable treatment mothods. It is important to resolve union of the fracture site, good range of motion and function through the early ambulation in treatment results. We will know whether it is recommendable treatment or not and analyze the results of treatment on the effectiveness of the external fixator in two or three part fractures of the proximal humerus fractures.
MATERIALS AND METHODS
From May, 1999 to April, 2001, 8 cases in 8 patients were treated by external fixator on the proximal humerus fractures. Mean age was 44.7yrs(11 to 68 yrs), two part fracture 6 cases, three part fracture 2 cases in fracture classification by Neer. We treated 3 cases with ring external fixator, 4 cases with monoplane external fixator. We referred chart and radiographics to patients and assessed the results by Neer 's shoulder function table through final follow-up or phone call.
RESULTS
In all cases, we obtained bone union without neuroparalysis, neurovascular injury, avascular necrosis and other complications. Mean bone-union time was 7 weeks(5 to 12 weeks). Final functional assessments are excellent or good in 7 cases, poor in 1 case.
CONCLUSION
We obtained comfortable results after we performed external fixation on proximal humerus fracture and bone union was acquired and removed external fixator at 7 weeks through early ambulation. We think procedure has brief, low soft tissue damage, high stability and motily. Thus we think it is recommendable treatment on the displaced proximal humerus fractures.

Treatment of rotational malalignment after interlocking intramedullary nailing of femur : Report of a case: Suk Kyu Choo, Byung Jik Kim, Byung Hee Min; J Korean Soc Fract 1999;12(4):833-836. Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.833

Abstract PDF: Rotational malalignment after IM nail of femur is a common problem and if the deformity is great, may cause pain, limitation of motion, even require corrective osteotolny later. The rotational malalignment of femur is not easy to find out during operation because prominant landmarks is lack. We experienced 25 years old male patient with 45 of internal malalignment of femur after IM nail at other hospital. The patient was treated by corrective osteotomy at the fracture site and exchange nailing, but we confronted the obstacle that was remained rotatonal unstability after slotted nailing, and we have to use additional plate fixation. This problem can be prevented by using rigid unslotted nail.

Use of Interlocking Intramedullary Nail in Treatment of Delayed Union or Nonunion of the Long Bone Fractures: Suk Kyu Choo, Byung Jik Kim, Han Suk Ko, Jeong Gook Seo, Jin Gu Kim, Jun Woo Chang; J Korean Soc Fract 1998;11(4):761-768. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.761

Abstract PDF

Of the several nonoperative and operative options described for the treatment of delayed union and nonunion of the long bone, interlocking nailing with reaming offect of internal splint, autogenous bone graft and early return to a normal way of life. The purpose of this study is to evaluate the usefulness and complication of intramedullary(IM) naling with reaming by retrospective method. We treated 34 patients with delayed union or nonunion of the tibia, femur, and humerus by interlocking nailing with reaming between January 1992 and December 1996. The results were as follows ; 1. Of the 34 cases, there were 13 tibia fracture, 17 femur fracture, 4 humerus fracture. Half of them were ununited and another half were delayed in fracture healing. 2. Previous methods of treatment were conservative treatment in 2 cases, external fixator in 2, plate & screws fixation in 8, Ender nail in 2, Kuntscher nail in 2 and interlocking nail in 7 among 24 cases of cloed fracture and external fixator in 8 and interlocking nail in 2 among 10 cases of open fracture. 3. Twenty-five patients were treated with closed nailing and 9 were treated with open nailing. Iliac bone graft was performed at 3 cases and fibulotomy was performed at 1 case. 4. Union was obtained in 33 cases and 1 case needed additional bone grafting to achieve union. 5. Postoperative complications were one nonunion, two evtry site pain, one screw breakage, one heterotopic ossification, and one postoperative infection. Interlocking nailing with reaming was associated with a high union rate(97%) in our eries. The authors believe that IM nailing with reaming is a useful option for treatment of delayed or nonunion of the long bone fracture.

Surgical Treatment of Comminuted Distal Radius Fracture using External Fixators: Suk Kyu Choo, Byung Jik Kim, Han Suk Ko, Young Lim, Jeong Gook Seo, Jae Kie Shin; J Korean Soc Fract 1996;9(2):303-310. Published online April 30, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.2.303

Abstract PDF: Comminuted fractures of distal radius are usually unstable and complex injuries, which require prolonged treatment and often result in some degree of permanent disability. Previous treatment was mainly closed reuction and cast immobilization, and operative treatment of accurate open reduction, internal fixation and bone graft when needed. But recently ligamentotaxis of the fracture using external fixation device has been widely employed. Which could be followed up for 12 cases of comminuted fractured of distal radius operated with external fixators, more than 1 year, during the period of September 1990 to September 1994 at Seoul Paik Hospital was reviewed. According to Frykmalls classification, the most common type was type VIII (7 cases, 58.3%). There was 1 open fracture, and 7 combined injuries of ipsilateral upper extremity. According to AO classification, 9 cases(75%) were type C2 and C3. The most common cause was failing down from a height(6 cases). Additional limited internal fixation was done in 5 cases, all 12 cases were treated external fixators. Results were defined with modified Gartland & Werleys demerit pointing system, exellent was 6 cases(50fr), good wa,i 4 cases(33.3F)), poor was 2 cases. Surgical treatment using external fixators and/or limited open reduction was good Inethod for comminuted distal radius.

Treatment of humeral shaft fracture by interlocking IM nail: Byung Jik Kim, Jung Gook Seo, Suk Kyu Choo, Yoon Seong Yoon; J Korean Soc Fract 1994;7(2):642-647. Published online November 30, 1994; DOI: https://doi.org/10.12671/jksf.1994.7.2.642

Abstract PDF: The ideal treatment for humeral shaft fractures has been a topic of discussion for long times. Conventionally conservative methods like hanging arm cast, coaptation splint and functional brace were used. The operative treatment included plate and screws, intramedullary rods were used. The many known advantage of interlocking nails used in femur and tibia fractures were recently applied to humeral shaft fracture. Among them Seidel nail developed by Dr. Seidel in 1989 was inserted by splitting the rotator cuff and distal locking by expanding the distal tip of the nail through a long screw driver. This study is a preliminary report of first 10 cases of humeral shaft fracture which was internally fixed with Seidel nail during the period of September 1992 to September 1993. The findings are as follows. 1. 9 out of 10 cases(90%) achieved union. 2. Average union time was 10 weeks. 3, According to Neers shoulder functional score, 8 patients(80%) achieved either satisfactory or excellent shoulder function postoperatively. 4. 2 complications occurred. One nonunion and one distal fixation failure. Since fixation of humeral shaft fracture, by Seidel nail can achieve high union rate and good shoulder function, it should be considered as one of many methods to treat humeral shaft fracture.

Abstract PDF: Management of subtrochanteric fractures of the femur is difficult because it occurs in bone that is predominantly cortical and high stress concentrates in this region. The subtrochanteric fracture is difficult for the accurate reduction and maintenance because many of these fractures are cmminuted from high velocity trauma and its proximal fragment is severely displaced by adjacent strong muscles pooling. Therefore, as a rule we prefer to treat subtrochanteric fractures by operative means if possible. Many internal fixation devices have been recomended for use in subtrochanteric fractures and their selection should be based on the individual fracture anatomy. In recent years, generally accepted two methods are intramedullary nailing and plate fixation. We have reviewed our experience using the intramedullary fixation on 14 cases of subtrochanteric femur fracture and compared the result with those of 14 cases of plate fixation. All the 28 cases were treated at the Department of Orthopedic Surgery, Seoul Paik Hospital, Inje University in the period from March 1988 to March 1993. Intramedullary fixation were implanted with shorter operating time, smaller incisions, and less intraoperative bleeding. The intramedullary fixation group had a shorter covalescence and earlier full weight-bearing but no significant difference in fracture union rate with plate fixation group. We conclude that with careful surgical technique, the intramedullary fixation was a more suitable method for the treatment of the subtrochanteric femoral fractures.
