PURPOSE To evaluate risk factors of posterolateral articular depression and characteristics of the posterolateral fragment in lateral condylar and bicondylar tibial plateau fractures with joint depression. MATERIALS AND METHODS We reviewed 48 patients of Schatzker type II and type V (type II 34, type V 14) and evaluated risk factors of posterolateral articular depression according to the posterolateral fragment, fibular fracture, and Schatzker classification. We evaluated the position of articular depression and anterolateral fracture line of the posterolateral fragment and measured anterior to posterior lengths of the posterolateral fragment. RESULTS Posterolateral articular depression was found in 20 of 34 cases (59%) with coexisting posterolateral fragment and in 16 of 21 cases (76%) with coexisting fibular fracture. There was a significant difference in the occurrence of posterolateral articular depression with the existence of the posterolateral fragment and fibular fracture (p<0.001). Multivariate regression analysis revealed that fibular fracture increased the occurrence of posterolateral articular depression (odds ratio 24.5, 95% confidence interval 2.2-267.2). Fifty-seven percentage of the anterolateral fracture line of the posterolateral fragment existed posterior to the anterior margin of the fibular head. CONCLUSION This study showed that fibular fracture affects posterolateral articular depression in Schatzker type II and V tibial plateau fractures. Selecting a fixation device and performing fracture reduction requires a careful consideration since the anterolateral fracture line of the posterolateral fragment exists posterior to the anterior margin of the fibular head.

PURPOSE To determine the influence of osteoporosis on the results of percutaneous K-wire fixation for distal radius fractures. MATERIALS AND METHODS Between March 2007 and February 2011, Fifty seven patients who underwent fixative surgery with K-wires after closed reduction and those available for follow-up for at least 6 months were reviewed. They were divided into the two groups of T score -3 or more (group 1) and T score less than -3 (group 2). These groups were compared by the range of motion of the wrist and Disabilities of the Arm, Shoulder and Hand (DASH) score. Radiologic evaluations consisting of radial length, radial inclination and volar tilt were compared. In group 1 with 34 cases, the average age was 65.4 years (50 to 78 years) and T score was -1.97 (-0.1 to -2.93). In group 2 with 23 cases, the average age was 74 years (54 to 89 years) and T score was -4.11 (-3.1 to -6.97). RESULTS There was no statistical difference between group 1 and group 2 in terms of range of motion, DASH score and radiologic evaluations. CONCLUSION In the case of no volar side cortical comminution, percutaneous K-wire fixation can be applied for the treatment of distal radius fracture with osteoporosis.
PURPOSE Fractures of the distal humerus are one of the challenging injuries due to its complex anatomy and accompanied comminution. For dual plate fixation, orthogonal or parallel plating is widely used, but the better of the two is debatable. The purpose of this study was to report another fixation technique that yielded good clinical results with early bone union of distal humerus fracture, namely, posterior-posterior plate fixation. MATERIALS AND METHODS From March 2003 to March 2012, 20 patients with distal humerus fractures were treated by posterior-posterior plate fixation. The triceps reflecting approach was used with anterior transposition of the ulnar nerve. The mean age at the time of injury was 45 years (range, 26 to 78 years). By AO classification of distal humerus fractures, there were one case of A2 and B3 respectively, two cases of each A3, C1 and C3, and twelve cases of C2. RESULTS The mean period of complete bone union was 7.1 weeks (range, 4 to 11 weeks). The mean flexion-extension range of motion of the elbow joint at last follow-up was 116.2 degrees. The mean pronation was 81.2 degrees and supination was 83.1 degrees. Plates and screws were removed at about nine months after the initial surgery. No cases showed complications or required additional operation. CONCLUSION Posterior-posterior dual plates fixation resulted in stable bicortical screw fixation, and insertion of lag screws were possible without interference. Posterior-posterior plating could be an easy and stable fixation method that provides good clinical results.

PURPOSE We evaluated outcomes of treatment in medial condyle fracture of the distal humerus in children. MATERIALS AND METHODS Seven patients (4 females, 3 males) who were treated at the Pusan National University Hospital and followed-up until skeletal maturity after treatment were included. The average age at the time of fracture was 4.6 years (range, 2 to 10 years). Treatment was performed from 1 day to 6 months after the fracture: 4 patients underwent a surgical treatment for 17 days, 2 months, 2 months and 6 months after fracture, respectively. All fractures were Milch type 1. Five patients had Kilfoyle type 3, and two patients had type 2 fractures. Final outcomes were evaluated by the Mayo elbow performance score and carrying angle. RESULTS There were 3 excellent, 3 good and 1 fair result at the final follow-up. There was no elbow pain in any of the patients. One of the four patients who underwent a late surgical treatment received corrective osteotomy due to cubitus varus. All four patients had a limitation of elbow motion. The other three patients who had accurate diagnosis and treatment had a full range of motion. CONCLUSION Diagnosis of medial condyle fracture of the distal humerus based on plain radiograph is difficult in children due to its cartilaginous structures. When a patient shows pain, tenderness and swelling on the medial side of the elbow, an additional examination with magnetic resonance imaging may be required even if no fracture line is found in the radiograph. Accurate diagnosis and early treatment is important for good results.
PURPOSE To evaluate the efficacy of the augmentative locking compression plate fixation in the treatment of femoral shaft nonunion occurring after intramedullary nailing. MATERIALS AND METHODS Between July 2004 and September 2012, a total of 17 patients (twelve men, five women, average age 52.5 years) who had femoral nonunions after primary intramedullary nailing for femoral shaft fractures were reviewed. The mean period of nonunion after primary nailing was 18.5 months. Leaving the nail in situ, an augmentative locking plate was applied to the nonunion site with simultaneous autogenous bone grafting, except for five hypertrophic nonunions. We followed up all patients with plain radiograph and evaluated clinical status to determine bone union. RESULTS All patients demonstrated evidence of fracture union with an average follow-up time of 5.0 (range 2 to 9) months. The time of operation was an average of 115 (range 45 to 160) minutes, and mean blood loss was 345.9 (range 150 to 700) ml. Two patients noted discomfort at the distal portion of plate, and one noted discomfort of donor site, but functional limitation was not observed in all patients. CONCLUSION Augmentative locking plate fixation for diaphyseal femoral nonunion after intramedullary nailing is a reasonable treatment option with increased stability.
PURPOSE To evaluate the radiological results and complications of interlocking intramedullary nailing for segmental tibia fractures. MATERIALS AND METHODS Twenty-six patients (26 cases) who underwent interlocking intramedullary nailing for segmental tibia fractures between January 2003 and May 2011 were followed for more than one year. We evaluated the complications and statistically analyzed the factors influencing bone union, including open fracture, fracture site, reaming, postoperative angulation, and postoperative fracture gap. RESULTS Nineteen cases (73%) achieved bone union with one operation at an average of 7 months (range, 5 to 11). Seven cases had secondary procedures before achieving union. Complications included 7 cases of nonunion, 3 cases of incomplete peroneal nerve injury, 2 cases of superficial infection, 1 case of compartment syndrome. Factors showing statistically significant differences were open fracture, postoperative angulation, and postoperative fracture gap. Factors showing no statistically significant difference were fracture site and reaming. CONCLUSION Nonunion is the most common complication in interlocking intramedullary nailing for segmental tibia fractures. To minimize this complication, comprehension of surgical techniques to reduce anatomically and careful evaluation of the fracture are required.

PURPOSE The purpose of this study was to analyze the results of treating subtrochanteric femoral fractures with proximal femoral nail antirotation (PFNA). MATERIALS AND METHODS Twenty five consecutive patients diagnosed with subtrochanteric femoral fractures underwent intramedullary fixation using PFNA and followed-up for over 12 months. According to the Seinsheimer's classification, there were 2 type IIA, 9 type IIB, 2 type IIIA, 3 type IV and 9 type V. According to the AO classification, there were 10 type A, 9 type B and 6 type C. There were 16 cases of closed reduction group and 9 cases of limited open reduction group. Retrospectively, radiological outcomes were assessed at the union period, change of neck shaft angle, tip-apex distance, Cleveland index, sliding of lag screw and complication. RESULTS Union was achieved in 23 of 25 cases, over an average of 17 weeks. Limb length shortening below 2 cm occurred in 7 patients. The Cleveland index was shown in 80% of 5, 6, 8 and 9 zone; the tip apex distance was 19.6 mm; the mean sliding distance was 4.4 mm; and the mean change of femur neck and shaft angle was varus 3 degree at the final follow-up. Complications included 3 cases of delayed union and 2 cases of nonunion. CONCLUSION With its early bony union, ambulation, rehabilitation and low complication, PFNA is a useful and reliable choice for the treatment of subtrochanteric fractures of the femur. Limited open reduction and additional fixation such as cable grip are recommended if it is difficult to obtain anatomical reduction by closed reduction.

PURPOSE With the increase in the old age population, proximal humerus fractures have been increasing recently. However, complications after operative treatment, such as fixation failure, are common because of osteoporosis. We treated proximal humerus fractures in patients with osteoporosis conservatively, and evaluated the radiographic and functional results by analyzing the factors affecting the results. MATERIALS AND METHODS Nineteen out of 30 cases for whom the clinical follow-up was over 1 year were included in this retrospective study. There were 17 females and 2 males, and the mean age was 73.2 years. The causes were slip from a short height (18 cases) and a minor car accident (1 case). We evaluated the union period, nonunion, malunion and the Constant score and analyzed several factors affecting the functional result, such as age, fracture pattern, and malunion. RESULTS Seventeen cases (89.5%) obtained union within 12.8 weeks on average. Neck-shaft angle was 125.3degrees on average, with seven cases of malunion. The Constant score was 84.1 on average, and there were excellent scores in 11 cases, good scores in 4 cases, and fair scores in 2 cases. Fracture pattern, neck-shaft angle, or malunion did not affect the functional outcome, and elderly patients showed poorer shoulder function. CONCLUSION Proximal humeral fractures with osteoporosis may achieve a high rate of bony union when treated with conservative methods. Despite the common occurrence of malunion, a satisfactory functional outcome may be expected.
PURPOSE The purpose of this study was to report the outcome of treatment of humeral shaft fracture with retrograde intramedullary nail of advanced insertion opening. MATERIALS AND METHODS From April 2005 and August 2012, 22 patients with a humeral shaft fracture were treated by a single surgeon using the technique of retrograde intramedullary nail at Department of Orthopedic Surgery, Yeouido St. Mary's Hospital (Seoul, Korea). To avoid causing fractures at the insertion site, the entry point was more distally located than conventionally, and was extended proximally to include the proximal marginal cortex of the olecranon fossa. The outcome was evaluated clinically and radiologically. RESULTS The mean period of achievement of bony was 5.8 months (4-11 months). Additional fixations were needed in one patient with intraoperative lateral condylar fracture and 2 patients with postoperative nonunion. There were no limitations of movement or pain in the shoulder joint, and 8 cases had a 6.5degrees flexion contracture on average. CONCLUSION This retrograde intramedullary fixation technique using a distal entry portal near the olecranon fossa is particularly useful in humeral shaft fractures without a neurovascular injury. The risk of an intraoperative fracture (supracondylar fracture or fracture around the entry portal) can be decreased using this treatment. We recommend this technique because of the safety and the satisfactory outcome.

PURPOSE To compare the results between Proximal femoral nail antirotation II (PFNA II) and Zimmer natural nail Asia type (ZNN) for the treatment of stable intertrochanteric fractures. MATERIALS AND METHODS Between September 2011 and September 2012, 40 consecutive patients with stable intertrochanteric femoral fractures were treated with PFNA II or ZNN. We reviewed 20 cases of PFNA II and 20 cases of ZNN prospectively. We evaluated the operation time, amount of bleeding, mean hospital day, and capability of mobility and function using 'mobility score of Parker and Palmer' and 'social score of Jensen'. We also evaluated the reduction state by the Fogagnolo, Cleveland index, change of tip and apex distance (TAD), sliding distance of cervical screw, change of neck shaft angle and bone union time. RESULTS There were no significant differences between the groups treated with PFNA and ZNN. Both groups showed good clinical results. PFNA showed less TAD change and ZNN showed a shorter sliding distance of cervical screw, but they were not statistically different. The bone union time was approximately 13 weeks in both groups. CONCLUSION PFNA and ZNN produced good clinical and radiologic results in the treatment of stable intertrochanteric fractures. There were no significant differences between the groups. Both implants provide good stability and union, so we can conclude that they are both suitable for the treatment of stable intertrochanteric fractures.

PURPOSE To evaluate the efficacy of surgical treatment through retrospective comparison of minimally invasive percutaneous plate osteosynthesis (MIPPO) vs open plate fixation in the treatment of the distal femur fractures. MATERIALS AND METHODS Thirty-one patients with distal femur fractures from January 2002 to December 2010 were divided into two groups depending on the surgical method. Minimum follow up was 12 months. Group A consisted of 17 patients treated with MIPPO, and group B was comprised of 14 patients treated with open plate fixation. Clinical outcomes including operation time, transfusion rate, rehabilitation, range of motion, and interval change of postoperative C-reactive protein (CRP) were evaluated to assess postoperative inflammatory reaction, postoperative complications and clinical results with the use of Sanders criteria. RESULTS The operative time was 86/135 min and transfusion volume was 0.8/1.9 unit respectively. The postoperative 3-day and 7-day CRP were 7.4/1.5 mg% in group A and 10.3/2.4 mg% in group B, showing more minimal tissue injury and early recovery in group A. There were no significant differences in clinical results by Sanders criteria in both groups. CONCLUSION Both MIPPO and open plate fixation for the treatment of distal femur fractures showed comparably good results. However, the MIPPO technique is superior to group B in view of minimal tissue injury and operation time and was proven to lessen the transfusion rate.

In order to investigate the feasibility of a modified tension band combined with anti-gliding loop augmentation technique for the treatment of comminuted patellar fracture, 21 patients with comminuted patellar fracture were enrolled in this study. After the modified tension band wiring of patellar fracture, a cerclage wire was passed around the patella. Anti-gliding loops were made on the bending sites of Kirshner-wires. A knot was tied using both ends of the anti-gliding loops, and the cerclage wire was tightened using proximal knots. Bone union was achieved at 4.5+/-1.5 months postoperatively without nonunion. The Lysholm score was 87.1+/-2.8, and the range of motion of the knee was 2.1degrees+/-3.4degrees to 132.2degrees+/-6.5degrees at the last follow-up. The modified tension band combined with anti-gliding loop augmentation technique might be considered an alternative modification of modified tension band wiring for the treatment of comminuted patellar fracture.
Minimally invasive plate osteosynthesis (MIPO) is beneficial for proximal tibial fractures since these injuries are mostly caused by high energy traumas. The advantages of MIPO are minimization of soft tissue dissection and preservation of periosteal vascularization. Lateral plating has mostly developed as MIPO for proximal tibial fractures. We introduce minimal invasive percutaneous plate stabilization using a medial locking plate as alternative treatment for proximal tibial fractures.

The reamer crack, followed by breakage at its distal part occurred during intramedullary nailing of tibial shaft fracture. The broken reamer was trapped in the intramedullary canal, making it very difficult to pull out. We successfully extracted the broken reamer by retrograde impaction through the fracture site and completed intramedullary nailing procedure. Thus, we present this case with a review of the literature.
