PURPOSE For fixation of the large posterior malleolar fracture fragment, indirect anterior fixation with cannulated screw has been widely used, but the anatomical reduction is not always obtained. The purpose of this article is to evaluate the clinical result of posterior malleolar fractures treated with anatomical reduction and internal fixation using posterior approach. MATERIALS AND METHODS We have analyzed the 15 patients with posterior malleolar fractures, treated with posterior approach from August 2005 to August 2008. The mean follow up period was 17.6 months, We have reviewed the perioperative joint integrity, method of operation, postoperative care, bony union and complication. A clinical outcome was evaluated by AOFAS (American orthopedic foot and ankle society) scaling system and Olerud & Molander scoring system. RESULTS Among 15 cases, posterolateral approach and posteromedial approach were chosen in 9 cases and 6 cases respectively. The radiologic unions were achieved at 12.4 (12~18) weeks. Mean AOFAS score was 90.3 (72~98), and Olerud & Molander score was "excellent" in 5 cases, "good" in 7 cases, "fair" in 1 case and "poor" in 2 cases. Postoperative complications in 2 cases revealed a posttraumatic arthritis and a scar band contracture respectively. CONCLUSION In posterior malleolar fracture of ankle joint, the integrity of joint has closely affected clinical outcomes. We suggest that a posterior approach for posterior malleolar fracture with especially incarcerated fragments and comminuted fractures, can be a useful method for anatomical reduction and stable fixation, and satisfactory clinical results.

PURPOSE The purpose of this study was to evaluate and compare the clinical & radiological outcome between LCP and conventional T-plate fixation in the treatment of distal radial fracture. MATERIALS AND METHODS From January 2000 to October 2006, 26 patients were treated by LCP fixation and 20 patients were treated by conventional T-plate fixation for distal radial fracture. We used the X-ray to calculate the radial inclination, radial length and volar tilting, then compared the loss of correction after the operation between both groups. We also evaluated the clinical functional outcome by Mayo wrist score. RESULTS The average follow-up since operation was ten months in both LCP and conventional T-plate fixation group. According to Frykmann classification, there were 1 case of type 1 (4%), 2 of type 2 (8%), 5 of type 3 (19%), 14 of type 4 (54%), 1 of type 5 (4%), 2 of type 7 (8%), 1 of type 8 (4%), and to AO classification, 4 of type A (15%), 22 of type C (85%) in LCP group. In conventional T-plate group, according to Frykmann classification, there were 12 cases of type 3 (60%), 4 of type 4 (20%), 3 of type 7 (15%), 1 of type 8 (5%), and to AO classification, 6 of type B (30%), 14 of type C (70%). In LCP group, the loss of correction between immediate post-operation and last follow-up was about 1.03 degrees in radial inclination, -1.09 mm in radial length, -2.08 degrees in volar tilting at each, and in conventional T-plate group, 2.4 degrees in radial inclination, -0.82 mm in radial length, -2.11 degrees in volar tilting at each. There was no statistical significance (p>0.05) in two groups. In the clinical functional outcome (according to Mayo wrist score), 92% of patient showed above good result in LCP group and 85% of patient showed above good result in conventional T-plate group. There was no infection, delayed union. CONCLUSION Treatment by Interposition of fragments and shortening in the intractable nonunion of humerus with a bony defect can achieve not only good functional result, shortened bone union time and improved in shoulder and elbow motion.
