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.
