O2595 FRACTURES OF THE DISTAL TIBIA: MINIMALLY INVASIVE PLATE FIXATION

Abstract

Introduction: Unstable fractures of the distal tibia that are not suitable for intramedullary nailing are commonly treated by open reduction and internal þxation and/or external þxation techniques. Treatment of these injuries using minimally invasive plate osteosynthesis (MIPO) techniques may offer the advantage of achieving adequate þxation whilst minimising soft tissue injury and damage to the vascular integrity of the fracture fragments. Purpose: We report our experience using MIPO techniques for the treatment of unstable fractures of the distal tibia. Method: A review of all patients who sustained an unstable fracture of the distal tibia treated by MIPO between 1998 and 2001 was undertaken. Twenty patients were identiþed. The mean age was 38.3 years (17 Ð 71). All fractures were closed, and were classiþed according to the AO system. Intra-articular fracture extensions were classiþed according to RŸedi and Allgšwer. Results: Sixty percent of patients achieved callus by 8 weeks. All patients achieved callus by 3 months. The mean time to full weight bearing was 12 weeks (8 Ð 17). By 6 months 18/20 patients had achieved union. The two remaining patients achieved union by 7 months without further surgery. There were no deep infections and only one malunion. There were no cases of failure of þxation. Conclusion: MIPO appears to offer a reliable method of þxation of fractures of the distal tibia that are unsuitable for intramedullary nailing. Our results suggest that this technique is associated with a lower risk of signiþcant complications than encountered with more traditional methods of þxation of such fractures.
