O2594 THE USE OF HYBRID FIXATORS IN DISTAL TIBIA FRACTURES

Abstract

Aims: There has been recent interest in the use of external þxation for the treatment of distal peri-articular fractures. The current study was undertaken to evaluate the role of the hybrid external þxation system in the treatment of the distal tibial fractures. Methods: We treated 137 fractures of the distal tibia, of which 46 were treated with hybrid external þxation. The indication for this method of treatment was in the presence of an unstable extra-articular fracture and/or a severe comminution of the distal tibia, as well as an associated severe soft-tissue injury. Routine demographic data, clinical and radiographic þndings as well as reduction, outcomes and complications were recorded. Patients were evaluated with outcome scale of Ovadia and Beals. Results: There were 17 closed fractures and 29 open. Twenty-one extra -and 25 intrarticular fractures were managed with a Hybrid Fixator. All fractures achieved complete healing. Reductions of C-type fractures were within 0-2 mm in 16 and 3–5mm in 56 and > 5mm in 3 patients. The Hybrid External þxator was removed at an average of 17.5 weeks. Full weight bearing was achieved at a mean of 7.8 weeks. There were no intraoperative injuries to nerves or major vessels. Using the outcome scale of Ovadia and Beals, good-excellent results were achieved in 67% (n=31) subjectively and 72% (n=33) objectively. Two poor results occurred in patients with a varus malunion. Conclusion: External þxation is a satisfactory method of treatment for fractures of the distal tibia and is associated with fewer complications than internal þxation, because it limits the amount of soft tissue.
