Outcome of Fracture Distal End of Radius Treated By A Non-Bridging External Fixator

Abstract

Background: Fractures of the distal radius are among commonly encountered problems, which need optimal reduction and early rehabilitation, to provide early functional independence. Non-bridging external fixation which is relatively easy to apply, versatile, maintains reduction and allows early joint mobilization. Thus we analyzed the utility of non-bridging external fixator in fractures of distal end radius in terms of functional and radiological outcome in the rural Indian population. Material & methods: This prospective study is done in 22 patients (24 cases) of fresh fractures of distal end radius either extra or intra-articular. All patients were treated with non-bridging external fixator and were assessed for outcome functionally by DASH score, for union and radiological parameters. Results: Average age of patients was 47.27 years. Mean flexion-extension arc was 147° (73° flexion and 74° extension), mean pronation-supination arc was 164° (79° supination and 85° pronation) and adduction and Abduction was 32° and 11° respectively at 16 weeks post-operatively. The average radial angle restored post operatively to 18.93° (range 12.7° to 25°). The average radial length restored to 11.68 mm (range 8 mm to 14.4 mm). The average volar angle restored post treatment was 7.61° (range 3.4° to 15°). The average DASH score at 16 weeks was 9.92 (range 0.9 to 14.2). Conclusion: Non-bridging external fixator in treatment of the distal radius fractures is an effective method of treatment, which can give excellent results in terms of functional and radiological outcome.
