A Prospective Observational Clinical and Radiological Study of a Modular Bridging External Fixator for Unstable Distal Radius Fractures

INTRODUCTION: Distal Radius Fractures (DRFs), with a reported annual incidence of 600,000, are common injuries treated by trauma surgeons. This prospective observational study aims to assess the efficacy of a modular external fixation system in the treatment of unstable distal radius fractures at 12-months follow-up. MATERIALS AND METHODS: Between December 2014 and December 2016, 35 patients (female: 21, male:14; mean age: 62.5), with unstable DRFs, treated with modular external fixation system, were selected for this prospective observational study. All the patients underwent clinical and radiological reviews at follow-up. RESULTS: At 12-month follow-up, a mean DASH score of 15.73 and a mean PRWE score 20.10 were recorded. Mean radial inclination was 19.92°; mean ulnar variance was 1.12 mm and mean palmar inclination was 9.76°. CONCLUSION: Modular external fixator system revealed clinically and radiologically effective in the treatment of unstable and comminuted DRFs. Additional K-wires should be used to complement the fracture fixation, when there is unacceptable fragment reduction only with external fixator.
