Treatment of extra-articular distal radius fractures using an intramedullary nail

Abstract

BackgroundDistal radius fractures are a common fracture type, but an optimal surgical recommendation remains elusive. Intramedullary fixation is a novel technique for treatment of distal radius fractures. The present study aimed to evaluate the clinical results in the management of extra-articular fractures of the distal radius using the intramedullary nail device. MethodsFrom June 2009 to July 2010, 12 patients with extra-articular fractures of the distal radius were included. Surgical reduction and internal fixation with an intramedullary nail, the Micronail, was performed primarily for treatment of five AO Type A2 and seven AO Type A3 distal radius fractures. All patients were followed up radiographically and clinically for an average of 48.5 weeks. ResultsAll fractures achieved bone union without major complication. The functional results according to the Mayo wrist scoring system were excellent in six patients, good in two patients, and fair in four patients (4/12). The mean score was 84, and the satisfactory functional result was 75%. ConclusionSurgical reduction and internal fixation with the intramedullary nail is a useful and effective technique in the management of extra-articular fractures of the distal radius.
