Fixation of distal radial epiphyseal fracture: Comparison of K-wire and prebent intramedullary nail

Abstract

Objective: To compare the use of crossed K-wire and prebent intramedullary nail techniques for the fixation of distal radius metaphyseal fracture in children. Methods: Intraoperative and follow-up data for children with distal radius metaphyseal fracture, treated using crossed K-wire or prebent intramedullary nail fixation, were retrospectively analysed. Patient groups were matched for age, sex and clinical parameters (fracture location, affected side, fracture type). Results: Patients treated using prebent intramedullary nail fixation (n = 52) had significantly shorter surgery duration, fewer intraoperative X-radiographs, and lower prevalence of postoperative redisplacement and malalignment deformity than those treated using crossed K-wire fixation (n = 52). Both techniques resulted in similar postoperative complications and recovery of forearm rotation. Conclusions: Prebent intramedullary nail fixation has a better functional outcome than crossed K-wire fixation in the treatment of distal radial epiphyseal fracture in children.
