Distraction Osteogenesis for Distal Radius Fractures vs. Volar Plating

Optimal fixation for highly comminuted distal radius fractures with metadiaphyseal extension remains to be a major treatment challenge for orthopaedic surgeons. The purpose of this study is to determine the safety, feasibility and sample size estimations for a larger, definitive study comparing functional outcomes of patients treated with dorsal distraction plate fixation with or without fragment specific fixation to standard open reduction internal fixation in highly comminuted distal radius fractures (subtypes AO.23-C2 and AO.23-C3). The study design will be a pilot randomized control trial. Fracture pattern eligibility will be determined by consensus agreement between two fellowship trained upper extremity specialists. The primary outcome measure will be the QuickDASH score. Secondary outcome measures include wrist range of motion, grip strength, Visual Analog Scale pain scale, Short Form SF-12, and EQ-5D. Ultimately, this study will lead to a larger randomized control trial and result in improvement in the care and treatment of patients with these challenging injuries.
