Arthroscopic-assisted Distal Radius Fracture Fixation for Dorsoulnar Corner Fragments Using a Locked, Hooked Kirschner-Wire Technique
Abstract Background: Distal radius fractures with dorso-ulnar corner fragments (DUC) pose a surgical challenge due to limited visualization and the risk of hardware prominence. Traditional approaches often result in inadequate reduction and fixation, leading to suboptimal clinical outcomes. Description of Technique: In this study, we introduce an arthroscopic-assisted approach for the fixation of distal radius fractures with DUC fragments. The technique utilizes locked, hooked K-wires to provide a low-profile dorsal capturing mechanism. We outline the step-by-step procedure, which includes pre-operative planning, volar plate application, and arthroscopic reduction of DUC fragments. Patients and Methods: We applied this technique to a 60-year-old female patient with an unstable intra-articular distal radius fracture and a DUC fragment. Closed reduction was initially attempted, followed by arthroscopic-assisted reduction and internal fixation using the locked, hooked K-wire technique. Results: Our technique has demonstrated its ability to withstand early movement rehabilitation protocols without fixation loss, enabling early mobilization. A custom thermoplastic splint was worn for 6 weeks, with favorable supination/pronation and wrist flexion/extension outcomes at clinical review. Conclusions: Arthroscopic-assisted fixation with locked, hooked K-wires offers a reliable solution for accurately reducing challenging DUC fragments in distal radius fractures. This approach complements standard distal radius fixation systems, providing a low-profile dorsal capturing mechanism and addressing the issue of hardware prominence, ultimately improving clinical outcomes.
