Single Incision, Dual Window Approach for a Comminuted Distal Radius Fracture

Abstract

Introduction Complex distal radius fractures often involve a fragment of the volar-ulnar articular surface and the radial styloid. The volar ulnar corner of the distal radius is an important constraint to volar translation of the carpus and thus requires stable fixation to prevent wrist displacement. The traditional volar Henry approach often requires undue tension on the median nerve while retracting for access to the ulnar aspect of the radius. To protect the median nerve from iatrogenic injury and to improve exposure of the surgical site, we propose a single incision, dual window approach to the distal radius for complex bi-columnar fractures.

Methods This technique combines the trans-Flexor Carpi Radialis (FCR) approach with a subcutaneous dissection to the ulnar aspect of the wrist. This window utilizes the interval between the ulnar neurovascular bundle and the carpal tunnel contents.

Results This technique allows the surgeon to work through either window and thus visualize and directly fixate the various fracture fragments. We have treated complex articular distal radius fractures associated with ulnar communition with this novel technique and it has provided direct reduction with improved fragment access. The surgical technique, a case presentation and results are detailed in this report.

Conclusion This case report has demonstrated that complex bi-columnar fractures of the distal radius can be effectively approached and fixated with a single incision dual window approach.
