A Case Series of Functional and Radiological Outcome of Comminuted Distal Radius Fractures Treated with Bridging...

Comminuted intra-articular distal radius fractures are complex injuries often resulting from high-energy trauma, requiring precise reduction and stable fixation. Spanning external fixation, with optional K-wire augmentation, has emerged as a minimally invasive technique offering reliable stabilization through ligamentotaxis while reducing operative time, blood loss, and infection risks.

This case series evaluated patients with AO Type C3 distal radius fractures treated using spanning external fixators with optional K-wire supplementation. Functional outcomes were assessed using the disabilities of arm, shoulder, and hand score, and radiological outcomes were evaluated using the Sarmiento radiological score over a 1-year follow-up period. Almost all patients achieved excellent results on both scoring systems, with minimal complications and no significant functional limitations reported.

Spanning external fixation, with or without K-wire support, is an effective alternative to open reduction methods for complex intra-articular distal radius fractures. It offers the advantages of simplicity, reduced operative duration, less blood loss, and a lower risk of infection, making it a reliable option for managing these challenging injuries.
