Extensor Tendon Rupture After Distal Ulna Resection: A Multicenter Case Series

Abstract

Background:

The Darrach procedure, comprising distal ulna resection, has been used to treat numerous wrist and distal radioulnar joint pathologies. Extensor tendon rupture from the proximal ulnar stump is a recognized, but lesser known postoperative complication. We present this case series of extensor tendon ruptures following Darrach procedures and their subsequent reconstructions to share different surgeon experiences with this complication.

Methods:

Patients with extensor tendon rupture after Darrach procedure were identified from contributing hand surgeon case logs. The treating surgeons shared demographic data and surgical case details pertinent to this study. A single patient experience is presented as the representative case, with the remaining patient experiences summarized in a table.

Results:

Seven patients were included. Nearly all patients underwent intraoperative capsular closure following distal ulna resection, and their extensor tendon ruptures were treated with revision surgeries.

Conclusion:

While rarely reported in the literature, treating surgeons should be aware of extensor tendon rupture as a possible complication after Darrach procedure.
