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

Abstract

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