Radially Based Extensor Retinacular Sling Reconstruction for Extensor Carpi Ulnaris Subsheath Injuries.

Purpose: Extensor carpi ulnaris (ECU) subsheath injuries result in ulnar-sided wrist pain and often present concurrently with intrinsic ECU pathology and ulnocarpal compartment injuries. There is a lack of surgical outcome data despite the variety of described ECU subsheath pathologies and reconstructive strategies.

Methods: We retrospectively reviewed our hand-center experience of 33 patients who prospectively underwent radially based extensor retinacular sling ECU subsheath reconstruction by 4 hand surgery-fellowship-trained surgeons between April 2010 and April 2021.
