Extensor Carpi Ulnaris Instability Following Ulnar Shortening Osteotomy

Abstract

Background Ulnar shortening osteotomy (USO) is a well-established procedure for the treatment of ulnar impaction syndrome. Although uncommon, the procedure can be associated with complications including nonunion, malunion, and hardware irritation.

Case Description We present a 56-year-old woman who developed extensor carpi ulnaris (ECU) tendon instability following an USO.

Literature Review The etiology of such a complication can be multifactorial.

Clinical Relevance The recurrence of ulnar pain following an USO should raise the suspicion of possible ECU instability within the differential diagnosis.
