Abstract:
Ulnar dysmelia is a congenital anatomic disorder characterized by abnormal development of the ulna and subsequent distal bones. This rare disorder has a heterogeneous presentation in patients described in the literature. We present the case of a 23-year-old woman with ulnar dysmelia who lacked the ulnar attachments of the transverse carpal ligament and developed carpal tunnel syndrome at a relatively young age, requiring carpal tunnel release. This case report presents an interesting and unique cause of carpal tunnel syndrome and reviews the literature on ulnar dysmelia.
