Ulnar Neuropathy due to Volar/Ulnar Displacement of the Flexor Tendons after Open Carpal Tunnel Release: Case Report

Abstract

Ulnar nerve neuropathy is a rare complication following the carpal tunnel release. Above all, compression neuropathy is much rare. We report an acute ulnar nerve neuropathy following open carpal tunnel release due to the volar and ulnar displacement of the flexor tendons from the carpal tunnel and review the literature.
