Closed Traumatic Zone 2 Flexor Tendon Injury of the Long Finger - A Case Report

Abstract

Closed rupture of the flexor digitorum profundus (FDP) tendon causes loss of flexion at the distal interphalangeal joint. Following trauma, these are known to present as avulsion fractures (Jersey finger) commonly in ring fingers. Traumatic tendon ruptures at the other flexor zones are seldom noted and are often missed. In this report, we present a rare case of closed traumatic tendon rupture of the long finger FDP at zone 2. Though it was missed initially, was confirmed with Magnetic Resonance Imaging and underwent successful reconstruction using an ipsilateral palmaris longus graft. Level of Evidence: Level V (Therapeutic).
