Abstract

Anterior dislocation of lunate is rare, it can result in median nerve compression and attritional rupture of flexor tendon when delay diagnosed. We report a patient with second finger flexor tendon rupture and carpal tunnel syndrome caused by neglected anterior lunate dislocation. Patient underwent operative treatment for that excised lunate, released carpal tunnel and reconstructed second flexor tendon using palmaris longus tendon. One year after surgery, fucntional and neurologic symptom were recovered. Also carpal alignment was maintained on plain radiographs, even after excision of the lunate.
