Median nerve neuropathy from an old lunate dislocation.

The case of an old volar dislocation of the lunate, associated with median nerve neuropathy, is described in a 37-year-old patient. The treatment took into account the age of the patient and the relative tolerance to the dislocation. We performed a simple excision of the lunate combined with a release of the transverse carpal ligament in order to free the median nerve, together with a tenosynovectomy of flexor digitorum profoundus. Two years after operation, wrist function was virtually complete and the patient was asymptomatic and had resumed his occupation.
