Chronic lunate dislocations are very rare injuries comprising of less than 10% of all wrist injuries. Volar lunate dislocations account for less than 3% of perilunate dislocations. We present a case of a missed volar lunate dislocation for 6months after initial injury. He fell down and had hyperextension injury during his sports activity. When the patient visit in our hospital, neurologic symptom was developed in distribution of median nerve. Tingling sensation and radiation symptom was found in affected hand. A plain radiograph revealed a volar lunate dislocation. Nerve conduction studies confirmed compression of the median nerve at the wrist, carpal tunnel level. Operation was performed with open reduction of lunate, fixation with K-wires and anchor suture. The outcome was excellent in relieving pain, function, range of motion, grip strength. There was improvement in Mayo wrist score and disabilities of the arm, shoulder and hand score. So we report a patient and a operation technique which can be considered in similar cases.
