Neglected Volar Lunate Dislocation - A Case Report

Volar lunate dislocation is an uncommon injury and may be missed in diagnosis. We reported a 44-year-old male patient who had persisten pain and limited rang of motion in the right wrist associated with a numbness sensation in the index and middle finger after a traffic accident 7 months prior to consultation. An initial X-ray was taken in another hospital where no fracture or dislocation was found. He has been treated for cervical radiculopathy since then. Volar lunate dislocation was diagnosed by our senior surgeon with the help of the X-ray and computerized tomography. Carpal tunnel syndrome was made sure by the examination of nerve conduction velocity. Combine dorsal and palmar approach to reduce the dislocated lunate was used. Four Kirschner-wires were inserted percutaneously to keep the lunate in normal position. Median nerve decompression and intercarpal ligaments repair were performed at the same time. Postoperatively a long arm splint with the wrist in a neutral position was used for 4 weeks, then a short arm splint for another 4 weeks. The intercarpal pins were removed in 8 weeks after the operation. This patient had regular follow up visits for more than one year. He exhibited no pain in the right wrist and returned to work with a little loss of motion in the wrist.
