The treatment methods of volar lunate dislocation and dorsal perilunar dislocation were introduced variably. We treated 7 cases of volar lunate and dorsal perilunar dislocation by closed reduction and K-wire fixation, open reduction and isolated lunate excision. The 1 case of trans-scaphoid dorsal perilunar dislocation was treated by closed reduction and Herbert screw fixation.

The result were as followed:

1. The early diagnosis and early treatment is the most improtant.

2. The closed reduction and percutaneous pinning has advatage of maintenance of reduction and stability of wrist joint.

3. The advantage of Herbert screw fixation is anatomical reduction of the scaphoid fracture but disadvantage is technical difficulty.

4. In open reduction, we must choose the approach that minimiBe the vascular damage to the lunate from the volar side.

5. The isolated lunate excision is not advised.
