Lunate dislocation

This 25 year old male fell while riding his motorcycle. He presented with severe pain and swelling of his wrist. There was tenderness on both the dorsal and volar aspects of his wrist. Note that on the PA radiograph the midcarpal joint space is interrupted by the lunate overlapping the capitate. On the lateral radiograph, the lunate is displaced in a volar direction from its usual position of articulation with the radius and capitate.

These injuries require emergency orthopedic or hand specialist consultation for reduction.
