To report the clinical results of opening wedge osteotomy graft in the volarly malunited distal radius.

Ten patients with volarly malunited distal radius fractures treated by opening wedge osteotomy were included in this study. Grip power, range of motion of the wrist, radiographic parameter and Mayo wrist scores were retrospectively evaluated.

At the final follow-up, the rotation of the forearm, the range of motion of wrist, and the grip power were improved. The average radial inclination improved to 22.2°, the average volar tilting improved to 5.6°, and the average ulnar variance improved to 0.8 mm. The average Mayo wrist score was improved to 85.6.

Opening wedge osteotomy for volarly malunited distal radius was considered as one of the good treatments to restore anatomy of the distal radius and distal radioulnar joint and also to improve the function of the wrist joint.
