1) Patients with wrist disorder* due to articular incongruity** caused by malunited intra-articular fracture of the distal radius
(*: One or more of the following symptoms or findings; restricted range of joint motion, pain, pre- or early stage osteoarthritis on plain radiograph)
(**: 2.0 mm or more joint surface step-off on CT image)

3) Patients 18 years or older and 75 years or younger at the time of obtaining consent (both male and female)
4) Patients for whom written consent has been obtained
1) Patients who were diagnosed to be unsuitable for intra-articular corrective osteotomy due to deformity associated with severe crushing and complicated external joint fracture
2) Patients who have advanced to end-stage osteoarthritis in the target joint and are diagnosed not to be eligible for intra-articular corrective osteotomy
3) Patients who are not suitable for general anesthesia or regional transmission anesthesia
4) Patients with active malignancy
