Inclusion criteria

Inclusion criteria: Patients who agreed to join this study among patients with extensor tendon ruptures due to distal radioulnar joint lesion.

Exclusion criteria

Exclusion criteria: Patients with rheumatoid arthritis lesion classified as Larsen grade III or IV at the distal radioulnar joint. Patients with rheumatoid arthritis and with apparent swelling or tenderness at the radiocarpal, carpometacarpal, or interphalangeal joints.
