The investigators conduced a clinical trial to evaluate the clinical and radiographic results after radioscapholunate fusion in case of posttraumatic radiocarpal osteoarthritis.

Because of poor clinical result, many authors upgrade the procedure including excision of the distal pole of the scaphoid and later excision of the entire triquetrum.

Only one study compared the three procedures in 17 patients. The investigators performed the same comparison in 85 patients with a mean follow up of 9,1 years (1-23)

The investigators compared three populations: patients with radioscapholunate (RSL) fusion alone, patients with RSLfusion and distal scaphoid excision and patient with RSL fusion, distal scaphoid excision and excision of the triquetrum.

The investigators performed clinical (pain, grasp strength, wrist motion), functional and radiographic (midcarpal osteoarthritis and radiocarpal nonunions) evaluation

Inclusion criteria:

• posttraumatic radiocarpal osteoarthritis

Exclusion criteria:

• Patients with radiocarpal osteoarthritis due to rheumatoid or inflammatory disease and Kienböck disease
• Patients with posttraumatic radiocarpal osteoarthritis managed with other surgery

Patients who had posttraumatic radiocarpal osteoarthritis and underwent RSL fusion
