Scaphotrapeziotrapezoid (STT) joint osteoarthritis is less known than other types of wrist arthritis. This disease accounts for only 13% of all wrist arthritis sites. Isolated lesions of this joint are rare and their therapeutic management is complex. The only treatment proposed used to be STT arthrodesis, a technically difficult procedure which caused numerous complications. Pseudoarthrosis is common, and STT arthrodesis has been incriminated in the occurrence of radioscaphoid osteoarthritis. Techniques of distal resection combined with interposition of biological tissues such as tendons (flexor carpi radialis) was described in the 1990s. In this video, we present arthroscopic interposition of pyrocarbon implant, a safe and convenient technique for patients, with long-lasting favorable results.
