Arthrodesis of a carpometacarpal (CMC) joint, specifically for digits other than the thumb, is a surgical procedure aimed at stabilizing the joint by fusing the bones together. This procedure is commonly indicated for patients suffering from conditions such as arthritis or instability in the CMC joint, which can lead to pain and functional impairment. The surgery involves making an incision over the CMC joint to access the joint capsule, where the surgeon inspects the joint surfaces. The articular cartilage, which is the smooth tissue covering the ends of bones in the joint, is removed to prepare the surfaces for fusion. The carpal bone is then reshaped to ensure a proper fit with the metacarpal base. In this procedure, an autograft is utilized, which involves harvesting bone from the patient's own body, typically from the iliac crest. This harvested bone is then shaped to fill the defect created by the removal of cartilage and is secured in place to facilitate the fusion of the joint. The procedure concludes with the repair of soft tissues in layers and the application of a short arm cast to support the healing process.
