Dislocation of the carpometacarpal joint is usually not self-healing and requires timely repositioning in a formal institution, followed by immobilization and rehabilitation. The carpometacarpal joint consists of the distal carpal bone and the base of the metacarpal bone. When dislocation occurs due to traumatic injury or other factors, the dislocated joint cannot return to its normal anatomical structure on its own, so it usually cannot be healed on its own and needs to undergo X-ray examination in a timely manner. If there is no surrounding soft tissue damage, it can usually be repositioned by the doctor, but if there is a ligament rupture or fracture, surgery is usually required. Once dislocation of the carpometacarpal joint occurs, the patient needs to be reset in time, so as not to affect the function of the carpal joint, the patient needs to pay attention to the protection of the carpometacarpal joint after reset, to avoid re-injury of the joint, and also need to actively carry out rehabilitation training.
