S63.046
Dislocation of carpometacarpal joint of unspecified thumb
Clinical Classification Guidelines
Medical Intelligence & Overview
Dislocation of the carpometacarpal joint of the thumb involves the displacement of the joint where the thumb's metacarpal bone connects with the wrist bones. This injury typically results from trauma or a sudden impact, leading to pain, swelling, and limited movement in the thumb area. Proper management and timely treatment are essential to restore function and prevent long-term complications.
Causes & Symptoms
Clinical Causes: Falling onto an outstretched hand with the thumb extended or abducted Direct blow or trauma to the base of the thumb Sports injuries involving gripping or twisting motions Accidents during activities that apply excessive force to the thumb joint
Key Symptoms: Severe pain at the base of the thumb Swelling and bruising around the joint Deformity or observable misalignment of the thumb Difficulty in moving or gripping with the thumb Tenderness to touch around the joint In some cases, numbness or tingling if nerves are affected
Diagnostic & Treatment
Diagnosis Path: Diagnosis often involves a physical examination to assess the deformity, swelling, and range of motion. Imaging studies such as X-rays are essential to confirm the dislocation, determine its severity, and rule out associated fractures. Sometimes, additional imaging like MRI may be used to evaluate soft tissues if necessary.
Treatment Protocols: Reduction: A healthcare professional may realign the dislocated joint through a careful manipulation procedure, often performed under local anesthesia. Immobilization: After realignment, the thumb is typically immobilized using a splint or cast to allow the ligaments and surrounding tissues to heal. Pain management: Use of analgesics or anti-inflammatory medications to reduce discomfort. Rehabilitation: Following immobilization, physical therapy exercises help restore strength, flexibility, and function to the thumb. Surgical intervention: In cases where closed reduction is unsuccessful or if there are associated fractures, surgery may be necessary to realign bones, repair soft tissues, or stabilize the joint with pins or screws.
