Aetiology
Dislocation of the other carpometacarpal joint, usually the thumb, may be caused by an injury such as a fall, a direct blow to the hand or wrist, or an unnatural twisting of the joint.
Diagnosis
A dislocation of the other carpometacarpal joint is usually diagnosed through a physical examination by a doctor. The doctor will assess the swelling, tenderness, and deformity of the joint. They may also order x-rays to confirm the diagnosis.
Differential diagnosis
Differential diagnoses include fractures, sprains, tendonitis, and nerve entrapment.
Treatment
Treatment for a dislocated other carpometacarpal joint may include immobilization in a cast or splint, anti-inflammatory medications, ice, and elevation of the affected limb. Surgery may be needed in some cases.
Prognosis
With prompt and proper treatment, prognosis is usually good. Most patients are able to return to their normal activities with minimal discomfort.
