NC54.1/S63 Dislocation of thumb



Dislocation of the thumb is usually caused by a sudden trauma, such as a fall, or a direct blow to the thumb. It can also be caused by repetitive strain or overuse of the thumb.


Diagnosis of a dislocated thumb is usually made with a physical examination. The doctor will look for signs of swelling, deformity, or tenderness. X-rays may also be taken to confirm the diagnosis and rule out any potential fractures.

Differential diagnosis

Differential diagnosis for a dislocated thumb includes fractures, joint sprains and strains, tendonitis, and other joint injuries.


Treatment for a dislocated thumb includes immobilization with a splint or cast, pain medications, and physical therapy. In some cases, surgery may be necessary to realign the thumb.


The prognosis for a dislocated thumb is generally good. With proper treatment, the thumb should regain full range of motion and strength.
