Bennett's Fracture

Bennett's fracture is a fracture of the metacarpal bone in the thumb. Often, displacement occurs at the fracture site, causing the metacarpal bone to be pulled out of position. Such displacements are often caused by an impact to a slightly bent thumb, such as a blow with a clenched fist.

Symptoms

Pain, swelling, and tenderness around the thumb extending toward the wrist, as well as reduced ability to move the thumb.

Diagnosis

An X-ray can confirm a suspected fracture. In some cases, a CT scan may be performed to determine the extent of joint displacement.

Treatment

The fracture is treated surgically, followed by casting and then gradual rehabilitation.

Prognosis

The cast and pins from the surgery are removed after 5 weeks, and the athlete can then begin gradual rehabilitation of the hand. In total, it will take approximately 3 months before boxing can be resumed following the injury.
