Boxer’s Fracture

A boxer’s fracture is a break in the metacarpal (bones that connect the fingers to the wrist) of the little finger. It has this name because the injury is common in inexperienced boxers, although anyone can get a boxer’s fracture. Most boxer’s fractures result in direct injury to a clenched fist.

Causes

Boxer’s fractures most commonly occur from punching a hard surface or another person with a closed fist. This injury can also occur from falling hard on a closed fist. The neck of the metacarpal bone is its weakest point and is prone to fractures.

Symptoms

Symptoms of boxer’s fractures include bruising or swelling at the back of the hand, pain in the little finger, a little finger that looks out of alignment, and limited motion in this part of the hand.

Diagnosis

Physicians will ask about symptoms and examine the hand for pain, strength, misalignment, and range of motion. X-rays may also be used to confirm a boxer’s fracture.

Treatment

Most boxer’s fractures are treated with a cast or brace to stabilize the fracture as it heals. Surgery may be required in severe cases. Physical therapy can also be used to strengthen the muscles in the hand.
