Knuckle Fracture

Knuckle Fracture: Causes, Symptoms, and Treatment

A knuckle fracture is a break in one of the bones that form the joints of the fingers, most often the metacarpal bones that connect the fingers to the wrist. These injuries are common in falls, sports, direct blows to the hand, or accidents involving tools or machinery. The fifth metacarpal, near the pinky finger, is especially prone to injury and is often referred to as a “boxer’s fracture.”

Symptoms of a knuckle fracture include pain, swelling, bruising, and difficulty bending the fingers or forming a fist. The hand may appear misshapen, and there may be tenderness over the affected bone. In some cases, the skin may be cut or split, especially if the injury was caused by punching or striking a hard object.

Diagnosis is made through a physical exam and confirmed with X-rays to determine the location and severity of the fracture. Treatment depends on whether the bone is displaced or stable. Many knuckle fractures can be treated with splinting or casting. Displaced or unstable fractures may require surgery to realign and secure the bones using pins, screws, or plates.

Recovery can take several weeks, and hand therapy may be recommended to restore motion and strength. With proper care, most patients regain full function. Slocum’s orthopedic team provides expert care for hand fractures to support safe healing and return to activity.
