What Is a Boxer’s Fracture?
A boxer’s fracture is a break in the bone below the pinky finger. The injury affects the fifth metacarpal, one of the long bones in the hand that helps support movement and grip strength.
This type of fracture often happens when a closed fist strikes a hard surface. Although it’s common in boxing and contact sports, anyone can experience this injury after direct trauma to the hand.
Symptoms
A boxer’s fracture can cause pain and make everyday hand movements difficult. Symptoms may appear immediately after the injury.
Common symptoms include:
- Pain along the outer side of the hand
- Swelling or bruising
- Tenderness near the pinky finger
- Trouble moving the fingers or making a fist
- Weak grip strength
- A knuckle that looks flattened or out of place
- Finger misalignment
How Is It Diagnosed?
A healthcare provider will examine your hand for swelling, tenderness, finger alignment, and range of motion. They will also ask how the injury happened and whether you can move your fingers normally.
X-rays are usually used to confirm the fracture and determine whether the bones are still properly aligned. Imaging also helps providers decide the best treatment approach.
How Is It Treated?
Many boxer’s fractures can heal without surgery. Treatment often begins with rest, ice, elevation, pain management, and wearing a splint or cast to keep the hand stable while the bone heals.
If the bones have shifted out of position, a provider may need to gently move them back into alignment before splinting the hand. Physical or occupational therapy may help improve strength, flexibility, and movement during recovery.
More serious fractures may require surgery, especially if the bone is severely displaced, broken in multiple places, or has pushed through the skin.
Most people begin to heal within several weeks, although stiffness and weakness can take longer to improve. Following your treatment plan carefully can help support a smoother recovery.
