Symptoms and Signs of Boxer's Fracture

Doctor's Notes on Boxer's Fracture

A boxer's fracture is a break through the bones of the hand that form the knuckles. Boxer's fractures are breaks of the metacarpal bones that connect the ring finger or the little finger to the wrist. Sometimes, breaks in the neck of the second and third metacarpal bones are also included in the definition of a boxer's fracture. This type of fracture is caused by delivering a blow with a closed fist.

Signs and symptoms of a Boxer's fracture include pain that can be severe along with tenderness over the area of the fracture. Other associated symptoms can include swelling, bruising of the overlying skin, deformity or misalignment of the bones of the hand, or an abnormal movement of the broken bone fragments.
