Metacarpal Neck Fracture

A metacarpal neck fracture is a break in the bone just below the knuckle in one of the hand's long bones called metacarpals. This injury affects the skeletal system, specifically the bones of the hand, and can cause pain, swelling, and difficulty moving the fingers. It often results from a direct blow or punching an object, leading to a bent or shortened finger appearance. The fracture mainly impacts hand function, making gripping and fine motor tasks challenging. Early recognition and proper care are important to restore normal hand movement and strength.

Metacarpal neck fracture refers to a break occurring at the narrow region just distal to the metacarpal head, commonly involving the fifth metacarpal (known as a boxer's fracture). The injury typically results from axial loading or direct trauma, such as punching a hard surface. This fracture causes angulation and possible shortening of the metacarpal, leading to impaired hand mechanics and decreased grip strength. Clinically, patients present with localized tenderness, swelling, and limited finger motion. Radiographically, the fracture is identified by disruption of the cortical bone with characteristic dorsal angulation. The condition is significant due to potential complications like malunion and reduced hand function if untreated.
