![]() ![]() Young men sustain metacarpal fractures secondary to a punching mechanism or a direct blow to the hand Men are more likely to be affected than women. Typically occur in patients aged 10-40 years Makeup about 40% of all acute hand injuriesĬonstitute about 20% of all fractures occurring below the elbow Work-related injuries are often the cause in middle-aged patientsįalls are typically the cause of the elderly.įifth metacarpal fractures often occur secondary to punching a wall or other solid object (hence the eponym, "boxer's fracture") Sporting injury is frequently the cause among younger patients ![]() Almost one-fourth of cases occur during athletic events. These fractures commonly occur during athletic activities, particularly in contact sports. Metacarpal fractures typically occur secondary to a direct blow or fall directly onto the hand. With severe polytrauma cases, the tendons and nerves adjacent to the fracture can also be injured. Soft tissues generally involved with fractures include cartilage, joint capsule, ligaments, fascia, and the dorsal hood fibers. The 3rd metacarpal is distinguished by a styloid process on the lateral side of its base. The 1st metacarpal is the thickest and shortest of these bones. ![]() The proximal bases of the metacarpals articulate with the carpal bones,ĭistal heads of the metacarpals articulate with the proximal phalanges and form the knuckles. Įach is comprised of a base, shaft, and head. The metacarpals are long, thin bones that are located between the carpal bones in the wrist and the phalanges in the digits. The mechanisms of these injuries vary from axial loading forces to direct blows to the dorsal hand Is a break in one of the five metacarpal bones of either hand.Īre categorized as being fractures of the head, neck, shaft, and base (from distal at the metacarpal phalangeal joint to proximalīoxer fracture is another name for a fracture of the fourth or fifth metacarpal, one of the most common metacarpal fractures.
