#Metacarpal fracture plus
The hand should be positioned in the intrinsic plus position for splinting: mild wrist extension, 70 to 90 degrees of flexion at MCP joint, and slight flexion at the DIP and PIP joints. Alternatively, a pre-made Galveston splint or a custom orthosis may be used. A Boxer’s fracture should be immobilized with an ulnar gutter splint. Due to the risk of infection from "fight bite," even very small wounds should be thoroughly irrigated, and there should be a low threshold for antibiotic treatment.įor a Boxer’s fracture that is closed, not angulated, and not malrotated or otherwise displaced, splinting is used for initial immobilization. The appropriate treatment for a Boxer’s fracture on initial presentation varies based on whether the fracture is open or closed, the degree of angulation, rotation, and other concomitant injuries. The arteries and nerves supplying the fingers are adjacent to the metacarpal bones and can be injured in severely displaced Boxer’s fractures, requiring surgical intervention. The ligaments are taut in flexion, and more slack in extension, therefore the MCP joints should be splinted in flexion to prevent shortening (intrinsic plus positioning). The collateral ligaments also join the metacarpal bones to the proximal phalanges and must be taken into consideration during splinting to minimize the risk of loss of motion due to shortening of the ligaments.
The interosseous muscles, responsible for adduction and abduction of the fingers, originate from the metacarpal shafts and insert onto proximal phalanges. Axial load via direct trauma to a clenched fist transfers energy to the metacarpal bone, causing fractures most commonly at the neck, and typically resulting in apex dorsal angulation due in part to the forces exerted by the pull of the interosseous muscles. The metacarpal bone consists of a head (distally located), neck, body, and base (proximally located). The fifth metacarpal is associated with the fifth digit.
