[edit | edit source]
The five metacarpal bones form the skeleton of the palm of the hand between the carpal bones and the phalanges. Each are comprised of a base, shaft, and head. The proximal bases of the metacarpals articulate with the carpal bones, and the distal heads of the metacarpals articulate with the proximal phalanges and form the knuckles. The 1st metacarpal (of the thumb) is the thickest and shortest of these bones. The 3rd metacarpal is distinguished by a styloid process on the lateral side of its base. Soft tissues generally involved with fractures include cartilage, joint capsule, ligaments, fascia, and the dorsal hood fibers. With severe polytrauma cases, the tendons and nerves adjacent to the fracture can also be injured1.
