Summary

The wrist, or carpus, is defined as distal portion of radius and ulna, carpal bones and their articulations with metacarpal bases. The hand includes structures distal to metacarpal bases, namely metacarpophalangeal joints, phalanges and their articulations. The wrist and hand are anatomically distinct from each other and radiographic evaluation of each is different. Imaging of hand trauma and wrist trauma includes radiographs, computed tomography (CT), magnetic resonance (MR) imaging and ultrasound. Both fractures of the distal radius and ulna, and scaphoid fractures result from a fall on an outstretched hand. Most carpal dislocations are related to high-energy trauma related to either motor vehicle accidents or falling from a height. Metacarpal fractures are divided into fractures of the head and neck, shaft and base, with the first and fifth metacarpals being the most commonly fractured. Carpometacarpal (CMC) dislocations most frequently occur at the thumb and the fourth and fifth CMC joint.
