Carpal Fractures
A 28-year-old rock climber falls 5 meters, landing on his outstretched hand. He presents with diffuse wrist pain, swelling, and limited range of motion. Radiographs reveal a fracture through the waist of the capitate with minimal displacement. CT scan confirms an associated fracture through the waist of the scaphoid. On careful review of the CT, the proximal fragment of the capitate appears to be rotated 180 degrees, with its articular surface facing the fracture site rather than the lunate.
