Isolated Fracture-Dislocation of Fourth Metacarpal Bone with Hamate Body Fracture

Abstract

Hamate body fracture is so rare that it is sometimes difficult to diagnose. We treated a patient who punched a pillar with his clenched fist and sustained a fourth carpometacarpal joint fracture-dislocation with hamate body fracture. Plain lateral x-ray and plain CT films were useful for the diagnosis. Treatment with open reduction and internal fixation with compression screw achieved excellent clinical results.
