["Floating fifth metacarpal". A Case report]

We present the case of a patient with a fracture-dislocation of the fifth metacarpal and a dislocation of the metacarpophalangeal joint (floating fifth metacarpal) combined with a fracture of the fourth metacarpal. The mechanism of injury and management of this uncommon injury is reported. The "floating fifth metacarpal" and the fourth metacarpal fracture were reduced by closed techniques with percutaneous fixation. Twelve months later, the patient had a full range of wrist and finger movement, he was pain-free and without any residual disability.
