Abstract
Hand is considered one of the most commonly injured parts of the body.Fractures of the metacarpal bones are common injuries of the skeletal system and about 50% of the cases involve the neck of the fifth metacarpal bone. These fractures commonly occur in active young men, especially in the dominant hand and they are typical injuries of aggression (boxer’s fracture).Most of these fractures can be managed conservatively in splint if the fracture is not displaced or minimally displaced.However, the more displaced fractures with rotational deformity or shortening usually require operative management to correct the volar angulation, rotation and shortening of the distal fragment.Many operative techniques have been anticipated for the surgical treatment of these fractures such as intramedullary nails, k wires, cerclage wires, plating, tension band wires, lag screws and/or external fixators.The principles of treatment comprise restoration of articular anatomy, stable and rigid fixation of fractures, correction of angular or rotational deformity and rapid return to mobility and function.Intramedullary nailing is considered for any displaced or unstable fracture of the metacarpal neck.The technique is simple, with less soft tissue dissection, avoidance of periosteal stripping and good periosteal callus is generated that encourage good fracture healing.
