Abstract
Fractures of the metacarpal bones are very common injuries of the
skeletal system and, in approximately 50% of the cases, involve the neck
of the fifth metacarpal bone. The Metacarpal neck fractures are among
the most common of hand fractures with those involving the fifth
metacarpal (boxer’s fractures) being the most common. These fractures
result from a longitudinal compression force acting on a flexed
metatarsophalangeal joint usually when a clenched fist strikes a solid
object, the resultant fracture is usually unstable with volar angulation due
to commination of the volar cortex and the deforming action of the
interossei.
These fractures are frequently observed in active young men, occur in the
dominant hand and are typical injuries of aggression (boxer’s
fractures).their treatment can be problematic ,many treatments are
numerous: functional treatment by a simple syndactylisation with risk of
secondary displacement;the Conservative treatment consists of a cast
immobilization, but sometimes source of skin complications, and there
are Various fixation techniques in use are: a direct osteosynthesis;
percutaneous pinning ; plating and percutaneous transverse pinning .
The management of boxer’s fracture is still Controversial, Various
operative techniques have been proposed for the surgical treatment of
these fractures,the principles of treatment include restoration of articular
anatomy, stable fixation of fractures, elimination of angular or rotational
deformity and rapid restoration of mobility and function. Although
Flexible intramedullary nailing is indicated for any displaced or unstable
fracture of the metacarpal neck.
