A reverse Bennett fracture-dislocation is a fracture-dislocation of the base of the 5th metacarpal bone. It is pathologically and radiographically analogous to the Bennett fracture of the thumb. It is quite unstable due to unopposed extensor carpi ulnaris pull on the fracture fragment, which causes migration and subluxation of the fragment. It is the most common base of metacarpal fracture 3.
Treatment and prognosis
This fracture frequently needs K-wire stabilization to counteract the strong force of the extensor carpi ulnaris.
