LATE PRESENTATION OF IR-REDUCIBLE COMPLEX DORSAL DISLOCATION OF THE METACARPOPHALANGEAL JOINT OF THE THUMB

Dorsal dislocation of the metacarpophalangeal joint of the thumb is uncommon.complex dislocations occur most commonly in index finger followed in incidence by thumb & small finger &, rarely, long & ring fingers.Complex dislocations are described as dislocations that are irreducible ,infolding of the proximally disrupted volar plate between metacarpal head and base of proximal phalanxand often require surgical intervention because the thumb MP joint, anatomical structures that may become entrapped include the volar plate, sesamoid bones, bony fracture fragments or the flexor pollicislongus tendon. A case report on the post traumatic , complete complex dorsal dislocation the thumb is surgically treated on volar approach is presented .
