Irreducible Dorsal Metacarpophalangeal Dislocation of the Thumb: A Case Report and Literature Review

Dorsal dislocations of the metacarpophalangeal joint of the thumb are rare. Complex dorsal dislocations are defined by the entrapment of the sesamoid bones and the soft tissue, such as the volar plate, behind the phalanx at the level of the metacarpal neck. These cases often necessitate open reduction. We present the case of a 22-year-old male patient who was admitted to our institution with a dorsal metacarpophalangeal dislocation of the thumb. Surgical reduction was required following the failure of closed reduction attempts.
