Objectives: To describe the long-term follow-up results of complex dorsal metacarpophalangeal joint dislocation (CDMPJD) with a literature review concerning complications. We hypothesize that there would be no long-term disability in most patients, even with the presence of one of the familiar complications.

Methods: We describe five patients with a mean follow-up of 20.4 years and 12 manuscripts with descriptions of follow-up or complications.

Results: Complications in patients with CDMPJD are related to failure of diagnosis, repeated attempts at closed reduction, traumatic open reduction or prolonged immobilization, and may result in joint stiffness, early degenerative arthritis or osteonecrosis of the metacarpal head, pain, premature epiphysis closure and metacarpal shortening.

Conclusions: The overall findings sugest that CDMPJD treated on arrival with one of the familiar open reduction techniques will eventually result with no functional deficit or pain, even with one of the complications mentioned.
