Luxação divergente da articulação carpometacárpica: relato de caso / Divergent carpometacarpal dislocation: case report

ABSTRACT

It is reported a case of hand injury with divergent carpometacarpal dislocation in which the 5th metacarpal was palmarly displaced, and 2nd, 3rd and 4th were dorsally displaced. The authors make considerations about anatomy, mechanism of injury, diagnosis and treatment. The divergent dislocation of the carpometacarpal joints is very rare; only related by Gunther in 1985, and recently by Busa in 1998, in accordance with literature revision of the last 15 years.
