Simultaneous Dislocation of the Interphalangeal Joint of the Thumb and the Carpal Lunate

Simultaneous quadruple dislocations of the hand in a motorcyclist: A case report

“…However this term shouldn't be confused with floating thumb which refers to thumb hypoplasia. There is also a report of simultaneous dislocation of IP joint and lunate in the literature [ 4 ], however, a simultaneous quadruple dislocation of hand seems quite peculiar.…”

“…Yet, dislocation of the carpal joints and finger joints together is extremely rare. As the matter of fact, there is only one case report of concomittant interphalangeal joint of the thumb and lunate dislocation dating back to 1987 [ 4 ]. To our knowledge, this is the first report of quadruple dislocation of the hand including dislocations in the thumb interphalangeal (IP), 1st metacarpophalangeal (MCP), and carpometacarpal (CMC) joint, and perilunate dislocation.…”
