Traumatic dislocation of the first metatarsophalangeal joint is a rare injury. Recently Jahss described two such dislocations are proposed a classification based on pathomechanics. In this system Type-I dislocations, in which the proximal phalanx and both sesamoids dislocate dorsally without disruption of the sesamoid complex, are invariably irreducible by closed manipulation, while Type-II dislocations, in which the phalanx dislocates dorsally with disruption of the sesamoid complex, are usually reducible by manipulation. It is the purpose of this paper to report another case of Type-I dislocation of the first metatarsophalangeal joint, to describe the pathological anatomy, and to describe open reduction through a dorsal approach.
