Dislocation of the First Metatarsophalangeal Joint: A Case Report and Suggested Classification System.

Dislocation of the first metatarsophalangeal joint is a relatively rare and still poorly known injury. The current classification includes only the dorsal variety of this lesion; thus, as further cases of other varieties are reported, a larger understanding of this entity is required. We report the case of a young male with dorsal dislocation of the first metatarsophalangeal joint treated by closed reduction. The clinical outcome at the 2-year follow-up point is reported. A review of the published data of the variations of this injury reported to date is included, and a new summarizing classification is suggested.
