Dislocation of the metatarsophalangeal joint is rare due to the stability of the ligaments and soft tissue surrounding the joint. The authors have experienced lateral dislocation of the first metatarsophalangeal joint, which required surgery, accompanied by complete injuries of medial collateral ligament and capsule, contributing to medial stability, differing from posterior dislocation with intersesamoid complex rupture, with a review of the relevant literature and previous reported cases.

Dislocation of first metatarsophalangeal joint is a rare condition. Anatomically, the head of first metatarsal is stabilized by various soft tissue structures associated with the sesamoid bones. When the metatarsal head was entrapped underneath the sesamoid complex, it might be impossible to gain reduction via closed method.
We experienced a case of dorsal dislocation of first metatarsophalangeal joint and associated dislocation of larsornetatarsal joint in a 32 year old man who was injured by ftll from height. Closed reduction fEiled even under spinal anesthesia. Open reduction via medial approach revealedbuttonholingof the metatarsal head under the sesamoid complex, which had made colsed reduction impossible. Concerning about the rarity and anatomical characteristic of these injuries, we report this case with reviewing of the literatures.
