First metatarsophalangeal joint dislocation with open fracture of tibial and fibular sesamoids.

Traumatic dislocations of the first metatarsophalangeal joint were first described by Mouchet in 1931. The anatomical complexity of the first metatarsophalangeal joint makes this injury one of a kind. There have been only been a limited number of case reports of this injury, but none in combination with open fractures of both sesamoids. We would like to report 1 case of an open traumatic dislocation of the first metatarsophalangeal joint with open fracture of the fibular and tibial sesamoid. Open reduction and internal fixation of the injury led to a successful outcome.
