Abstract:
We are reporting a case of traumatic dislocation of the first metatarsophalangeal joint that does not correspond to any previously reported type. This new type of dislocation was associated with a rupture of the lateral short sesamophalangeal ligament/plantar plate, partial rupture of the intersesamoid ligament, and separation of a previously bipartite tibial sesamoid. Closed reduction was easily performed; however, the distal portion of the tibial sesamoid remained trapped within the joint. The rationale for and result of surgical treatment are presented.
