Locked Floating First Metatarsal: Open Reduction and no Fixation - Case Report

Almost all traumatic injuries can be classified using established criteria, but foot trauma can result in various combinations of injuries. Leibner et al. first described concomitant Lisfranc fracture-dislocation and complex dislocation of the metatarsophalangeal (MTP) joint, and coined the term ‘floating metatarsal.’ Since then several variants of floating metatarsal have been reported.2,4–7,9,10 Isolated floating metatarsal involving dislocation alone without fracture of the metatarsal is even more uncommon. We describe a case of an isolated locked floating metatarsal without fracture caused by minor trauma. In this case, the metatarsal head was button-holed and locked. The patient was treated by open reduction without fixation.
