Concomitant plantar tarsometatarsal (Lisfranc) and metatarsophalangeal joint dislocations.

We report an unusual case of concomitant plantar tarsometatarsal (Lisfranc) and 1st and 2nd metatarsophalangeal (MTP) joint dislocations and fracture of the neck of the third metatarsal bone which has never been reported before. The plantar dislocation of the Lisfranc joint was treated by open reduction and fixation with K-wires; the dislocations of the MTP joints and neck fracture of the third metatarsal bone were treated by closed reduction and percutaneous fixation with K-wires and immobilized with a plaster cast. At the 5 year follow-up examination, our patient had no complaints, but the radiograph showed degenerative changes of the Lisfranc and the 1st MTP joint.
