Lisfranc injuries are rare, accounting for under 1% of all fractures. In 90% of cases the dislocation is combined with a fracture, while in the remaining 10% the ligaments only are affected. The injury can present in various ways. Isolated complex foot trauma is not difficult to diagnose, but in more than 20% of all Lisfranc luxations the diagnosis is missed. This is because when confronted with a multiply traumatised patient physicians concentrate on any life-threatening injuries and not on the foot, but the diagnosis of Lisfranc injury is very often missed even after low-energy trauma because the presentation is occult. In addition to the history, knowledge of the condition of the soft tissues and skill in the interpretation of X-rays and also of the results of computer tomography are necessary. The treatment of choice is open reduction and internal fixation with Kirschner wires ore single screws. Concomitant compartment syndrome is present in up to 60% of cases. Good functional results can be achieved by timely diagnosis, early internal fixation with anatomical reduction and consistent management of soft tissue.
