Lisfranc dislocations and fracture dislocations are the most common severe injuries of the foot.
Aim: To assess the function-al outcome of patients with Lisfranc dislocations of the midfoot by applying the latest methods of diagnosis and treatment.
Material and methods: The study reviewed 31 patients with dislocations and fracture- dislocations of the Lisfranc joint over a 10 years period. The average follow-up period was 44 months (range 12 - 108). Injuries were classified according to Myerson scale.
Results: The outcomes were evaluated using the Baltimore Painful Foot score (PFS) and American Orthopaedic Foot and Ankle Society (AOFAS) mid-foot scoring scale. 10 patients had an excellent outcome on the PFS scale, 8 were classified as good, 13 fair and poor. The average AOFAS score for the midfoot, used for results interpretation was 72 (range 52-92).
Conclusions: Of all methods of surgical treatment used, the highest scores were obtained by inter- nal fixation with screws. Eight patients (25.8 %) developed posttraumatic arthritis of the tarsometatarsal joints.
