Lisfranc fracture-dislocations of the foot: a clinical-kinesiological study.

Twenty-three patients with Lisfranc fracture dislocation of the foot were reviewed at an average of 19.4 months following injury. Results were assessed by a subjective questionnaire, physical examination, and radiographic analysis. There were 10 good (43.5%), 10 fair (43.5%), and 3 poor (13.0%) results. A subgroup of 11 patients underwent gait analysis in the pathokinesiology laboratory. No patient had a normal gait following a displaced Lisfrance fracture. Limp was thought to be due to a prolonged hindfoot period, and a delayed and shortened period of weight transfer through the midfoot to the forefoot as a result of pain inhibition. The best results both clinically and by gait analysis were achieved in those patients who had anatomic reductions.
