The aetiology, treatment and outcome of Lisfranc joint dislocations and fracture dislocations (L) were analysed. From 1972–97, 101 L were treated (right: n = 52, left: n = 49, bilateral: n = 8). Pure joint dislocations (LD) were observed in 24 cases, fracture dislocations (LFD) in 55 cases and Chopart-Lisfranc fracture dislocations (CLFD) in 22 cases. A total of 85 L were operatively treated; 15 times with closed reduction and 70 times with open reduction. A total of 85 (84%) feet received internal fixation, and in 15 (15%) cases, an external fixator was utilized additionally. In total, 10 primary and 20 secondary arthrodeses were performed and 16 feet were treated non-operatively. A total of 62 patients had follow-up after 9 (1–25) years. The mean scores were: AOFAS-Midfoot = 72 (29–100), Hannover Scoring System = 66 (26–100). Under consideration of age, sex, injury cause, time and type of treatment, no significant score differences occurred. CLFD showed lower scores than LD and LFD. In LFD and CLFD, an initial and maintained anatomic reduction with internal fixation or added external fixation was essential for good results. The long-term results of L are characterized by high functional restrictions, which can most likely be minimized with early open reduction and internal fixation, especially in fracture dislocations.
