Introduction: The term ‘Lisfranc lesion’ broadly refers to a set of poorly defined lesions mainly affecting the tarsometatarsal joint complex. It involves partial damage or complete loss of joint congruity of the tarsometatarsal joint, with or without fractures. These injuries are considered to account for only 0.2% of all fractures of the musculoskeletal system. The aim of this study is to evaluate the epidemiological, diagnostic, therapeutic and evolutionary aspects of tarsometatarsal dislocations.

Patients and methods: This is a retrospective descriptive study conducted in the Orthopedics and Traumatology Department of the Dalal Jamm National Hospital Centre in Guédiawaye over a period of 28 months from September 2022 to December 2024.

Results: Out of a total of twelve (12) patients, seven (07) met our inclusion criteria. These included five men and two women. The average age of our patients was 33.14 years, ranging from 20 to 57 years. In terms of occupation, workers in the informal sector were the most represented (four cases). Road traffic accidents were the most common (5 cases), followed by accidents on public roads (1 case) and accidents at work (1 case). The mechanism was most often direct (4 cases) by compression. The diagnosis was based on clinical and paraclinical data. Treatment was surgical in 85.7% of cases (n = 6) and orthopedic with a circular plaster cast in one patient due to lack of resources. The foot assessment score was good in five patients and poor in one patient on day 21 post-operatively. Two cases of suppuration were noted, one of which was treated by debridement and the other by debridement and removal of the pins on postoperative day 45.

At a mean follow-up of 18.2 months, a functional assessment using the modified Wiener score was performed, with a satisfactory score for 5 patients.

Conclusion: The Lisfranc tarsometatarsal joint plays a key role in the stability of the midfoot, and its anatomical restoration through proper reduction and stable immobilization is necessary to ensure optimal functionality and painlessness of the foot.
