Fracture-Dislocations of Lisfranc Joint in Lomé (Togo)

Introduction: The purpose of this prospective study was to describe the clinic pathological varieties of fracture-dislocations of Lisfranc joint and outcome of treatment. Patients and Methods: This study was conducted on 21 cases of fracture-dislocations of the Lisfranc joint treated in our orthopedics trauma unit from 2010 to 2013. We selected middle foot pure dislocations or associated with Lisfranc joint bone fractures. Classification of Myerson was used to characterize the lesions. The results assessment criteria were clinical and radiological for foot and Massari score. Results: Fourteen (14) patients were male. The average age was 34.7 years. Five (5) clinic pathological forms were met by relying on the classification of Myerson; 4 cases of type A; 5 cases of type B1; B2, 6 cases; 4 cases of type C1 and 2 cases of type C2. There were eight cases of pure dislocation and 13 dislocations were associated with fractures (metatarsal in 11 patients, cuneiform in 5 patients, cuboid bone in 2 patients and enucleation fracture of the medial cuneiform in 2 patients). It was noted 10 cases of skin openings. Treatment consisted on open reduction in all patients and stabilization by pin complemented by a foot plaster for 6 weeks. Four (4) immediately arthrodeses were made. All patients were followed up 7 month to 4 years (mean, 30 month). According to the criteria of Massiri, treatment outcomes were excellent in 19% of cases, good in 28%, fair in 30% and poor in 23%. Conclusion: In our context, these lesions are often open and associated with fractures of Lisfranc joint skeleton and treated after a period more or less long and sometimes, we face lesions totally old. Immediately arthrodesis can be a lasting solution and should not be overlooked.
