Tarsometatarsal Lisfranc Injuries: A Diagnostic Challenge

Abstract

Introduction: Lisfranc injuries are often difficult to diagnose and treat causing long term disability without proper management. Lisfranc injuries refer to bony or ligamentous compromise of the tarsometatarsal and intercuneiform joint complex. Improper treatment of these fractures might lead to negative outcomes such as soft tissue necrosis, posttraumatic arthritis and arch abnormalities. This study aims to help in diagnosis and treatment of tarsometatarsal Lisfranc injuries. Materials and Methods: Study comprises of 10 patients diagnosed with Lisfranc injury. All of them were treated with open reduction and internal fixation. Post-operatively, all patients were assessed using AOFAS midfoot scale for outcome after the surgery and scores were recorded at each follow up and final results were evaluated after 1 year of surgery. Observation and Results: Mean AOFAS midfoot score was 82 at the end of one year. Majority of the patients had AOFAS score of more than 80. Majority of patients had B2 type of fracture according to Meyerson Classification. Conclusion: Anatomical reduction is the key for the treatment of lisfranc injuries, therefore, open reduction and internal fixation is necessary to provide good outcome.
