Mid-term Radiologic and Clinical Results of Pediatric-adolescent Lisfranc Injuries

Abstract

Introduction: The incidence of Lisfranc injury in pediatric-adolescent children is lower compared with adults. There is limited research on adolescent patients in this age group, with only a few case reports of pediatric patients. Furthermore, studies with adequate follow-up are lacking in the literature. This study aims to provide insights into the causes and types of fractures and evaluate mid-term clinical and radiologic outcomes. Methods: A retrospective analysis was conducted on pediatric-adolescent patients diagnosed with a Lisfranc injury who underwent surgical treatment between June 2015 and January 2022. Patients underwent open reduction and internal fixation using Kirschner wires and/or screws, had satisfactory imaging, and were followed up for at least 2 years. Radiologic measurements included intermetatarsal distance, meary angle, and calcaneal height angle, done while the patient was standing. Assessments were made using the AOFAS midfoot score, the Oxford Ankle Foot Questionnaire for Children (OxAFQ-C), Visual Analog Scale (VAS) scores, and physical activities. Results: The study included 14 surgically treated patients with a minimum 2-year follow-up. The average patient age was 12.6 years, with a mean follow-up of 52.4 months. In pediatric cases, crush injury was the predominant trauma type (P = 0.009). There were no significant differences in calcaneal pitch angle or meary angle between healthy and injured feet (P = 0.2 and 0.1), but a greater intermetatarsal distance was observed on the injured side (P = 0.02). The mean Visual Analog Scale (VAS) score was 1.5, the AOFAS midfoot score averaged 91.5, and the OxAFQ-C score averaged 86.3%. Conclusions: The mid-term outcomes for this age group were promising compared with adults. The use of Kirschner wires for fixation is more common in younger patients. Crush injuries and complications like compartment syndrome are more prevalent in the pediatric age group. © 2025 Wolters Kluwer Health, Inc. All rights reserved.
