Treatment of paediatric Lisfranc injuries: A systematic review and introduction of a novel treatment algorithm

BACKGROUND: Pediatric Lisfranc injuries (PLI) are rare injuries that have few studies published about their occurrence and treatment in pediatric population. Due to this lack of information, the diagnostic criteria and surgical or non-surgical methods for treatment have not been clearly established within the pediatric orthopedic literature. The objective of this study was to review the published literature related to treatment options and develop a concise stepwise treatment algorithm for pediatric patients presenting with Lisfranc injuries. METHODS: A systematic literature review was conducted using PubMed to find studies discussing the treatment of PLI with reported long-term outcomes. Data collection accounted for the mechanism of injury, diagnostic imaging modality used, injury type, fracture classification using the Myerson system, treatment method used, and postoperative complications. RESULTS: An initial PubMed search revealed 290 articles, but only 10 studies fulfilled the criteria for in-depth review. A total of 114 patients were included in this review from the selected case reports and case series studies. Primary treatment methods were as follows: 44% (50/114) with open reduction internal fixation (ORIF) using Kirschner wires (K-wires) and/or screws, 3% (3/114) with closed reduction percutaneous fixation (CRPF), 4% (4/114) with suture-button constructs, 20% (23/114) with cast immobilization, and 29% (33/114) were described as not requiring reduction. CONCLUSION: There were two main limitations to this study. First, there are few published studies with longitudinal outcomes of PLI treatment. Second, some case series did not disclose which procedure a patient with post-treatment complications underwent. Therefore, an overall statistical analysis of success and failure rates with associated complications of each procedure could not be conducted. In conclusion, we found that a stepwise approach to evaluating conservative and surgical treatment options based on the presentation of the PLI should be utilized to optimize long-term outcomes.
