Open Reduction Internal Fixation vs Primary Arthrodesis for Displaced Lisfranc Injuries: A Multicenter Randomized Controlled Trial.
OrthoEvidence Journal (OE Journal) - ACE Report

Both ORIF and PA are viable initial surgical options for displaced Lisfranc injuries, demonstrating comparable functional outcomes at 24 months. However, clinicians should be mindful of the higher complication rates associated with ORIF, particularly the increased likelihood of screw removal. Despite these findings, the study's underpowered design due to recruitment challenges limits the robustness of its conclusions. In clinical practice, both techniques are reasonable, but the choice of treatment should be individualized based on patient characteristics and preferences. The study's small sample size and underpowered nature highlight the need for further research to detect potential smaller differences between these treatment options.
Study Summary
Forty-three patients with displaced Lisfranc injuries were randomized to receive open reduction and internal fixation (ORIF, n=22) or primary arthrodesis (PA, n=21). The primary outcome was the Visual Analogue Scale Foot and Ankle (VAS-FA) score at 24 months. Secondary outcomes included subscales of the VAS-FA (pain, function, and complaints) and the American Orthopaedic Foot & Ankle Society (AOFAS) Midfoot Scale, assessed at 6, 12, and 24 months. Overall, the results revealed no significant differences in VAS-FA or AOFAS scores between the two groups across all follow-up points. Both ORIF and PA appear to be viable initial surgical methods for displaced Lisfranc injuries. However, the study was underpowered to detect smaller differences, suggesting further research is needed.
