Can Early Treatment of Lisfranc Injuries Without Planned Re-Intervention be Safely Performed

Abstract

The Lisfranc complex is a unique combination of ligamentous and osseous relationships between the medial cuneiform and second metatarsal base that is often injured by high energy mechanisms. Fixation for these injuries is often operative; however, the optimal timing of surgical treatment has been debated. All patients who underwent operative fixation of a Lisfranc injury at a single urban tertiary care center were reviewed. Patient were split into two groups based on timing to fixation with one group being less than 24 hours from presentation and a second group being greater than 24 hours. There were 58 patients who underwent what was planned as final operative stabilization of their Lisfranc injury in less than 24 hours and 41 patients who underwent fixation after more than 24 hours. The early treatment of Lisfranc injuries did not lead to significant increases in follow up time, infections, time to weight bearing, union rates, or time to union compared patients treated with delayed fixation. There was a higher rate of superficial infection in the early intervention group, but it did not reach statistical significance. We believe our findings demonstrate that delayed fixation is not superior to early treatment of Lisfranc injuries. Level of evidenceLevel 3 Therapeutic retrospective comparative study
