Comparison Between Standard Screw and Internal Brace in Treatment of Subtle Lisfranc Injury

Key Points

At 6 months, internal brace fixation improved clinical outcomes, with higher AOFAS and lower VAS scores than standard screw fixation.
Both the internal brace and screw fixation groups showed improvement from preoperative status, with no significant side-to-side differences in pedobarography.
The internal brace demonstrated comparable final stability metrics to screw fixation, despite differing initial outcomes.
Importantly, internal brace fixation resulted in fewer hardware-related complications, such as no instances of implant breakage or severe recurrent diastasis.

Abstract

Background: Subtle Lisfranc injuries are low-energy, purely ligamentous lesions increasingly recognized in active patients; although screw fixation is common, Internal Brace (IB) flexible fixation is an alternative. Methods: In this multicenter retrospective study (2014-2021), 65 patients with subtle ligamentous Lisfranc injury (C1-M2 diastasis Results: Demographics and injury mechanisms were similar. Both groups improved from preoperative status to final follow-up (p p Conclusions: In this Level III study, IB fixation was associated with better 6-month clinical outcomes with similar final radiographic stability and fewer hardware-related complications versus SS.
