ABSTRACT
PURPOSE: While treatment modalities for Maisonneuve fractures involving the proximal third of the fibula are established, no studies to date have reported outcomes associated with syndesmotic-only fixation of middle third fibular shaft fractures. The purpose of this study was to evaluate outcomes associated with syndesmotic-only fixation in the treatment of Maisonneuve fractures involving the middle third of the fibula.
METHODS: A retrospective review was conducted on 257 cases of syndesmotic ankle instability with associated fibular fractures at a level 1 trauma center between 2013 and 2023. Patients were divided into cohorts based on fibular fracture location in the proximal, middle, or distal third of the fibula. The Chi-square test of independence, two-sample t-test, and analysis of variance were used to compare outcome measures between cohorts.
RESULTS: Sixty-six patients were identified including 48% (n = 32) with proximal third fibular fractures, 20% (n = 13) with middle third fibular fractures, and 32% (n = 21) with distal third fibular fractures. Rates of infection, loss of reduction, wound healing complications, and reoperation did not vary significantly between cohorts. Functional outcome measures including range of motion, time to weight-bearing, and tibiofibular/medial clear space measurements at final follow-up were similar across cohorts.
CONCLUSION: Patients with Maisonneuve fractures involving the middle third of the fibula demonstrated positive outcomes with syndesmotic fixation alone, with no documented cases of infection, loss of reduction, or wound healing issues. By demonstrating maintenance of anatomic reduction and low rates of complications, our results support the use of syndesmotic-only fixation in the treatment of middle third Maisonneuve fractures.
