Imaging of Proximal Tibiofibular Joint Instability: A 10 year retrospective case series

ObjectiveDetail the imaging findings in patients with proximal tibiofibular instability treated with surgical stabilization.MethodsRetrospective analysis of preoperative imaging in patients with clinically confirmed tibiofibular instability.ResultsOperative fixation of the 16 patients was as follows: 11 using a fiberwire suture construct and 5 using screw fixation. Proximal tibiofibular ligamentous abnormalities were present in 100% of acute (< 6 months) and 85.7% of chronic (> 6 months) instability cases who underwent MRI.ConclusionMRI is sensitive in the evaluation of tibiofibular ligamentous integrity in proximal tibiofibular instability. Chronic instability should be considered in younger adults with isolated tibiofibular osteoarthritis.
