Abstract

Objective. Computed tomography (CT) is superior to plain radiography for evaluating ankle syndesmosis, but anatomic variations can affect the measurements. This study aimed to assess the radiological parameters of incisura fibularis and the factors that could affect these parameters.

Materials and Methods. Lower extremity CT angiography images were used to evaluate the morphology of the incisura fibularis, anterior/posterior tibiofibular distance, longitudinal/transverse length of the distal fibula, length/depth of the incisura fibularis notch, tibiofibular clear space, tibiofibular overlap, and fibular rotation. Each measured parameter was compared based on gender and body sides. Also, the effect of age, height, weight, and body mass index (BMI) on parameters was evaluated.

Results. A total of 123 patients (83 males, 40 females) were included, and 246 ankles were measured. CT measurements demonstrated excellent intra-observer and interobserver reliability. No significant gender or side differences were found in tibiofibular overlap (TFO) and tibiofibular clear space (TFCS), the most used parameters in x-rays. Age, weight, and BMI were found to be correlated with TFO.

Conclusions. The present study has provided CT measurements of the normal tibiofibular syndesmosis in the Turkish population. Also, the correlations of the parameters with age, height, weight, and BMI were presented. Therefore, TFO and TFCS of the uninjured side can be used to plan the treatment of ankle injuries.
