Abstract
BackgroundThis study aimed to evaluate the shape of the retromalleolar groove of the tibialis posterior tendon (TPT) using computed tomography (CT). MethodsCT images of patients with foot or ankle pathologies were retrospectively reviewed. The morphology of the retromalleolar groove of the TPT was assessed at two different levels: the ankle joint and 10 mm above the ankle joint. The groove shape was classified into three types; concave, flat, or irregular. In cases with concave grooves, the width and depth of the grooves were measured. ResultsOf the 116 ankles from 116 subjects included in this study, 80.2 % showed a shallow concave shape (mean depth, 1.6 mm) at the two scan levels. The shape and width of the groove differed significantly by gender, although there was no significant difference in the groove depth. ConclusionApproximately 80% showed a shallow concave groove of the TPT. The groove characteristics differed by gender, although there was no significant difference in the groove depth.
