 The gliding joint consists of 3 articulations: the tibiotalar, fibulotalar, and tibiofibular joints. The talus has been delineated because the solid of a cone with its apex minded medially. once viewed from the highest, the dome seems formed sort of a wedge narrowed posteriorly/medially and wider anteriorly/laterally. The leg bone plafond includes a mirror form compared to the talus, however with a extended radius of curvature. Thus, once the talus is plantarflexed, its narrowest portion sits within the mortise joint mortise and permits rotation between the talus and mortise. once the talus is maximally dorsiflexed, the tibiofibular syndesmosis accommodates the talus, and therefore the wider portion of the talar body part surface locks into the mortise joint mortise, permitting very little or no rotation between the talus and therefore the mortise. The sides of each the medial and lateral malleoli ar parallel to corresponding sides of the talus. there's body part contact at these sides from extreme plantarflex-ion through complete flexion. Different radii of curvature are found between the talus and therefore the mortise moreover as between the talus and therefore the mortise sides. The gliding joint was erst thought to operate as an easy hinge whose primary axis was transversal and perpendicular to the mesial plane. it's been shown, however, that the first axis is related to with the transmalleolar plane and outwardly revolved a median of twenty three degrees. Recent studies have incontestible that the axis of rotation isn't fastened however rather changes direction and position throughout mortise joint motion. The position and orientation of those axes account for coupled mortise joint motion. because the mortise joint is dorsiflexed, it rotates outwardly and everts. Conversely, because the mortise joint is region flexed, it rotates internally and inverts.
