Document Summary

Medial mortise joint = medial malleolus of tibia + talus. Lateral mortise joint = lateral malleolsu of fibula + talus. The malleoli form a cap over the upper surface of the talus limiting the ankle joint to flexion and extension. Medial malleoli is higher than lateral, and more anterior. Medial collateral ligament from the tibia to the talus, the calcaneous and the navicular. Axial relaltionships : a line drawn through the mid portions of the 2 malleoli will be approx. 15-20 degrees from the coronal plane from lateral aspect the distal fibula is approx. 15-20 degrees posterior to the medial mall: tibial shaft is perpendicular to the horizontal plane of the ankle joint. And continous with vertical axis of the talus talus lies perpendicular always to how the tibia is lying efficient for weight transfer. Formed by medial and lateral aspect of the trochlear surfaces of the talus.
