Document Summary

Ankle joint: the (talocrural articulation) is hinge-type synovial joint that is located between the distal ends of the tibia and fibula and the superior part of the talus. Articular surface: the distal ends of the tibia and fibula (along with the inferior transverse part of the posterior tibiofibular ligament) form a malleolar mortise (deep socket) into which the pulley shaped trochlea of the talus fits. The trochlea (l. pulley) is the rounded superior articular surface of the talus. The medial surface of the lateral malleolus articulates with the lateral surface of the talus. The tibia articulates with the talus in two places: Its inferior surface forms the roof of the malleolar mortise transferring the bodies weight to the talus. Its medial malleolus articulates with the medial surface of the talus. Joint capsule: the joint capsule is thin anteriorly and posteriorly but is supported on each side by strong collateral ligaments.
