The tibial malleolar sulcus, also known as the malleolar groove, is the smooth, vertical depression found on the posterior aspect of the medial malleolus. [1] [2] [3] This groove is traversed by the tendons of the tibialis posterior and flexor digitorum longus muscles. [1] [4]
There are two malleolar sulci, medial and lateral. [2] The medial malleolar sulcus is the posto-inferior groove just lateral to the medial malleolus on the distal part of the tibia. [5] It is where the tendons of the tibialis posterior and flexor digitorum longus course on their way to their insertions on the foot. The lateral malleolar sulcus is the posto-inferior groove on the distal part of the fibula. [5] The tendons of the peroneus longus and peroneus brevis course behind it on the way to their insertions on the foot. [5]
