Joints of left ankle and foot
Ligaments of ankle and foot, medial view
The tendons of the peroneus longus and tibialis posterior muscles have been cut off at their insertions (1, 3, 7) to permit the deeper-lying ligaments to be brought to view. The groove marking the course of the peroneus longus tendon across the plantar part of the foot can be readily traced in the specimen (13). Facets on the calcaneus and cuboid bone are visible along the path occupied by this tendon.
