Joints of left ankle and foot
Ligaments of plantar aspect of foot, deep layer
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.
1 . Peroneus longus muscle (insertion on 1st metatarsal)
2 . Plantar tarsometatarsal ligament
3 . Tibialis posterior muscle (part of insertion)
4 . Medial cuneiform bone
5 . Plantar cuneonavicular ligament
6 . Plantar cuboideonavicular ligament
7 . Tibialis posterior muscle (principal insertion on navicular bone)
8 . Plantar calcaneonavicular ligament (spring ligament)
9 . Sustentaculum tali
10 . Medial malleolus
11 . Medial process of tuberosity of calcaneus
12 . Plantar metatarsal ligaments
13 . Groove for peroneus longus tendon
14 . Tuberosity of cuboid bone
15 . Calcaneocuboid plantar ligament
16 . Long plantar ligament
17 . Inferior peroneal retinaculum
