The capsules of the ankle and subtalar (talocalcaneal)joints remain intact. In addition, a layer of fascia (5) has been retained posteriorly. This layer continued laterally into the superior peroneal retinaculum and blended medially into the flexor retinaculum.
1 . Fibula
2 . Posterior tibiofibular ligament
3 . Lateral malleolus
4 . Superior peroneal retinaculum (divided)
5 . Fascia posterior to ankle joint (this layer blended with superior peroneal retinaculum)
6 . Calcaneofibular ligament
7 . Subtalar articular capsule
8 . Inferior peroneal retinaculum
9 . Calcaneus
10 . Lateral tubercle process of calcaneus bone
11 . Medial malleolus
12 . Upper pointer: Groove for tendon of tibialis posterior muscle Lower pointer: Groove for tendon of flexor digitorum longus muscle
13 . Talocrural articular capsule
14 . Deltoid ligament
15 . Groove for tendon of flexor hallucis longus muscle
16 . Tibialis posterior muscle (cut off at insertion into tuberosity of navicular)
17 . Sustentaculum tali
