Deltoid ligament/Medial Collateral Ligament components
- Tibiocalcaneal
- Tibionavicular
- Posterior Tibiotalar
- Anterior tibiotalar
Lateral Collateral Ligament components
- Anterior talofibular
- Posterior talofibular
- Calcaneofibular
Anterior retinaculum
Superior and inferior extensor retinaculum
Posteriormedial retinaculum
Flexor retinaculum
Lateral retinaculum
Superior and inferior peroneal retinaculum
Structures passing beneath superior and inferior extensor retinaculum (6)
(Tom And Dick Even E-vited Paul)
- tibialis anterior tendon
- anterior tibial artery
- deep peroneal nerve
- extensor hallucis longus tendon
- extensor digitorum longus tendon
- Peroneus tertius muscle
Structures passing beneath flexor retinaculum (superficial to deep) (5)
(Tom Fought Paul, Tom Fell)
- Tibialis posterior tendon
- flexor Digitorum longus tendon
- posterior tibial vessels
- tibial Nerve
- flexor Hallucis longus
Structures passing beneath superior and inferior peroneal retinaculum
peroneus longus and brevis
Tarsal bones
- 3 cuneiform bones
- talus
- calcaneus
- cuboid
- navicular
3 foot arches
- medial longitudinal
- lateral longitudinal
- transverse
Medial longitudinal arch
- Supported by plantar ligaments, intrinsic muscles of the sole of foot, and plantar aponeurosis
- tibialis posterior and anterior suspend arch from above
Lateral longitudinal arch
- Supported by plantar ligaments, plantar aponeurosis, lateral intrinsic muscles of foot.
- Peroneus longus and brevis suspend arch from above
Transverse arch
- Supported by plantar ligaments, deep transverse metatarsal ligaments, and intrinsic foot muscles
- Peroneus longus suspends arch
Cutaneous innervation of dorsum of foot
Superficial peroneal nerve (medial and intermediate dorsal cutaneous nerves –> dorsal digital branches)
Cutaneous innervation of lateral of foot
lateral dorsal cutaneous nerves
