Medial Longitudinal Arch

Extends from calcaneus bone to talus, navicular, 3 cuneiform and proximal ends of 3 medial metatarsals. Used for deceleration. All arches used for shock absorption and weight bearing.

Lateral Longitudinal Arch

Extends from calcaneus to cuboid and proximal ends of 4th and 5th metatarsals. Provides balance. All arches used for shock absorption and weight bearing.

Transverse arch

Extends across foot from 1st metatarsal to the 5th metatarsal. Adapts to changes in terrain. All arches used for shock absorption and weight bearing.

Universal function of all foot arches

All arches used for shock absorption and weight bearing.

Specific functional purpose of the Medial Longitudinal Arch

Used for deceleration.

Specific functional purpose of the Lateral Longitudinal Arch

Provides balance.

Specific functional purpose of the Transverse arch

Adapts to changes in terrain.

Lateral Ankle Ligaments (outer ankle)

Anterior Talofibular Ligament, Posterior Talofibular Ligament, Calcaneofibular Ligament.

Medial Ankle Ligament (inner ankle)

Deltoid Ligament.

Syndesmotic Ankle Ligaments (high ankle)

Anterior-Inferior Tibiofibular Ligament, Posterior-Inferior Tibiofibular Ligament, Transverse Tibiofibular Ligament, Interosseous Ligament.

High Ankle Sprain

External rotation injury involving syndesmotic ligaments.

Low Ankle Sprain

Inversion injury involving lateral ligaments.

Fore foot: mobile or stable?

Stable.

Ankle: stable or mobile?

Mobile.

Lumbaricals

Flexes the toes at the metatarsophalangeal joint. Extends toes at the interphalangeal joint. This action prevents the toes from hyperextension during push-off phase of Gait and stops the toes from crawling under the pull of the long flexor tendons.

Role of the Lumbaricals during the push-off phase of Gait

Prevents the toes from hyperextension during push-off phase of Gait and stops the toes from crawling under the pull of the long flexor tendons.

Abductor Hallicus

Abducts and flexes the great toe at the metatarsophalangeal joint, while heavily supporting and elevating the medial longitudinal arch of the foot.

Action of Abductor Hallicus on the arch of the foot

Heavily supporting and elevating the medial longitudinal arch of the foot.

Plantar Fascia

A band of connective tissue that runs from your forefoot to your level.

Flexor hallucis longus

It starts on the lower two-thirds of the back of the fibula and the adjacent interosseous membrane. It attaches to the base of the distal phalanx of the big toe. It bends the big toe, helps with push-off, and assists ankle plantarflexion.

Origin and insertion of Flexor hallucis longus

Starts on the lower two-thirds of the back of the fibula and the adjacent interosseous membrane, and attaches to the base of the distal phalanx of the big toe.

Actions of Flexor hallucis longus

Bends the big toe, helps with push-off, and assists ankle plantarflexion.

Ankle dorsiflexion

$35^{\circ}$ of forward shin tilt from vertical, measured with the heel flat as the knee moves toward the wall.

Bones forming the Medial Longitudinal Arch

Calcaneus bone, talus, navicular, 3 cuneiform, and proximal ends of 3 medial metatarsals.

Bones forming the Lateral Longitudinal Arch

Calcaneus, cuboid, and proximal ends of 4th and 5th metatarsals.
