23
Q

Plantar Fascia

A

The plantar fascia is a flat, thick band of connective tissue that connects the calcaneal tuberosity of the calcaneus bone to the ligaments around the heads of the metatarsal bones.
It supports the arch on the bottom of the foot and is very strong.
If stretched or overworked, it becomes inflamed and the pathology is called plantar fasciitis.

24
Q

Retinacula of the Ankle

A

A retinaculum is a band of thickened deep fascia. It occurs in a region of the body where tendon groups pass through, usually around joints. The function of a retinaculum is to stabilize and hold the tendons in place.
Superior and Inferior Extensor Retinaculum
holds down the extensor tendons
Superior and Inferior Fibular Retinaculum
holds down the fibular or peroneal tendons
Flexor Retinaculum
holds down the flexor tendons (not shown)

25
Q

Bursa of the Ankle

A

Bursa: a fluid filled sac that cushions and lubricates against the friction between tendons and bones when the are moving against each other.
In the ankle we have one main region that gets high friction and requires a bursa, it is between the calcaneus and the achilles tendon.
We have two bursa between the achilles tendon and the calcaneus:
Superficial or Subcutaneous Calcaneal bursa
Deep or Retrocalcaneal bursa

26
Q

Foot Musculature

Extension
Big Toe: extensor hallucis longus & brevis
Toe 2-5: extensor digitorum longus & brevis
Abduction: dorsal interossei
Adduction: plantar interossei

27
Q
