Calcaneal Branches Lateral

The calcaneal branches (ramus calcaneus) are an integral part of the calcaneal branches (rami plantares), which form the lateral wall of the posterior part of the popliteal fossa.

The calcaneal branches begin from the lateral wall of the canal through which the posterior tibial artery passes. They run along the medial edge of the Achilles tendon and are directed towards the lateral side of the heel. Near the lateral surface of the heel, these branches run parallel to each other and the superficial peroneal artery. The distance between the calcaneal branches is approximately 5 cm, and their total length is 9-11 cm. Approximately one and a half finger diameters above the lateral edge of the notch at the junction with the sole, these branches connect with the lateral branch of the epiglottis and the plantar aponeurosis. Above the joint, about one and a half toes across, they grow into the deep fascia of the foot. Thus, the calcaneal nerve, which passes along with the Friday branches, is enclosed in a triangle between the plantar fascia, the inner layer of skin (covering both the extensor portion of the dorsum of the foot and the back of the toes.) and the sole. By inserting into the fascia of the foot, this triangular piece of tissue is strengthened and protects the nerve elements. The calcaneal and calcaneal nerves innervate the skin on the plantar surface of the heel and on the back of the foot, including the spaces between the toes.
