What is the rear arch?

The foot area known as the rear arch includes an area on the underside of the foot that leads from the top of the arch to the heel. This part of the foot contains Tarsus, a collection of small irregular bones that connect the heel and ankle with the front of the foot. A number of muscles, tendons and their surrounding fascia contribute to the rear arch and maintain its shape. The arch is important for its role in carrying weight towards the front of the foot when the leg hits the ground.

In fact, composed of two longitudinal arches, medium and side anteroposterior arches, the arch of the foot runs from the front to the back. Its front consists of five metatarsal bones, one leading to each tip in the front half of the leg. The first to third metatars, those who are in line with the large and the second two fingers, form the middle front arch, while the fourth and fifth metatars, those who are in harmony with the two top leaders, fold the side front arch.

Metatars encounter tarsal bones at the highest point of these arches, where the rear arch begins. Tarsus consists of Calcaneus, Talus, Navicular, Cvat and Three V -bones, while Kalcaneus also known as heel and talus located on the top of the heel under the ankle. Five bones are connected to the middle leg: Navikular on the middle or large side of the foot, blocking on the side or small top side of the foot and the first to the third bone on the middle side in front of it. Part of the media arc are talus, calcaneus, navicular and three key bones, while in the side rear arch are the outer part of Calcaneus and Cubuid.

The passing rear arch below and between these bones is multi -fT tissue that lends the arch support and elasticity. The most important of these are plantar cylindrical ligaments, plantar aponeurosis and tendon of the rear muscles of tibialis. Plantar Calcaneonavicular liga is a thick strip of fibrous tissue that intersects the rear arch and connectsCalcaneus bone with navicular bone. It is also known as the spring ligament for elasticity, which lends the arch.

Similarly, plantar aponeurosis or plantar facade soft tissue of the rear arch that passes from the bone of the heel to metatars and helps to support the arc and transmission of force towards the ball of the foot. Plantary fasciitis is a common and well known condition in which this tissue is painfully inflamed. The rear arch is also supported and stabilized by branches of the tendon of the back of the tibialis, the deep muscle of the calf. This tendon is divided into several segments in the back part of the Calcaneus, Navicular, Cvoid and all three kitchens in the rear arch, as well as the middle three metatarsl in the front arch.
