aponeurosis plantaris ,
plantar aponeurosis latin

This fracture is likely caused by the lateral band of the plantar aponeurosis (tendon).

These septa ("walls") are firmly attached both to the plantar aponeurosis above and the sole's skin below.

All these muscles are covered by the thick and dense plantar aponeurosis, which, together with two tough septa, form the spaces of the three groups.

In the first layer, flexor digitorum brevis is the large central muscle located immediately below the plantar aponeurosis.

However, during a training session on the 25 July 2008, Pascal sustained an injury (a rupture of the plantar aponeurosis).

There are three distinct structural components: the medial component, the central component (plantar aponeurosis), and the lateral component (see diagram at right).

A strong band of the plantar aponeurosis connects the projecting part of the tuberosity with the lateral process of the tuberosity of the calcaneus.

The spring ligament, long plantar ligament, short plantar ligament, and plantar aponeurosis also support the plantar arch.

The flexor digitorum brevis lies in the middle of the sole of the foot, immediately above the central part of the plantar aponeurosis, with which it is firmly united.

The medial longitudinal arch in particular creates a space for soft tissues with elastic properties, which act as springs, particularly the thick plantar aponeurosis, passing from the heel to the toes.

The cutaneous branches pierce the plantar aponeurosis between the Abductor hallucis and the Flexor digitorum brevis and are distributed to the skin of the sole of the foot.

The sole and the longitudinal arch of the foot are supported by a thick connective tissue, the plantar aponeurosis, the thin borders of which blend with the dorsal fascia of the foot.

Further, it defines the plantar aponeurosis as bands of fibrous connective tissue radiating toward the bases of the toes from the medial process of the tuber calcanei (posterior half of the calcaneus).

It is continuous by its upper border with the deep fascia of the leg, and by its lower border with the plantar aponeurosis and the fibers of origin of the Abductor hallucis muscle.

It arises by a narrow tendon, from the medial process of the tuberosity of the calcaneus, from the central part of the plantar aponeurosis, and from the intermuscular septa between it and the adjacent muscles.

The other limb extends downward and medialward, to be attached to the border of the plantar aponeurosis, and passes over the tendons of the Extensor hallucis longus and Tibialis anterior and also the vessels and nerves.

The arch is further supported by the plantar aponeurosis, by the small muscles in the sole of the foot, by the tendons of the Tibialis anterior and posterior and Peronæus longus, and by the ligaments of all the articulations involved.
