Inferior Peroneal Retinaculum Anatomy, Perform & Diagram

A retinaculum refers to any area on the physique the place tendon teams from completely different muscular tissues go underneath one connective tissue band. The inferior peroneal retinaculum is situated within the ankle and foot areas. It’s considered one of two components of the peroneal retinaculum. The tendons of the inferior retinaculum cowl the facet of the ankle and run into the foot. (Tendons are connective tissue that often join muscle to bone.)

These tendons lengthen over the fibula, or calf bone, and the peroneus longus tendons connected to the peroneal muscular tissues within the calf. They run right into a ligament within the ankle joint generally known as the cruciate crural and proceed from the place the inferior extensor retinaculum ends.

The tendon’s level of attachment is the floor of the heel bone, or calcaneus. The inferior retinaculum is accountable for stabilizing the tendons that reach from the calf muscular tissues as they run down the leg to achieve either side of the ankle.

Medical situations that originate from an damage of the inferior peroneal retinaculum generally have an effect on athletes. The tendon can tear from forceful motions and the damage usually requires at the very least six to eight weeks for the tendon to heal absolutely.
