What is the function of the inferior extensor retinaculum?

Inferior extensor retinaculum: The Y shape has the function of preventing “Bowstringing” of the tendons during ankle motion.

What does the inferior extensor retinaculum stabilize?

The structure indicated is the inferior extensor retinaculum. Retinacula (retinaculum singular) are bands of connective tissue which surround tendons and hold them in place. They function to stabilise tendons as the muscles to which they attach contract to cause movement.

What is the function of the retinaculum?

A retinaculum (plural retinacula) is a band of thickened deep fascia around tendons that holds them in place. It is not part of any muscle. Its function is mostly to stabilize a tendon. The term retinaculum is New Latin, derived from the Latin verb retinere (to retain).

What passes behind the extensor retinaculum?

Four tendons, a nerve and an artery pass under the extensor retinaculum. On the lateral aspect, behind the malleolus, here’s the peroneal retinaculum.

Can retinaculum repair itself?

Background: Superior peroneal retinaculum tears are often mistaken for lateral ankle instability. These tears often do not heal readily by themselves and must be identified so that proper treatment can begin.

Can you tear your extensor Retinaculum?

A rupture of the extensor retinaculum could result in a loss of dorsiflexion power, prominent tendons in the anterior aspect of the ankle and local inflammation due to lack of appropriate tracking or sliding disturbance of the tendons.

Is the inferior extensor retinaculum a muscle?

The inferior extensor retinaculum of the foot (cruciate crural ligament, lower part of anterior annular ligament) is a Y-shaped band placed in front of the ankle-joint, the stem of the Y being attached laterally to the upper surface of the calcaneus, in front of the depression for the interosseous talocalcaneal …

Which is an example of a retinaculum?

For example, there is a retinaculum on the underside of your wrist that keeps tendons from popping up when you flex or bend your hand at the wrist. One of the muscle tendons at the wrist, the palmaris longus, “the long muscle of the palm”, is outside of the retinaculum, that is, not bound down.

Does fascia connect muscle to bone?

Fast facts about fascia: Fascia connects all connective tissues (that means the muscles, bones, tendons, ligaments, and blood) Fascia holds together the entire body.

Where is extensor retinaculum found?

wrist
The extensor retinaculum of the wrist is the broad ligamentous sheet located at the dorsal aspect of the wrist and functions to keep the extensor tendons in alignment and prevent bowstringing during movement.

How long does it take for the retinaculum to heal?

Recovery from surgery requires a moderately long period, usually in the order of 2-6 weeks of immobilization, in order to allow the retinaculum and any bony procedures to heal. This is followed by four to six weeks of fairly graduated and intensive rehabilitation.

Where is the inferior extensor retinaculum located in the foot?

The inferior extensor retinaculum of the foot ( cruciate crural ligament, lower part of anterior annular ligament) is a Y-shaped band placed in front of the ankle-joint, the stem of the Y being attached laterally to the upper surface of the calcaneus, in front of the depression for…

What is the relationship between tibialis and extensor retinaculum?

Under the hypothesis that the anatomic relationship of the tibialis anterior tendon and extensor retinaculum of the foot and ankle is relevant to the clinical aspects of a tear in that t… OBJECTIVE.

Why is the inferior extensor retina considered a double layer?

The inferior extensor retinaculum is considered a double layer due to one lamina (thin sheet) passing behind and the other passing in front of the tendons of the extensor digitorum longus and the peroneus tertius.

What causes pain in the inferior extensor retina?

To sum it up, some of the common causes Inferior Extensor Retinaculum pain or strain are simple sprains, fractures, twisting injury, or injuries which result in tear to ligament or tendons. What is the Treatment for Inferior Extensor Retinaculum Pain?
