What passes through flexor retinaculum of foot?
The flexor retinaculum of the foot extends from the medial malleolus above, to the calcaneus below. This converts a series of bony grooves into canals for the passage of the tendons of the flexor muscles and the posterior tibial vessels and tibial nerve into the sole of the foot, known as the tarsal tunnel.
What is the retinaculum of the foot?
A retinaculum is a band of thick deep fascia that holds the long tendons of your ankle (those that cross the ankle) in place. Retinaculum also acts as a pulley system increasing mechanical advantage.
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.
What muscles pass under the extensor retinaculum?
The superior extensor retinaculum binds down the tendons of extensor digitorum longus, extensor hallucis longus, peroneus tertius, and tibialis anterior as they descend on the front of the tibia and fibula; under it are found also the anterior tibial vessels and deep peroneal nerve.
What passes through peroneal Retinaculum?
The peroneal retinaculum is divided into the superior and inferior peroneal retinaculum 1. They house the tendons of fibularis longus and brevis as they pass through the lateral aspect of the ankle joint posterior to the lateral malleolus 1.
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.
Is the extensor retinaculum a tendon?
The extensor retinaculum (dorsal carpal ligament, or posterior annular ligament) is an anatomical term for the thickened part of the antebrachial fascia that holds the tendons of the extensor muscles in place. It is located on the back of the forearm, just proximal to the hand.
Why does my flexor Retinaculum hurt?
Tarsal tunnel syndrome (TTS) is a compressive neuropathy of the posterior tibial nerve. The tunnel lies posterior to the medial malleolus of the ankle, beneath the flexor retinaculum. Symptoms include pain radiating into the foot, usually, this pain is worsened by walking (or weight-bearing activities).
