What is peroneal retinaculum?
What is peroneal retinaculum?
The peroneal retinaculum also termed the fibular retinaculum, consists of band shaped thickenings of deep fascia located posterior and inferiorly to the distal aspect of the fibula.
What is the function of the peroneal retinaculum?
Anatomical terminology The peroneal retinacula (singular: peroneal retinaculum) are fibrous retaining bands which bind down the tendons of the peroneus longus and brevis as they run across the side of the ankle. (Retinaculum is Latin for retainer).
What is flexor Retinaculum foot?
The flexor retinaculum is a dense band of fibrous tissue that forms a sort of tunnel, or tube. Several tendons, as well as the nerve, artery, and veins that travel to the bottom of the foot pass through this tunnel. This tunnel is called the tarsal tunnel.
What is peroneus?
The peroneus longus muscle is a major mover and stabilizer of your ankle. The muscle, along with the peroneus brevis and tertius, courses down the lateral side of your lower leg and attaches to your foot. It serves to move your foot and ankle in various directions.
What is the peroneal sheath?
The peroneal tendons are a paired tendons structure that lies in a common sheath on the lateral aspect of the hind foot. As they pass posterior to the lateral malleolus their position is maintained by the presence of a connective tissue band termed the superior peroneal retinaculum.
Is the superior peroneal Retinaculum a ligament?
The fibers of the superior retinaculum (external annular ligament) are attached above to the lateral malleolus and below to the lateral surface of the calcaneus.
What is retinaculum in knee?
The medial patellar retinaculum is a tendon of the knee that crosses the knee joint on the medial side of the patella. It plays important roles in the formation of the fibrous capsule of the knee and in the extension of the knee joint.
What is a retinaculum anatomy?
Retinacula are thickenings of tissue underneath your skin that serve to bind down tendons of muscles so they don’t “bowstring” at certain joints, meaning pop up when the joint is flexed or extended.
What is superior extensor Retinaculum?
The superior extensor retinaculum is a transverse, roughly rectangular band located above the tibiotalar joint. It attaches laterally on the lateral crest of the lower fibula and the lateral surface of the lateral malleolus and me- dially on the anterior crest of the tibia and the medial malleolus (Figs.
What is the peroneal complex?
The peroneus muscles (also called fibularis muscles or peroneals or peronæus) are a group of muscles in the leg. While the muscle group exists in many variations, it is normally composed of three muscles: peroneus longus, brevis and tertius.
What is the function of the superior peroneal retinaculum?
Superior peroneal retinaculum. The superior peroneal retinaculum is one of two fibrous bands that bind the peroneus longus and peroneus brevis muscle tendons that run over the ankle’s lateral side. While these muscles stabilize the lateral ankle and evert (bend outward) the foot, the superior peroneal retinaculum creates a fibro-osseous
What is the fibular retinaculum attached to?
Description The fibular retinacula (peroneal retinacula) are fibrous bands which bind down the tendons of the Peronæi longus and brevis as they run across the lateral side of the ankle. The fibers of the superior retinaculum (external annular ligament) are attached above to the lateral malleolus and below to the lateral surface of the calcaneus.
What is Oden’s classification for peroneal injuries?
One method of grading is the Oden’s classification 1,7 which classifying injuries into four types: type I elevation or stripping off of the periosteal attachment of the superior peroneal retinaculum to the lateral malleolus at the level of the fibular groove type II: tear of the superior peroneal retinaculum at its attachment to the distal fibula
What are the treatment options for peroneal retinopathy?
Fortunately, such conditions can be corrected by reconstructive surgery, which directly repairs the ankle’s superior peroneal retinaculum; however, this is difficult in patients with insufficient structural remnants.
