What is Flexor Retinaculum?
Flexor Retinaculum is a ligament or a piece of hard fibrous tissue in the body. There are four flexor retinacula in the human body, one in each wrist and one in each ankle. They are also known on the wrist as transverse carpel ligaments and are also known in the ankle as tuning ligaments or internal annular ligaments. The function of the ligaments is to connect and support bones and structures and maintain proper anatomical positioning.
In the wrist, the flexor retinaculum stretches through the carpal bones and creates a carpal tunnel. The middle nerve passes through the carpal tunnel from the forearm to the hand. Flexor tendons also pass through the carpal tunnel. If the flexor retinaculum suffers injuries, it can swell, stretch too tightly or tear, allowing carpel bones to move incorrectly. These actions can compress the middle nerve that passes through the tunnel, causing pain, numbness and lack of mobility in hand.
Carpal Tunnel Syndrome is a state of general caused by swelling of the membrane that protects tendons while browsingtunnel. As the membrane swells, the middle nerve is compressed between the carpal bones and the flexor retinaculum. One of the surgical options for the treatment of the carpal tunnel tunnel syndrome includes an incision in flexor retinaculum to alleviate the middle nerve compression.
Flexor Retinaculum has a similar function in the ankle as in the wrist. It stretches over a series of bones in the ankle and creates a narrow passage or tunnel known as a tarsal tunnel. The function of the flexor retinacula in the ankle is to maintain, protect and support the tunnel of the tarsal tunnel and the structures that pass. The tibial nerve passes through the tarsal tunnel, along with veins, arteries and tendons, on the way to the foot.
If the tibial nerve is compressed inside the Tarsal tunnel, there may be a state called Tarsal tunnel syndrome. Tarsal tunnel syndrome is similar to carpal tunnel syndrome in that both conditions include symptoms resulting from the nerve that stressed themChen in a limited space, but the tarsal tunnel syndrome is less common than the carpal tunnel syndrome. Flexor Retinaculum is unable to stretch very far, so anything that occupies another space in the Tarsal tunnel can contribute to the tarsal tunnel syndrome. Beautiful veins, inflammation of the surrounding tissues, tumors or cysts in the tunnel can bring symptoms including pain, numbness and muscle weakness.
People who have fallen arches are flat legs or walking on the outer edge of the foot are exposed to a greater risk of developing a tarsal tunnel syndrome. This is because these conditions lay greater stress of retinacula flexor, as well as many structures that protect, and this can lead to irritation and inflammation that can cause B tabial nerve Become compressed.
