Peroneal Retinaculum Proximal

The peroneal retinaculum proximale (retinaculum musculorum fibularium proximale) is a structure that holds the peroneal muscles in place and prevents them from dislocating.

The peroneal muscles are a group of muscles that are located on the back of the lower leg and are responsible for the lateral movement of the foot. They attach to the fibula and are held in place by the peroneal retinaculum.

The peroneal retinaculum consists of two parts: proximal and distal. The proximal part is located at the level of the ankle and consists of ligaments and tendons that connect the fibula to the other bones of the foot. The distal part is at the level of the knee and consists of tendons that attach to the peroneal muscles.

When the peroneal muscles contract, they pull on the retinaculum, which can cause the fibula to dislocate. To prevent this, the peroneal retinaculum acts as a latch that holds the fibula bones in place.

In the event of injury or illness, the retinaculum can be damaged, which can cause dislocation of the fibulas and other problems. Therefore, it is important to monitor the condition of the peroneal retinaculum and, if necessary, carry out treatment.



The fibular retinaculum is a connective tissue formation that connects the lateral malleolus and the lateral meniscus of the knee joint. According to its function, the retinaculum is classified as a type of stabilizing structure. These tissues consist of an inextensible serrated retainer for the peroneal tendon and its muscle sheaths.
