Peroneal Retinaculum Distal

The distal peroneal retinaculum (retinaculum musculorum fibularium distale, pna) is a fibrous structure located in the distal part of the lower leg. It is the fascia that holds the tendons of the muscles that run through the lateral ankle to the foot.

The distal peroneal retinaculum secures the peroneal tendons (abductor hallucis, extensor digitorum longus, and extensor hallucis longus) to prevent them from shifting during foot and ankle movements. This ensures correct biomechanics of the foot when walking and running.

Thus, the distal peroneal retinaculum plays an important role in the functioning of the ankle and foot. Damage to this structure can lead to impaired motor activity and pain.



The peroneus distal retinaculum (or simply “distal fibular retinaculum”) is an anatomical structure that is located in the lower part of the lower leg and prevents excessive extension of the fibula. It consists of several layers of connective tissue, including fascia, tendons and ligaments, which attach to the peroneus muscle and bones of the lower leg.

The distal fibular retinaculum is a structure that limits the movement of the fibula and protects it from injury and damage. It plays an important role in maintaining stability and balance in the lower extremities.

For injuries or illnesses involving the fibula, it may be necessary to undergo surgery or other treatments to restore function of the distal fibula retinaculum. In such cases, the doctor may recommend surgery to restore the integrity of the structure or replace it with an artificial replacement.

Overall, the distal fibular retinaculum plays an important role in protecting and maintaining lower extremity function. However, if injuries or illnesses related to this region occur, treatment may include surgery or other methods to restore its function.
