Anatomy origins insertions. The sheath is runs in the retromalleolar sulcus on the fibula. They lie within the peroneal compartment located at the lateral fibular region.

Peroneal tendon disorders are a cause of hindfoot and lateral foot pain. The tendons are kept in place by the presence of a shallow groove on the posterior fibula the superior peroneal retinaculum spr which tethers the tendons to the fibula and a fibrocatilaginous lip which deepens the groove where it meets the retinaculum. The peroneal tendons curved arrow are in their normal position within a convex fibular groove but thinning and irregularity of the peroneal brevis tendon suggest impending longitudinal splits.

Peroneal tendon tears and tendonitis. The muscles are connected to bone by the tendons. The peroneal tendons are located in the foot attaching muscle to bone.

The muscle the longest and most superficial of the three peroneus muscles is attached proximally to the head of the fibula and its belly runs down most of this bone. When lowering the foot they can be easily seen forming the surface of the lateral leg. People who take part in a sport that involves repetitive ankle motion are most prone.

The two major peroneal muscles peroneus longus and peroneus brevis are situated on the outside of the leg just adjacent to the calf muscles. Normal variant anatomy in this region may include a peroneus quartus muscle a low lying peroneus brevis muscle belly or an os peroneum. They are misdiagnosed as a lateral ankle sprain most of the time.

Peroneal tendon syndromes practice essentials. In human anatomy the peroneus longus also known as fibularis longus is a superficial muscle in the lateral compartment of the leg and acts to evert and plantarflex the ankle. The peroneal tendons originate in the lateral compartment of the leg.
