WebIn Type B, the sesamoid is located at sites where tendons are angled about bony surfaces and separated from the underlying bone by a bursa (i.e., sesamoid of the peroneus longus tendon). The peroneus longus and brevis tendons pass beneath the fibula within the retromalleolar sulcus and are held in place by the superior peroneal retinaculum, then run beneath the inferior peroneal retinaculum at the It may cause pain on exercise. Blood supply of the soleus muscle is from peroneal artery proximally and the posterior tibial artery distally; Vascular supply of the soleus is from popliteal, posterior tibial, & peroneal vascular pedicles to the proximal muscle, peroneal pedicles to distal lateral belly, and segmental posterior tibial pedicles to distal medial belly; With distal pedicles from the posterior tibial artery ligated & based on proximal pedicles from the posterior tibial and peroneal arteries, muscle can be transposed medially or laterally to cover defects in middle third of the leg; Proximal vasculature arises directly from the popliteal vessels and can reliably carry all but the distal 4 to 5 cm of the muscle; Intramuscularly, vasculature of the soleus divides into a bipenniform segmental pattern; With this vascular pattern, either half of the soleus muscle can be used, leaving a functional hemisoleus muscle intact.
