The soleal line, also known as the popliteal line (in older texts), is a prominent ridge on the posterior surface of the tibia. It is the site of many muscle origins and insertions, such as those of popliteus muscle, soleus muscle, flexor digitorum longus muscle, and tibialis posterior muscle.
It features a bony ridge called the soleal line. The line crosses this surface diagonally and eventually blends with the medial border of the tibia. Distal Tibia and its Bony Landmarks At the distal end, the tibia widens and appears rectangular in cross-section. It has two bony landmarks, the medial, malleolus, and fibular notch. 1.
The soleal line is a diagonal bony ridge that is located in the upper portion of the posterior surface of tibia. It is oriented downward and medially.Above the soleal line, the triangular region of the posterior surface of tibia serves as the point of origin for the popliteus muscle.The soleal line gives rise to the soleus muscle and the fascial coverings of the soleus and popliteus muscles ...
Description The soleal (popliteal) line is the rough ridge found on the proximal half of the posterior surface of tibia. It extends inferomedially from the fibular articular facet to the medial border of tibia. It provides an origin site for the soleus muscle, and an attachment site for the transverse intermuscular septum of leg.
The soleus muscle arises from the soleal line on the dorsal surface of the tibia, medial border of the tibia, head of the fibula, and posterior border of the fibula. Part of the fibers arises from the tendinous arch of the soleus, which spans between the tibia and fibula and arches over the popliteal vessels and tibial nerve.
