GUSMAO, Luiz Carlos Buarque de; SOUSA RODRIGUES, Célio Fernando de y MARTINS, Josefa Sileda. Plantaris Muscle in Brazilian Individuals. Int. J. Morphol. [online]. 2011, vol.29, n.2, pp. 344-346. ISSN 0717-9502. http://dx.doi.org/10.4067/S0717-95022011000200006.
The aim of this study was to obtain more detailed information on the plantar muscle, which may provide a greater understanding of their presence, their morphology, their distal insertion, the path of its tendon, and the extent of the muscle and tendon, facilitating its removal for use in grafts. We performed 60 dissections of the lower limbs of adult cadavers in formaldehyde 10%. The plantar muscle was present in 57/60 of the cases (95%). In the 100% of the cases the muscle has a fusiform shape. The length of the muscle ranged from 7.0 cm to 13.7 cm. The length of the tendon ranged between 25.5 cm to 40 cm. The trajectory of the tendon was oblique in 82.46% between the medial gastrocnemius and soleus muscles, located in the remainder of its trajectory, medially to the calcaneous tendon. In 17.54% of the remaining cases the plantar tendon, after passing between the gastrocnemius and soleus muscles, it separated to move in the direction of the anterior calcaneal tendon. The muscle had its distal insertion in 79% on the medial calcaneal tendon. In 21% remaining cases, the insertion was in various locations such as on the soleus muscle, the flexor retinaculum and joint capsule of ankle joint.
