Overview of the calcaneus

The video tutorial explores the calcaneus, the largest bone in the foot, known as the heel bone. It is located in the posterior foot, inferior to the talus, and plays a crucial role in weight bearing and stability. The calcaneus serves as a lever for the Soleus and gastrocnemius muscles, which attach via the Achilles tendon. The bone's structure includes a concavo-convex shape and features like the calcaneal sulcus and perineal tubercle. It articulates with the talus and cuboid bones, possessing three articular facets for the talus. The calcaneus provides ample surface area for muscle attachments, including the gastrocnemius, Soleus, and various extensor and abductor muscles.
