What is the calcaneus?

Our heel bone is also known as the calcaneus, and it is the biggest bone in the foot. On the back of the calcaneus, the gastrocnemius, plantaris, and soleus attach as the Achilles Tendon and are very important for us to walk and run. On the bottom of the calcanues, there are also several muscles that attach and are important for various foot functions. The plantar fascia also attaches on the bottom of the heel bone, and this is a common area of the foot that becomes inflamed in patients, requiring a podiatry visit.
