What Is the Achilles Tendon? A tendon is a band of tissue that connects a muscle to a bone. The Achilles tendon runs down the back of the lower leg and connects the calf muscle to the heel bone. Also called the “heel cord,” the Achilles tendon facilitates walking by helping to raise the heel…

What Is Chronic Ankle Instability? Chronic ankle instability is a condition characterized by a recurring “giving way” of the outer (lateral) side of the ankle. This condition often develops after repeated ankle sprains. Usually the “giving way” occurs while walking or doing other activities, but it can also happen when you’re just standing. Many athletes,…

What Is Charcot Foot? Charcot foot is a condition causing weakening of the bones in the foot that can occur in people who have significant nerve damage (neuropathy). The bones are weakened enough to fracture, and with continued walking the foot eventually changes shape. As the disorder progresses, the joints collapse and the foot takes…

What is Capsulitis of the Second Toe? Ligaments surrounding the joint at the base of the second toe form a “capsule,” which helps the joint to function properly. Capsulitis is a condition in which these ligaments have become inflamed. Although capsulitis can also occur in the joints of the third or fourth toes, it most…

A callus is a thickened area of skin on the foot caused by pressure and repeated rubbing, such as from a shoe or sock. The rubbing causes the skin to produce a layer of protective skin (a callus). Calluses vary in size, and can become painful. There are a number of treatments for painful calluses.…

What is the Calcaneus? The calcaneus, also called the heel bone, is a large bone that forms the foundation of the rear part of the foot. The calcaneus connects with the talus and cuboid bones. The connection between the talus and calcaneus forms the subtalar joint. This joint is important for normal foot function. The…

What Is Calcaneal Apophysitis? Calcaneal apophysitis is a painful inflammation of the heel’s growth plate. It typically affects children between the ages of 8 and 14 years old, because the heel bone (calcaneus) is not fully developed until at least age 14. Until then, new bone is forming at the growth plate (physis), a weak…

Even though bunions are a common foot deformity, there are misconceptions about them. Many people may unnecessarily suffer the pain of bunions for years before seeking treatment.   What is a Bunion? A bunion (also referred to as hallux valgus or hallux abducto valgus) is often described as a bump on the side of the…

Brachymetatarsia is a condition in which one of the bones in the front of the foot is significantly shorter than the others. Although it may affect any of the five metatarsals, it most commonly affects the fourth metatarsal. Looking at the foot, it might appear that the fourth toe itself is shorter than the adjacent…

What Is an Ankle Sprain? An ankle sprain is an injury to one or more ligaments in the ankle, usually on the outside of the ankle. Ligaments are bands of tissue – like rubber bands – that connect one bone to another and bind the joints together. In the ankle joint, ligaments provide stability by…
