Arch Pain

Pain across the bottom of the foot at any point between the heel and the ball of the foot is often referred to as “arch pain.” Although this description is non-specific, most arch pain is due to strain or inflammation of the plantar fascia (a long ligament on the bottom of the foot). This condition […]

Ankle Sprain

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 […]

Ankle Pain

Ankle pain is often due to an ankle sprain but can also be caused by ankle instability, arthritis, gout, tendonitis, fracture, nerve compression (tarsal tunnel syndrome), infection and poor structural alignment of the leg or foot. Ankle pain can be associated with swelling, stiffness, redness, and warmth in the involved area. The pain is often described as an intense dull […]

Common Disorders of the Achilles Tendon

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 […]

Chronic Ankle Instability

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, […]

Posterior Tibial Tendon Dysfunction (PTTD)

What Is PTTD? The posterior tibial tendon serves as one of the major supporting structures of the foot, helping it to function while walking. Posterior tibial tendon dysfunction (PTTD) is a condition caused by changes in the tendon, impairing its ability to support the arch. This results in flattening of the foot. PTTD is often […]

Achilles Tendon Rupture

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 […]

Accessory Navicular Syndrome

What is the Accessory Navicular? The accessory navicular (os navicularum or os tibiale externum) is an extra bone or piece of cartilage located on the inner side of the foot just above the arch. It is incorporated within the posterior tibial tendon, which attaches in this area.   An accessory navicular is congenital (present at […]
