Foot and Ankle

The Achilles tendon is the largest tendon in the body. It connects the two main calf muscles - the gastrocnemius and soleus - to the heel bone (the calcaneus). Common injuries of the Achilles tendon include tendonitis (inflammation), tendinosis (degeneration), and rupture.

Ligaments are fibrous, elastic bands of tissue that connect and stabilize the bones. An ankle sprain is a common, painful injury that occurs when one or more of the ankle ligaments is stretched beyond the normal range of motion. Sprains can occur as a result of sudden twisting, turning or rolling movements.

This deformity affects the joint at the base of the big toe. It is a bony bump beneath the skin on the inner side of the foot. A bunion starts small, but over time it can grow to become very large. Bunions are more common in women.

This disorder is a deformity that typically affects one or more of the small toes. In many cases, all four small toes are affected. The toes bend up at the first joint and then curl down toward the floor, giving the appearance of a claw or talon.

This condition is a break in the heel bone, called the calcaneus, which forms the back of the foot. This bone supports the foot and is important for normal walking.

This condition occurs when the talus, a bone that connects the foot and ankle, develops a fracture from a severe impact or fall. The talus is an important bone of the foot, as it aids in walking on uneven ground and in weight transfer across the ankle joint.

This condition, also known as hallux limitus, is a form of degenerative arthritis that affects the joint at the base of the big toe. It causes pain and stiffness in the big toe, which increases over time as the toe becomes increasingly rigid and hard to bend.

This condition is a deformity in which a toe bends downward at the middle joint. The second toe is the one most likely to be affected, but this deformity can occur in other toes as well. Sometimes, more than one toe is affected.

This condition is a sprain of one or more of the ligaments that hold the tibia and fibula together at the ankle. This joint, called the ankle syndesmosis, is made up of ligaments on the front and rear of the ankle, and in the space between the tibia and fibula.

This condition is a thickening of the nerve sheath that surrounds a nerve in the ball of the foot. It most commonly develops between the third and fourth toes. It also commonly occurs between the second and third toes.

This condition is an injury to the navicular, one of the tarsal bones of the midfoot. This type of injury is common in athletes, particularly those who participate in high-impact sports that require jumping, sprinting and sudden directional changes. Track and field athletes are particularly susceptible.

Plantar fasciitis is an irritation of the plantar fascia. This thick band of connective tissue travels across the bottom of the foot between the toes and the heel. It supports the foot's natural arch. It stretches and becomes taut whenever the foot bears weight.

Stress fractures are small cracks that can occur in a bone because of overuse or activities that place high stress on the structures of the foot and ankle.
