Amniotic Band Syndrome (ABS) is an uncommon congenital abnormality that causes entrapment of fetal parts (usually a limb or digits) in fibrous amniotic bands while in utero. It can result in disfigured feet. ABS affects about one in every 1,200 births and is believed to be the cause of 178 in 10,000

What are Bunions? Also known as a hallux valgus, bunions are bony bumps that form at the base of the big toe. Bunions are a common toe disorder that affects about a third of all adults in the US. They form due to the big toe pointing inward to the other toes of your feet. As a result, the metatarsophalangeal

Claw toe is caused by nerve damage from diseases like diabetes or alcoholism, which can weaken muscles in the foot. The term stems from the toes' appearance—toes that look like claws digging down into the soles. Claw toe may lead to the formation of painful calluses. Claw toe worsens without treatment

Clubfoot is one of the most common, non-life threatening, major birth defects among infants globally. Approximately one in every 1,000 newborns has clubfoot. Of those, one in three have both feet clubbed. The exact cause is unknown. Two out of three clubfoot babies are boys. Clubfoot is twice as likely

Dysplasia, also known as epiphysealis hemimelica, is a disorder that affects the bone joints. It is characterized by overgrowth of the cartilage on the end of one or more of the long bones (carpal or tarsal bones) in the hand or foot. Usually only one limb is involved. Dysplasia may cause limbs that

Enchondromas are small benign tumors made up of cartilage that form in the bone beneath the toenail. Enchondromas are the most common bone tumors of the hands and feet and usually are painless. The tumor can involve large portions of the bones, causing thinning of the cortex. This can weaken the bone

Flat feet are a common condition of the foot structure. In infants and toddlers, prior to walking, the longitudinal arch is not developed, and flat feet are normal. Most feet are flexible and an arch appears when children begin standing on their toes. The arch continues to develop throughout childhood,

Gordon Syndrome is an extremely rare disorder that belongs to a group of genetic disorders known as the distal arthrogryposes. These disorders typically involve stiffness and impaired mobility of certain joints of the lower arms and legs (distal extremities) including the knees, elbows, wrists, and/or

Haglund's Deformity (also known as pump bump or retrocalcaneal bursitis) is a painful enlargement on the back of the heel bone that becomes irritated by shoes. It normally appears as a red, painful, and swollen area in the back of the heel bone. Women tend to develop the condition more than men because

Hallux Limitus is a condition that results in stiffness of the big toe joint. It is normally caused by an abnormal alignment of the long bone behind the big toe joint, called the first metatarsal bone. Left untreated, Hallux Limitus can cause other joint problems, calluses, and/or diabetic foot ulcers.

An unmovable big toe, known as Hallux Rigidus, is the most common form of arthritis in the foot.   Hallux Rigidus occurs as a result of wear-and-tear injuries, which wear down the articular cartilage, causing raw bone ends to rub together. A bone spur, or overgrowth, may develop on the top of the

Hallux Varus is a condition in which the big toe points away from the second toe. It is a possible complication from bunion surgery. The condition has been linked to a number of other causes, including congenital deformity, tight or short abductor hallucis tendons, trauma, injury, or an absence or surgical

Hammertoe is a deformity of the second, third, or fourth toes. In this condition, the toe is bent at the middle joint, causing it to resemble a hammer. Left untreated, hammertoes can become inflexible and require surgery. People with hammertoe may have corns or calluses on the top of the middle joint

Jackson-Weiss Syndrome (JWS) is a rare genetic disorder characterized by foot abnormalities. Symptoms include abnormally broad big toes, webbing of the skin between the second and third toes, an inward angling of the toes, and/or malformation or fusion of certain bones within the feet. Jackson-Weiss

Mallet toes are deformities caused by bone and muscle imbalances that become exaggerated in people with active lifestyles. Arthritis can also lead to mallet toes. Mallet toes can cause extreme discomfort and may be aggravated if restrictive or improperly fitting footwear is worn for a prolonged period

Pain in the area between the arch and toes, or ball of the foot, is generally called metatarsalgia. The pain usually centers on one or more of the five bones (metatarsals) in this mid-portion of the foot. Also known as dropped metatarsal heads, metatarsalgia can cause abnormal weight distribution due

Osteomyelitis is a type of bacterial bone infection that moves from acute to chronic phases quickly. The infection usually begins in another part of the body and spreads to the bone via blood. Traumatic injury, frequent medication injections, the use of a prosthetic device, and some surgical procedures

Overlapping toes are characterized by one toe lying on top of an adjacent toe. The fifth toe is the most commonly affected. Overlapping toes may develop in the unborn fetus. Passive stretching and adhesive taping is most commonly used to correct overlapping toes in infants, but the deformity usually

Peroneal tendons support two important foot muscles (Peroneus Brevis and Peroneus Longus) that originate on the outside of the calves. These two muscles allow you to roll to the outside of your foot while standing. Peroneal tendons are also called stirrup tendons because they help hold up the arch of

The posterior tibial tendon starts in the calf, stretches down behind the inside of the ankle, and attaches to bones in the middle of the foot. This tendon helps hold the arch up and provides support when stepping off on your toes when walking. If it becomes inflamed, over-stretched or torn, it can cause

Sesamoids are small bones that are connected only to tendons or are embedded in muscle. This structure appears in only a few places in the human body, one of which is the foot. Two very small sesamoids (about the size of a kernel of corn) are found in the underside of the forefoot near the big toe—one

Bone spurs are a very common foot problem. In the feet, they develop most frequently in the heel, near the toes, and on top of the big toe joint. The spurs are small outgrowths of bone. In and of themselves, they are generally harmless. However, their location may cause friction or irritation from shoes

Tarsal coalition is a bone condition that causes decreased motion or absence of motion in one or more of the joints in the foot. The bones found at the top of the arch, the heel, and the ankle are referred to as the tarsal bones. A tarsal coalition is an abnormal connection between two of the tarsal
