Bunions are localized enlargements of bone and tissue on the sides and/or top of the joint at either the base of the big toe or smallest toe (bunionette). The common bunion is located at the base of the big toe (the first metatarsophalangeal joint).

When your big toe is angled towards the second toe, the deformity is called a bunion (hallux valgus). This causes a bump on the side at the base of the big toe. In addition there is often thickening of the skin and tissues next to the affected joint. The thickened skin and tissues may become inflamed, swollen and painful.

38. A bunion (hallux valgus) is a deformity of the base joint of the big toe. The cause is not clear in many cases. The deformity may cause the foot to rub on shoes, which may cause inflammation and pain. Good footwear is often all that is needed to ease symptoms.

Bunions: Picture, symptoms, diagnosis, treatment and prevention. A bunion is a bony, lumpy deformity of the joint at the base of the big toe. The bunion will start to make the big toe point towards the other toes on the foot. The medical name for bunions is hallux valgus.

The symptoms of a bunion include the following: 1  Development of a firm bump on the outside edge of the foot, at the base of the big toe. 2  Redness, swelling, or pain at or near the MTP joint. 3  Corns or other irritations caused by the overlap of the first and second toes. 4  Restricted or painful motion of the big toe.

Because a bunion occurs at a joint, where the toe bends during normal walking, your entire body weight rests on the bunion at each step. Bunions can be extremely painful. They are also vulnerable to excess pressure and friction from shoes and can lead to the development of calluses.

Bunions. A bunion is a “bump” on the joint at the base of the big toe —the metatarsophalangeal (MTP) joint—that forms when the bone or tissue at the big toe joint moves out of place. The toe is forced to bend toward the others, causing an often painful lump of bone on the foot. Because this joint carries a lot of the body's weight while walking, bunions can cause extreme pain if left untreated. The MTP joint itself may become stiff and sore, making even the wearing of shoes difficult or impossible.

Introduction. A bunion is a bony deformity of the joint at the base of the big toe. The medical name is hallux valgus. The main sign of a bunion is the big toe pointing towards the other toes on the same foot, which may force the foot bone attached to it (the first metatarsal) to stick outwards. Other symptoms may include: 1  a swollen, bony bump on the outside edge of your foot.

The enlargement is often a combination of bone and joint malalignment in combination with tissue inflammation. The common bunion is frequently associated with an inward displacement deformity of the big toe that is medically referred to as a hallux abducto valgus deformity.

Even though bunions are obvious from the pain and unusual shape of the big toe, further diagnosis is wise. A doctor will usually take X-rays to determine the extent of the deformity. Blood tests may be advised to see if a type of arthritis may be causing the pain.
