Overview
A bunion is the enlargement of the joint at the base of the big toe. It occurs as a result of the misalignment of the bones of the big toe. This leads to stretching of the ligaments and tendons around the big toe joint and causes soft tissue over the joint to become inflamed and painful. There may be additional bone formation (exostosis) in the joint and the skin around the joint may become red and tender. Over time the cartilage in the joint can break down, leading to arthritis.
Causes
Foot problems typically develop in early adulthood and get worse as the foot spreads with aging. For many people, bunions run in the family. They may be just one of several problems due to weak or poor foot structure. Bunions sometimes develop with arthritis. In people with leg length discrepancies, bunions usually form in the longer leg. Women are especially prone to developing bunions. Years of wearing tight, poorly fitting shoes especially high-heeled, pointed shoes can bring on bunions. Such shoes gradually push the foot bones into an unnatural shape.
Symptoms
While bunions may be considered cosmetically undesirable, they are not necessarily painful. In cases where the individual has minor discomfort that can be eased by wearing wider shoes made of soft leather and/or with the aid of spacers-padding placed between the toes to correct alignment-further treatment may not be necessary. (Anti-inflammatory agents can be used to alleviate temporary discomfort at the site of the bursa.) For those who continue to experience pain on a daily basis and who cannot wear most types of shoe comfortably, surgical treatment may be the best choice.
Diagnosis
Before examining your foot, the doctor will ask you about the types of shoes you wear and how often you wear them. He or she also will ask if anyone else in your family has had bunions or if you have had any previous injury to the foot. In most cases, your doctor can diagnose a bunion just by examining your foot. During this exam, you will be asked to move your big toe up and down to see if you can move it as much as you should be able to. The doctor also will look for signs of redness and swelling and ask if the area is painful. Your doctor may want to order X-rays of the foot to check for other causes of pain, to determine whether there is significant arthritis and to see if the bones are aligned properly.
Non Surgical Treatment
Podiatrists will treat bunions conservatively, using paddings and orthotics, which are devices that are made to protect the joint or deviate pressure away from it. Sometimes bunions will develop overlying callus or corns. These can be removed by a podiatrist, but if the area is irritated again by wearing ill-fitting footwear, the corn will grow back. Most people with this condition have flat feet, so arch supports are often recommended.
Surgical Treatment
If the bunion symptoms does not respond to the conservative measures or if the bunion has progressed past a threshold where these measures are not effective, bunion surgery may be necessary to correct alignment and remove the bunion. A large range of types of surgical procedures for bunions are available and the choice will depend on things like what bone or bones are involved, the angular relationship between the different bones, the amount of damage to the joint and the presence of deformities other than the bunion.
