Overview
A bunion is a painful deformity of the joint where the bones of the foot and the big toe meet. The enlargement of the bone and tissue around this joint is known as a bunion or hallux valgus. Symptoms of a bunion include a swollen bursal sac, a bony deformity on the side of the great toe joint, tender and swollen tissues surrounding the deformity, and displacement of the big toe, which may turn inward.
Causes
Bunions occur with greater regularity in women than men, and they may sometimes run in families. You may also have an increased likelihood of bunions if you are born with certain bone abnormalities in your feet. Factors that may increase your chances of developing a bunion include long-term use of narrow-toed and/or high-heeled footwear. Arthritis. Toe trauma. Laxity of your connective tissues (ligament laxity). Limb length inequalities. Genetics. Certain foot problems (e.g. flatfoot, over-pronation, etc.).
Symptoms
The main problem is usually the pressure of the shoe over the bony prominence, which causes discomfort or pain. Sometimes the skin over the lump becomes red, blistered or infected. The foot may become so broad that it is difficult to get wide enough shoes. The big toe sometimes tilts over so much that it rubs on the second toe, or pushes it up out of place so it presses on the shoe. Also, the big toe does not work as well with a bunion, and the other toes have to take more of the weight of the body as you walk. This can cause pain under the ball of the foot ("metatarsalgia"). Sometimes arthritis develops in the deformed joint, causing pain in the joint.
Diagnosis
X-rays are the best way to determine the amount of deformity of the MTP joint. Blood work may be required to rule out other diseases that may be associated with bunions such as rheumatoid arthritis. Other tests such as bone scans or MRI's are not usually required.
Non Surgical Treatment
Nonsurgical treatments such as rest and wearing loose (wider) shoes or sandals can often relieve the irritating pain of bunions. Walking shoes may have some advantages, for example, over high-heeled styles that pressure the sides of the foot. Anti-inflammatory medications, such as acetylsalicylic acid (aspirin, Ecotrin), ibuprofen (Advil, Children's Advil/Motrin, Medipren, Motrin, Nuprin, PediaCare Fever) and naproxen (Anaprox, Naprelan, Naprosyn, Aleve), can help to ease inflammation as well as pain. Local cold-pack application is sometimes helpful as well. To reduce tension on the inner part of the joint of a bunion, stretching exercises are sometimes prescribed. Depending on the structure of the foot and severity of the bunion, custom insole orthotics can slow the progression of the bunion and address underlying biomechanical causes. Inflammation of the joint at the base of the big toe can often be relieved by a local injection of cortisone. Any signs of skin breakdown or infection can require antibiotics. When the measures above are effective in relieving symptoms, patients should avoid irritating the bunion again by optimizing footwear and foot care.
Surgical Treatment
When these above measures no longer help to relieve the pain in the big toe, surgery to correct the bunion deformity is considered. Numerous surgical procedures have been recommended for bunions. What is most critical is that the type of deformity is carefully evaluated, because one bunion surgery cannot be used for all types of bunions. If the big toe joint is rotated out of place, the joint must be rotated back in place for the procedure to work. Conversely, a bunion can occur with the big toe still ?in place.? If surgery is considered, the bunion must be corrected with the toe joint left in its current position. In other words, one type of bunion repair does not work for everyone. In all types of bunion repairs, ligaments and tendons (soft tissues) around the big toe joint are reconstructed, to allow the toe to be straightened. Most bunion procedures also require cutting the metatarsal bone, which is then fixed with metal screws to hold the bone in position until it heals. It usually takes 2 to 4 months to fully recover from bunion surgery, which is why it is always the last course of treatment.
