Overview
A bunion is a firm, fluid-filled pad overlying the inside of the joint at the base of the big toe (metatarsophalangeal joint). The pad (bursa), which may get larger and stick out, can become inflamed and painful. Bunions may run in families, but many result from wearing tight shoes. Nine out of 10 bunions are developed by women. Nine out of 10 women wear shoes that are too small. Tight shoes also can cause other disabling foot problems like corns, calluses and hammertoes.
Causes
Despite the popular belief, wearing high heels and too-narrow shoes does not cause bunions. Wearing them can irritate, aggravate, or accelerate the formation of the bunion, but are not the root cause. Bunions are more commonly inherited, if your parents or grandparents had bunions, you may also get one. Bunions can also be caused by trauma or injury to the joints, ligaments, or bones of the foot.
Symptoms
The symptoms of hallux valgus usually center on the bunion. The bunion is painful. The severe hallux valgus deformity is also distressing to many and becomes a cosmetic problem. Finding appropriate shoe wear can become difficult, especially for women who want to be fashionable but have difficulty tolerating fashionable shoe wear. Finally, increasing deformity begins to displace the second toe upward and may create a situation where the second toe is constantly rubbing on the shoe.
Diagnosis
Physical examination typically reveals a prominence on the inside (medial) aspect of the forefoot. This represents the bony prominence associated with the great toe joint ( the medial aspect of the first metatarsal head). The great toe is deviated to the outside (laterally) and often rotated slightly. This produces uncovering of the joint at the base of the big toe (first metatarsophalangeal joint subluxation). In mild and moderate bunions, this joint may be repositioned back to a neutral position (reduced) on physical examination. With increased deformity or arthritic changes in the first MTP joint, this joint cannot be fully reduced. Patients may also have a callus at the base of their second toe under their second metatarsal head in the sole of the forefoot. Bunions are often associated with a long second toe.
Non Surgical Treatment
There is a wide rage of treatment options for those who suffer from bunions. If the bunion is mild and does not require bunion surgery, resting the foot and avoiding excessive exercise or walking will help. Wearing shoes that have a wider toe opening, including sandals, can relieve the rubbing and irritation that comes along with more confining shoes. High-heeled shoes should be avoided as they push the big toe outward and can inflame the joint of a bunion. Anti-inflammatory medications (aspirin, ibuprofen, etc.) usually ease inflammation and target pain as well. If the bunion does become inflamed and irritated, application of an ice pack can reduce swelling and pain. If the inflammation because excessive, cortisone can be injected at the site of the bunion to reduce the swelling at the joint of the big toe.
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.
