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
Bunions are most often caused by an faulty foot mechanics. It is not the bunion itself that is inherited, but certain foot types that make a person prone to developing a bunion. Although wearing shoes that crowd the toes won't actually cause bunions in the first place, it sometimes makes the deformity get progressively worse. That means you may experience symptoms sooner.
Symptoms
Signs and symptoms of a bunion include the base of the big toe is swollen and sticks out. The big toe is often bent towards the other toes, and sometimes the second toe is pushed to overlap the third toe. Skin around the big toe joint is red and sore. Thickened skin at the base of the big toe. Pain in the big toe or foot. Wearing shoes is painful. Pain or difficulty when walking.
Diagnosis
Your doctor will be able to diagnose a bunion by asking about your symptoms and examining your feet. You may also have blood tests to rule out any other medical conditions, such as rheumatoid arthritis or gout, although this is rare. Your doctor may refer you to a podiatrist or chiropodist (healthcare professionals who specialise in conditions that affect the feet).
Non Surgical Treatment
Early treatment of bunions is centered on providing symptomatic relief. Switching to a shoe with a rounder, deeper toe box and made of a softer more pliable leather will often provide immediate relief. The use of pads and cushions to reduce the pressure over the bone can also be helpful for mild bunion deformities. Functional foot orthotics, by controlling abnormal pronation, reduces the deforming forces leading to bunions in the first place. These may help reduce pain in mild bunion deformities and slow the progression of the deformity. When these conservative measures fail to provided adequate relief, surgical correction is indicated.
Surgical Treatment
Bunion surgery is most often performed as an out-patient, this means you go home that same day. It will likely be done at a hospital or out-patient (ambulatory) surgery center. The anesthetic choices with bunion surgery are local with sedation, spinal or general anesthesia. You wouldn?t expect that a small bunion would be treated exactly the same as a large one. Over the years, surgeons have developed dozens of methods to surgically correct bunions. But don?t worry because only a handful of methods are used today. With most bunion surgeries today, the procedure involves a combination of soft-tissue rebalancing of ligaments and tendons as well as bone work to re-align the foot structure. You may have heard people say they had their ?bunion shaved.? In most cases, the surgery often involves much more than simply shaving the bunion. The shaving part of the procedure is called an ?exostectomy? and often performed in conjunction with other methods.
