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 a common problem experienced mostly by women. The deformity can develop from an abnormality in foot function, or arthritis, but is more commonly caused by wearing improper fitting footwear. Tight, narrow dress shoes with a constrictive toe box (toe area) can cause the foot to begin to take the shape of the shoe, leading to the formation of a bunion. Women who have bunions normally wear dress shoes that are too small for their feet. Their toes are squeezed together in their shoes causing the first metatarsal bone to protrude on the side of the foot. It is important for men and women to realize that wearing dress shoes and boots, which are tapered in the toe area, can cause the bunion to worsen to the point where surgery is necessary. 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
Clinical findings are usually specific. Acute circumferential intense pain, warmth, swelling, and redness suggest gouty arthritis (see Gout) or infectious arthritis (see Acute Infectious Arthritis), sometimes mandating examination of synovial fluid. If multiple joints are affected, gout or another systemic rheumatic disease should be considered. If clinical diagnosis of osteoarthritic synovitis is equivocal, x-rays are taken. Suggestive findings include joint space narrowing and bony spurs extending from the metatarsal head or sometimes from the base of the proximal phalanx. Periarticular erosions (Martel sign) seen on imaging studies suggest gout. Non Surgical Treatment
A range of treatments is available for bunions, including painkillers, modifying footwear, orthotics, such as insoles, bunion pads and toe spacers. Surgery may be considered if a person's symptoms are severe and do not respond to non-surgical treatment. The type of surgery used will depend on the level of deformity, the severity of any other associated symptoms, the patient's age and any other associated medical conditions. Bunion surgery is usually effective, with up to 85% of cases resulting in improvement to symptoms. However, the deformity can sometimes return after bunion surgery. Surgical Treatment
When the pain of a bunion interferes with daily activities, and conservative treatment has been completed it's time to discuss surgical options. Foot Mechanics has excellent relationships with many Orthopaedic Surgeons, who are the specialists who perform bunion surgery. Because bunions are caused by faulty foot mechanics surgery can improve the look of your feet by removing the ?bump? but if the underlying mechanics are not addressed then the bunion is likely to return. For this reason orthotics are used post-surgery to prevent the return of bunions.
