A bunion is enlargement of bone or tissue that develops at the joint that connects your big toe to your foot. The bones, muscles, ligaments and tendons of your feet normally are well-balanced to distribute your body's weight while standing, walking and running. When the joint, called the metatarsophalangeal joint, or MTP joint, experiences abnormal, prolonged stress in terms of weight distribution or squeezing of the toes within the shoe, the result can be the deformity called a bunion. Generally, a bunion develops when, as a response to prolonged stress, your big toe begins bending toward your foot's smaller toes and puts pressure on your MTP joint, forcing it to bulge outward (the term "bunion" comes from the Latin word for "enlargement"). There is no "standard" bunion, however, but rather a complex range of joint, bone and tendon abnormalities that can cause variation in each bunion's make-up.
Perhaps the most frequent cause of bunion development is the wearing of shoes with tight, pointed toes, or with high heels that shift all of your body's weight onto your toes and also jam your toes into your shoes' toe boxes. It's estimated that more than 50 percent of women have bunions caused by high-heel shoes, and that nine out of 10 people who develop bunions are women. Bunions can also develop on your little toes, in which case they are called bunionettes or tailor's bunions.
Your bunion may not cause any symptoms. Or you may have pain in your big toe, red or irritated skin over the bunion, and swelling at the base of the big toe. The big toe may point toward the other toes and cause problems in other toes, such as hammer toe . A bunionette can cause similar symptoms at the base of the little toe.
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
Wide shoes with plenty of space for the toes are the first place to start. Along these lines, a shoe can be focally stretched directly over the painful bunion using a device known as a ?ball and ring? shoe stretcher. Additionally, numerous commercial bunion braces and splints are available to help keep the big toe in better alignment.
Bunions can cause pain and difficulty wearing certain shoes. When simple treatments don't relieve your symptoms, surgery may be considered for treatment of the bunion. What are the signs that surgery may be the right treatment for your bunion? In general, surgery is recommended only when pain from the bunion prevents a patient from wearing normal shoes. There is a common misconception that surgical treatments for a bunion are better and quicker than non-surgical treatments. Unfortunately, patients who rush into surgery may have unrealistic expectations, and may be unsatisfied with surgery.
