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.
High heels can exacerbate a potential bunion problem because they tip the body?s weight forward, forcing the toes into the front of the shoe. This may help to explain why bunions are 10 times more common in women than in men. People in occupations such as teaching and nursing, that involve a lot of standing and walking, are susceptible to bunions. Ballet dancers, whose feet suffer severe repetitive stress, are also amongst those who experience bunions. Women can sometimes develop bunions and other foot problems during pregnancy because hormonal changes loosen the ligaments and flatten the feet. Bunions are also associated with arthritis, which damages the cartilage within the joint.
Just because you have a bunion does not mean you have to have pain. There are some people with very severe bunions and no pain and people with mild bunions and a lot of pain. Symptoms for a bunion may include pain on the inside of your foot at the big toe joint. Swelling on the inside of your foot at the big toe joint. Redness on the inside of your foot at the big toe joint. Numbness or burning in the big toe (hallux). Decreased motion at the big toe joint. Painful bursa (fluid-filled sac) on the inside of your foot at the big toe joint. Pain while wearing shoes, especially shoes too narrow or with high heels. Joint pain during activities. Other conditions which may appear with bunions include corns in between the big toe and second toe. Callous formation on the side or bottom of the big toe or big toe joint. Callous under the second toe joint. Pain in the second toe joint.
Diagnosis begins with a careful history and physical examination by your doctor. This will usually include a discussion about shoe wear and the importance of shoes in the development and treatment of the condition. X-rays will probably be suggested. This allows your doctor to measure several important angles made by the bones of the feet to help determine the appropriate treatment.
Non Surgical Treatment
If overpronation is diagnosed early enough, the mechanics of the feet can be adjusted using a prescription orthotic. If orthotics are worn consistently, many major foot deformities can be avoided such as bunions. Early detection is of paramount importance. When a bunion progresses and cannot be controlled by an orthotic, surgical correction may be a consideration. Many advances in bunion correction allow for surgical intervention to make healing and return to normal activities much easier than use of traditional bunion surgery.
If other treatments don?t help and your bunion is very painful, you may be referred to an orthopaedic or a podiatric surgeon for assessment. There are over 130 different operations that can be carried out to treat bunions. The simplest operations are called bunionectomies. The majority of the operations aim to correct the alignment of your big toe. This will narrow your foot and straighten out your big toe joint as much as possible. An operation won?t return your foot back to normal, but most people find that surgery reduces their symptoms and improves the shape of their foot. The operation your surgeon will advise you to have will depend on how severe your bunion is and whether or not you have arthritis.
The best way to reduce your chances of developing bunions is to wear shoes that fit properly. Shoes that are too tight or have high heels can force your toes together. Bunions are rare in populations that don?t wear shoes. Make sure your shoes are the correct size and that there's enough room to move your toes freely. It's best to avoid wearing shoes with high heels or pointy toes.
