More than one-third of women in America have bunions, a common deformity often blamed on wearing tight, narrow shoes and high heels. Bunions may occur in families, but many are from wearing tight shoes, and nine out of 10 bunions happen to women. Too-tight shoes can also cause other disabling foot problems such as corns, calluses and hammer toes. Causes
Bunions can be caused by improper footwear. Genetics. Foot injuries. Congenital deformities. Medical conditions such as arthritis. Stress on feet. Bunions are mainly caused by genetics. The bunion itself is not inherited, but the person?s hereditary foot type and gait pattern makes them more prone to developing bunions.You can also begin to develop bunionsby wearing shoes that are too tight or too small. When you wear shoes of this nature, your toes are squeezed together. Bunions are not caused by crowding of the toes, but wearing tight shoes can worsen the condition and cause symptoms to appear sooner. Some people are born with birth defects that put them at higher risk for developing bunions.
Symptoms
With the positional change of the hallux, pain is a common occurrence. As the foot goes through the gait cycle the hallux plays an integral role as the body's weight transmits through during propulsion. With this in mind, it easy to see how the change in the hallux joints (metatarsal phalangeal joint and the proximal interphalangeal) would cause joint narrowing and early degeneration of the articular cartilage. In addition, two small bones (ossicles) found underneath just behind the joint will start placing extra pressure on the metatarsal. Along with bony changes, there are many soft tissue changes as the hallux and metatarsal reposition, which causes added strain to other bony structures and can accelerate the problem.
Diagnosis
When an x-ray of a bunion is taken, there is usually angulation between the first metatarsal bone and the bones of the big toe. There may also be angulation between the first and second metatarsal bones. These angular irregularities are the essence of most bunions. In general, surgery for bunions aims to correct such angular deformities.
Non Surgical Treatment
The choice of treatment for a bunion lies between non-operative (conservative) and operative treatment. Conservative treatment for a bunion means either wearing wider fitting shoes or shoes with softer leather or using some form of a spacer between the big toe and 2nd toe (or alternatively some form of splint to keep the great toe away from the 2nd toe). The spacers or splintage may apparently straighten the bunion but they make no difference to the width of the foot, and the splaying of the 1st and 2nd metatarsals which occur with a bunion deformity. Therefore this type of treatment will not improve the main pain in a bunion which occurs due to the width of the forefoot. An arch type support orthotic may be useful if a bunion is associated with a flatter foot. If you have a bunion this is however just one other thing to get into a shoe with an already wide foot.
Surgical Treatment
If the conservative options fail, your doctor will determine the best surgical procedure based on the severity of your condition. The most common surgical procedure is a bunionectomy, which includes removing swollen tissue from around your big toe joint. Removing part of the bone to straighten your big toe. Realigning the metatarsal bone to reduce angular deformity. Joining the bones in a corrected position to permanently correct the deformity. Most people can get up and walk around the day after bunion surgery, but full recovery can occasionally take up to eight weeks or more. Doctors stress the importance of wearing proper shoes, especially after treatment, to prevent recurrence. If you are at higher risk or prone to bunions, you may not be able to avoid recurrence.
Prevention
Make better shoe choices. If you?re a woman, avoid high-heeled footwear whenever possible (at the very least, choose shoes with heels lower than two inches), and make sure all your footwear has a wide, deep toe box. Whether man or woman, if you?re trying on shoes and your toes feel ?squished? or crowded by a particular shoe, reject that style and try another, or go for a larger size. You don?t need to invite trouble. In general, shoes that come to a point at the toe are bad news, as they tend to push the toes together into an overlapping pattern. Shoes with rocker soles will unload pressure on the bunion area. Examine your feet regularly. Note any redness, swelling or discoloration. Flex your toes and check for any stiffness. If there is any, think back to what you?ve worn or done in the past few days. If the condition persists more than a few days, or worsens, a visit to the podiatric physician is in order.
