A bunion is a deformity of the metatarsophalangeal (MTP) joint at the base of the big toe. A bunion develops when the first metatarsal bone of the foot turns outward and the big toe points inward (toward the other toes), causing the joint to jut out. A bunion is most likely to develop when susceptible feet are repeatedly squeezed into narrow, pointed-toe footwear. The big toe pushes against the other toes, sometimes diving over or under them. As a result, the base of the big toe ? the metatarsophalangeal (MTP) joint ? juts or angles out from the foot. Causes
Women tend to get bunions more than men. This could be due to the more restrictive footwear they wear, (such as high heels or narrow toe boxes which force the big toe towards the little toes) but women also tend to have looser ligaments, making them slightly more prone. You?re also more likely to get bunions if your parents or grandparents have them.
Symptoms
Bunions are an often painful condition that may become even more painful as extra bone and a fluid-filled sac grow at the base of your big toe. Some of the most frequently experienced signs and symptoms associated with bunions, besides pain, include redness in your affected area. Blistering over your bunion. Callus formation around your bunion. Bursitis. Nerve damage (numbness and/or sharp pains) in your involved area. Bunions may also cause pain within and below your first metatarsophalangeal, or MTP, joint. Your bunion may become further dislocated and unstable as it progresses and may overload your adjacent joints.
Diagnosis
Your doctor can identify a bunion by examining your foot. Watching your big toe as you move it up and down will help your doctor determine if your range of motion is limited. Your doctor will also look for redness or swelling. After the physical exam, an X-ray of your foot can help your doctor identify the cause of the bunion and rate its severity.
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.
Surgical Treatment
There is more than one way to surgically treat a bunion. While there are some general guidelines, some procedures work well for some Surgeons and poorly for others. Your Surgeon should consider the severity of your bunion, medical condition, lifestyle, and recuperation time when considering the surgical treatment.
Prevention
To help prevent bunions be sure your shoes don't cramp or irritate your toes. Choose shoes with a wide toe box - there should be space between the tip of your longest toe and the end of the shoe. Your shoes should conform to the shape of your feet without squeezing or pressing any part of your foot. Avoid pointy-toed shoes.
