A Bunion is one of the most common foot ailments which usually occur near the joint at the base of the big toe. It is actually a bony protrusion which consists of excess or misaligned bone in the joint. Although they may develop on the fifth or little toe, bunions usually occur at the base of the big toe. In addition to causing pain, a bunion changes the shape of your foot, making it harder to find shoes that fit. The good news however, is that you don?t have to hobble for the rest of your life, bunions can be treated.
What causes bunions? This question is often answered by blaming shoes. But in fact, shoes only play a small role in developing bunions. Yes, shoes, especially high heels cause abnormal squeezing of your forefoot. This in turn to help promote a bunion. But if everyone who wore high heels shoes had a bunion, there would be a lot more then the 15% prevalence we see in the general population. As you can see from the flow chart, genetics plays the major role in development of bunion deformities. Genetics determines the way your foot functions. Are you flatfooted? Are your joints flexible or stiff? Do you have a high arch? Do you have tight muscles? These traits are determined by your genetic code. These characteristics then govern how your bones and joints move when you walk. As an example, if your joints are very flexible, this can cause an abnormal amount of instability in your forefoot when you walk. Over time, this abnormal motion will cause the a bunion to develop by allowing your first metatarsal to "drift" towards the mid-line of your body.
If a foot bunion is developing, you may experience some of these symptoms. Bulge or bump on the outside of the base of your big toe. Swelling. Redness. Soreness. Thickening of the skin in that location. Corns or calluses. Limited movement of your big toe. Persistent or periodic pain. The pain you experience may be mild or severe. It may become increasingly difficult to walk in your normal shoes. The pressure on your other toes can cause your toenails to grow inward or your smaller toes to become bent.
Bunions are readily apparent - the prominence is visible at the base of the big toe or side of the foot. However, to fully evaluate the condition, the foot and ankle surgeon may take x-rays to determine the degree of the deformity and assess the changes that have occurred. Because bunions are progressive, they don?t go away, and will usually get worse over time. But not all cases are alike - some bunions progress more rapidly than others. Once your surgeon has evaluated your bunion, a treatment plan can be developed that is suited to your needs.
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.
The aim of surgery is to correct the cause of the bunion and prevent it growing back. Which type of surgery your podiatric surgeon recommends will depend on the severity of your bunion. Because there are risks and complications with any type of surgery, it?s not usually advised unless your bunions are causing pain, or if it is starting to deform your other toes.
