Overview

Bunion deformities are often part of a more generalized problem related to improper foot motion as you walk. The name for this is "pronation". Wearing orthotics can slow the progress of a bunion deformity. There are presently over 25 types of bunion procedures performed today. The choice of procedure is based on many factors including age, medical history, physical exam, and x-ray evaluation.

Causes
No one single cause has been proven. There are a number of causes, and though shoes can exacerbate the problem, bunions do occur in societies that don?t wear them. We walk on the same type of ground all the time, whereas the human foot was actually designed to adapt to varying terrains. In a sense, a bunion is a type of repetitive strain injury. And like repetitive strain injury, some people are more prone to it than others. One theory, though it remains unproven, is that bunions are caused by one or both of the following. Because the foot wasn?t designed to constantly walk on a level surface, the ball of the big toe is slightly lower than the ball of the rest of your foot. When your foot meets the ground, the ball of the big toe is pushed up, and the big toe joint can?t bend as well as it was designed to. In order for the big toe joint to bend fully as you walk, your foot rolls slightly over to the side (this is also why people with hallux valgus often get hard skin). Also, if your midtarsal joint tends to move from side to side more than it does up and down, the arch in your foot collapses as your foot rolls in. This also makes you more prone to developing bunions. Such problems can be exacerbated by tight footwear. Slip-on shoes can make matters worse. Because they have to be tighter to stay on your feet, you automatically have less room for your toes. And with nothing to hold your foot in place, your toes often slide to the end where they?re exposed to lots of pressure. Likewise, high heels throw more weight onto the ball of the foot, putting your toes under further pressure. If you haven?t got a bunion by adulthood and you later develop one, there could be some underlying arthritis.
SymptomsThe signs and symptoms of a bunion include a bulging bump on the outside of the base of your big toe, swelling, redness or soreness around your big toe joint, Thickening of the skin at the base of your big toe, Corns or calluses, these often develop where the first and second toes overlap, persistent or intermittent pain, restricted movement of your big toe. Although bunions often require no medical treatment, see your doctor or a doctor who specializes in treating foot disorders (podiatrist or orthopedic foot specialist) if you have persistent big toe or foot pain, a visible bump on your big toe joint, decreased movement of your big toe or foot, difficulty finding shoes that fit properly because of a bunion.

Diagnosis
Your doctor will be able to diagnose a bunion by asking about your symptoms and examining your feet. You may also have blood tests to rule out any other medical conditions, such as rheumatoid arthritis or gout, although this is rare. Your doctor may refer you to a podiatrist or chiropodist (healthcare professionals who specialise in conditions that affect the feet).

Non Surgical Treatment
You can buy orthotics over the counter from pharmacies, or they can be custom-made by a podiatrist to fit your feet. Whether you need to buy an over-the-counter orthotic or have one specially made will depend on your individual circumstances and the severity of your bunion. You can also use special bunion splints, worn over the top of your foot and your big toe to help straighten its alignment. Splints are available for both daytime and night-time use. However, there's little evidence that splints are effective. Toe spacers are also available, which can help reduce the pain caused by bunions. However, toe spacers or orthotics may be of limited use because they often compete with the bunion for the already limited space in the shoe. If your toe joint is painful and swollen, applying an ice pack to the affected area several times a day can help to relieve the pain and inflammation. Never apply ice directly to your skin. Wrap it in a cloth or tea towel. A bag of frozen vegetables makes a good ice pack. It's recommended that you wear flat or low-heeled, wide-fitting shoes if you have a bunion. Shoes made from soft leather are ideal because they'll relieve any pressure on the bunion. Avoid narrow or slip-on shoes. High heels can also make your bunion worse by putting excessive pressure on your toes.


Surgical Treatment
When the pain of a bunion interferes with daily activities, and conservative treatment has been completed it's time to discuss surgical options. Foot Mechanics has excellent relationships with many Orthopaedic Surgeons, who are the specialists who perform bunion surgery. Because bunions are caused by faulty foot mechanics surgery can improve the look of your feet by removing the ?bump? but if the underlying mechanics are not addressed then the bunion is likely to return. For this reason orthotics are used post-surgery to prevent the return of bunions.

Prevention
There are some steps that may help prevent, or at least slow, the progression of bunions. Avoid shoes with a narrow toe box. If your foot flattens excessively, make sure you wear supportive shoes, and if necessary, get custom orthotics from your podiatrist. See your podiatrist at the first signs or symptoms of a bunion deformity, as early treatment may stop or slow its progression.
