Overview

A bunion is a firm, painful bump that forms over a bony bulge at the base of the big toe. In most cases, the big toe joint also is enlarged and has degenerative arthritis. The toe also may be pushed toward the second toe (hallux valgus). Bunions tend to be inherited, but they also are common in the following groups. Women who wear high heels. People who wear shoes that are too narrow or too pointed. People with flatfeet. All of these situations force the big toe to drift toward the little toes, and this can cause bunions to form.

Causes
Shoes with narrow toes can trigger a bunion, but they?re not the underlying cause. Bunions run in families, because foot type (shape and structure) is hereditary, and some types are more prone to bunions than others. Low arches, flat feet, and loose joints and tendons all increase the risk. The shape of the metatarsal head (the top of the first metatarsal bone) also makes a difference: if it?s too round, the joint is less stable and more likely to deform when squeezed into shoes with narrow toes.
SymptomsThe pain from a bunion is felt around the MTP joint of the big toe. People with bunions often complain of pain when they when they stand or walk for long periods of time. High heeled shoes or shoes with a small toe area can make bunions feel and look worse. As a result of the deformity the big toe can lose some of its range of motion or become stiff. Sometimes both feet are affected.

Diagnosis
Your family doctor or chiropodist /podiatrist can identify a bunion simply by examining your foot. During the exam, your big toe will be moved up and down to determine if your range of motion is limited. You will be examined for signs of redness or swelling and be questioned about your history of pain. A foot x-ray can show an abnormal angle between the big toe and the foot. In some cases, arthritis may also be seen. A X-ray of your foot may help 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 are many different surgical procedures that can be performed. The decision to perform one type of surgery or another is based upon the extent and magnitude of the bunion deformity, the presence of arthritis in the big toe joint, and the space between the first and second metatarsals, which is called the intermetatarsal angle. It is very rare that a bunion can be treated by simply shaving down the bump of the bone. Invariably, the deformity will recur and both the bunion and the hallux valgus will return. Therefore, the shaving of the bunion, called an exostectomy, is performed in conjunction with a cut of the first metatarsal bone (which is called an osteotomy).

Prevention
If these exercises cause pain, don't overdo them. Go as far as you can without causing pain that persists. This first exercise should not cause pain, but is great for stimulating blood and lymphatic circulation. Do it as often as you can every day. Only do this exercise after confirming it is OK with your doctor. Lie on your back and lift up your legs above you. Wiggle your toes and feet. Eventually you may be able to rapidly shake your feet for a minute at a time. Use your fingers to pull your big toe into proper alignment. Stretch your big toe and the rest of your toes. Curl them under for 10 seconds, then relax and let them point straight ahead for 10 seconds. Repeat several times. Do this at least once a day, and preferably several times. Flex your toes by pressing them against the floor or a wall until they are bent back. Hold them for 10 seconds, then release. Repeat several times. Grip with your toes. Practice picking up an article of clothing with your toes, dropping it, and then picking it up again. Warm water. Soak your feet for 20 minutes in a bowl of warm water. Try doing the foot exercises while soaking, and also relax and rest your feet. Epsom salts. Add it to your warm foot bath soak.
