If you have bunions, taking care of them now can help you avoid more serious treatment later. A bunion is a bump that forms on the joint of the big toe when bone or tissue moves out of place and extends beyond the normal anatomy of the toe. Left untreated, bunions can cause debilitating pain and may require surgery to correct. Causes
The classic bunion, medically known as hallux abductovalgus or HAV, is a bump on the side of the great toe joint. This bump represents an actual deviation of the 1st metatarsal and often an overgrowth of bone on the metatarsal head. In addition, there is also deviation of the great toe toward the second toe. In severe cases, the great toe can either lie above or below the second toe. Shoes are often blamed for creating these problems. This, however, is inaccurate. It has been noted that primitive tribes where going barefoot is the norm will also develop bunions. Bunions develop from abnormal foot structure and mechanics (e.g. excessive pronation), which place an undue load on the 1st metatarsal. This leads to stretching of supporting soft tissue structures such as joint capsules and ligaments with the end result being gradual deviation of the 1st metatarsal. As the deformity increases, there is an abnormal pull of certain tendons, which leads to the drifting of the great toe toward the 2nd toe. At this stage, there is also adaptation of the joint itself that occurs.
Symptoms
Symptoms, which occur at the site of the bunion, may include pain or soreness, inflammation and redness, a burning sensation, possible numbness. Symptoms occur most often when wearing shoes that crowd the toes, such as shoes with a tight toe box or high heels. This may explain why women are more likely to have symptoms than men. In addition, spending long periods of time on your feet can aggravate the symptoms of bunions.
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
Patients should immediately cease using improperly fitted shoes. Footwear selection should have a wide and roomy toebox to accommodate the full width of the foot. If the problem is the over-pronation, the patient should be fitted with orthotics and can expect a slow recovery from pain over a period of months. Orthotics will not cause the physical deformity to regress, but will simply arrest any further progression and likely stop the pain. It is important to note however, that when bunions are severe and require surgery, the bunion can be corrected, but will develop again unless the root cause of over-pronation is corrected. If over-pronation is the root cause, orthotics will still be necessary.
Surgical Treatment
Surgery may be considered if your symptoms are severe and don't respond to non-surgical treatments. The type of surgery will depend on the level of deformity, the severity of your symptoms, your age, and any other associated medical conditions.
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.
