Overview
A bunion (a.k.a Hallux Valgus) is a common foot condition associated with a prominent bump on the inside of the forefoot (see Figure 1). The word bunion? comes from the Greek root for the word turnip. Bunions can lead to discomfort over the prominence, especially if patients wear tight fitting shoes. It is common for bunions to run in family? and gradually increase over time. The vast majority of bunions can be managed successfully with basic non-operative treatment. Surgery is reserved for patients who have persistent symptoms in spite of appropriate non-operative treatment.
Causes
You are usually born with a foot type that leads to bunion formation. Flat feet with increased flexibility are most likely to form bunions. Abnormal mechanics increase the bunion formation over time. Other causes of bunions include osteoarthritis, gout, rheumatoid arthritis, trauma, and neurovascular disease.
Symptoms
The symptoms of bunions include irritated skin around the bunion, pain when walking, joint redness and pain, and possible shift of the big toe toward the other toes. Blisters may form more easily around the site of the bunion as well. Having bunions can also make it more difficult to find shoes that fit properly; bunions may force a person to have to buy a larger size shoe to accommodate the width the bunion creates. When bunion deformity becomes severe enough, the foot can hurt in different places even without the constriction of shoes because it then becomes a mechanical function problem of the forefoot.
Diagnosis
When an x-ray of a bunion is taken, there is usually angulation between the first metatarsal bone and the bones of the big toe. There may also be angulation between the first and second metatarsal bones. These angular irregularities are the essence of most bunions. In general, surgery for bunions aims to correct such angular deformities.
Non Surgical Treatment
A hinged flexible bunion splint, can relieve pain by providing corrective arch support and releasing tension away from the inflamed joint. Change shoes! Avoid flip flops, high-heels and shoes with pointed, narrow toe-boxes. Medicine will not prevent or cure bunions. However, the use of over the counter anti- inflammatory medications can help. Bunion splints, pads and arch supports can help redistribute weight and move pressure away from the big toe.
Surgical Treatment
If these methods fail, then surgery may be suggested. Basically, bunion surgery is performed to improve function or to prevent pain from occurring. When surgery is delayed in a symptomatic foot, greater amounts of arthritis can develop and the more complicated surgery can become. Surgery is performed to improve alignment and function to the big toe joint. The large bump is removed and, sometimes, a cut is made into the bone, to move it to a more normal position. Screws, pins and wires can be used beneath the skin, to improve healing and results. Healing can range from 3-12 weeks, depending on the procedure.
Prevention
Make better shoe choices. If you?re a woman, avoid high-heeled footwear whenever possible (at the very least, choose shoes with heels lower than two inches), and make sure all your footwear has a wide, deep toe box. Whether man or woman, if you?re trying on shoes and your toes feel ?squished? or crowded by a particular shoe, reject that style and try another, or go for a larger size. You don?t need to invite trouble. In general, shoes that come to a point at the toe are bad news, as they tend to push the toes together into an overlapping pattern. Shoes with rocker soles will unload pressure on the bunion area. Examine your feet regularly. Note any redness, swelling or discoloration. Flex your toes and check for any stiffness. If there is any, think back to what you?ve worn or done in the past few days. If the condition persists more than a few days, or worsens, a visit to the podiatric physician is in order.
