Hallux abductovalgus (HAV) or bunion, is a commonly seen deformity of the first metatarsophalangeal joint (MPJ) in which the hallux is abducted and everted, frequently overriding the second toe. Although the terms HAV and bunion are often used synonymously (as is done in this paper), it should be noted that a bunion actually refers to the callus and inflamed adventitious bursa overlying the HAV deformity. Even though bunions have been described in the medical literature for several hundred years (the word bunion is believed to be derived from the Latin, bunio, meaning turnip), there continues to be much controversy concerning its etiology. This is most likely because the development of HAV is multifactorial, stemming from a variety of structural and functional aberrancies.
Hereditary and shoe gear are probably the most likely causes. Tight pointy shoes (and high heels) may promote the formation of a bunion. A bunion may develop rapidly or develop slowly over time. Some people have bunions in their teens while others only develop a bunion later in life. Bunions come in a variety of sizes - from small to severe. In some cases, the big toe may push against the second toe, and may result in pain and a hammer toe, or progress onto a severe disfiguring foot deformity. Depending on your overall health, symptoms and severity of the bunion, the condition may be treated conservatively and/or with surgery.
A bulging bump on the outside of the base of your big toe. Swelling, redness or soreness around your big toe joint aggravated by footwear. Red, calloused skin along the inside edge of the big toe. Corns or calluses under the ball of the foot or where the first and second toes overlap. Persistent or intermittent pain. Restricted movement of your big toe.
Your doctor is very likely to be able to diagnose your bunion simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate the types of shoes you wear. You'll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to determine the extent of your deformity.
Non Surgical Treatment
If abnormal pronation is identified and corrected early, the formation of a bunion can be prevented. However, if the bunion has already developed and cannot be tolerated by the patient, surgery is necessary. Amputation of the big toe ceased to be a treatment for bunions many generations ago, but only in the past few years have surgical procedures been developed to incorporate the realignment of the bone with the correction of the abnormal motion that led to deformity.
The most significant portion of the bunion surgery is re-aligning the bones. This is performed though bone cuts or a fusion involving the first metatarsal. The severity of the bunion determines where the bone will be cut or fused. Mild or moderate bunions can be corrected close to the big toe joint. Moderate or large bunions often require that the bone work be performed further away from the big toe joint to swing the bone in the proper position.
The best way to reduce your chances of developing a bunion is to wear shoes that fit properly. Any shoe that is too tight or too high will force your toes together and may cause the condition to develop. Shoes need to be wide enough, so they aren't rubbing against the joint, and preferably made of leather. Avoid shoes with a lot elaborate stitching at the front, as this can also cause irritation. Heels should be no more than three to four inches and you should only wear them occasionally. Court shoes should seldomly be worn, as they do not give the foot any support. Be honest with yourself, you know if your shoes aren't fitting you comfortably. Do something about it, or you will suffer for your vanity.
