Bunion is the common term for a medical condition known as Hallux Valgus. Hallux Valgus is the tilting of the toe away from the mid-line of the body. It is usually characterized by a lump or bump that is red, swollen and/or painful on the inside of the foot in and around the big toe joint.
It is thought that the primary cause of bunions is a mechanical instability in the big toe joint. There are a number of different reasons as to why this may happen. Bunions tend to run in families so a person with a family history of bunions has an increased risk of developing them. Factors that are known to increase the risk of bunions include wearing improperly fitting shoes (particularly narrow and/or high-heeled shoes). Certain arthritic conditions and ligament disorders. Age (the incidence of bunions increases with age). Being flatfooted with feet that roll inwards (over pronation). Past injury (trauma) to the foot. Nerve conditions affecting the foot. Bunions most commonly affect women (approximately 90% of cases) and are less common in people who do not regularly wear shoes.
SymptomsA 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 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
The initial treatment of a bunion should be non-operative. Symptoms can often be greatly improved with simple non-operative interventions. Non-operative treatment may include properly fitted shoes, Properly fitting comfort shoes with a wide non-constrictive toe box, especially one that is made out of a soft material such as leather, can be quite helpful in reducing the irritation over the prominent bunion. In some instances, it is helpful to have a shoemaker stretch the inside aspect of the shoe. Jamming a foot with a bunion into a constrictive shoe will likely lead to the development of uncomfortable symptoms. Bunion pads, Medial bunion pads may also be helpful in decreasing the symptoms associated with the bunion. These pads can be obtained at many drugstores. Essentially, they serve to lessen the irritation over the medial prominence and, thereby, decrease the associated inflammation This should be combined with comfortable non-constrictive shoes. A toe spacer placed between the great toe and the second toe can help to reduce the bunion deformity and, thereby, decrease the stretch on the medial tissue and the irritation associated with the bunion. Toe spacers can be obtained at most drug stores or online. Soft shoe inserts. Over-the-counter accommodative orthotics may also help bunion symptoms. This product is particularly helpful if bunion symptoms include pain that is under the ball of the foot. Orthotics with a slight medial longitudinal arch may be helpful for patients that have associated flatfoot deformity. These can be purchased at many sports stores, outdoors stores, or pharmacies. Bunion splints have often been used to treat the symptoms associated with hallux valgus. These splints are typically worn at night in an effort to reduce the bunion deformity. There is no evidence to suggest that these splints decrease the rate at which bunion deformities occur. There is also no evidence that clearly supports their effectiveness. However, some patients report good relief with the use of these splints.
Bunion surgery can be performed under local or general anaesthetic. The operation usually takes between half an hour to an hour. There are several types of bunionectomies. Some involve removal and realignment of the bones in your foot. Mild bunion problems can sometimes be resolved using soft tissue release or tightening. For some very severe cases bones of the big toe are fused or the bunion is cut out along with some of the bone at the base of the toe. Be sure and discuss which type of operation you will have with your surgeon. With any type of bunionectomy your surgeon will make one or more incisions (cuts) near your big toe. They will use instruments to trim the bones and remove the bunion. Wire, screws or plates may also be used to hold the new joint in place.
