Overview
The original definition of a bunion was a bursa (a fluid-filled sac) on the side of the foot near the base of the big toe. The bursa was caused by a chronic friction of the patient's first metatarsal bone (the bone to which the big toe attaches) and the shoe. Few people go by this definition any longer. Today most people consider a bunion to be the enlarged bone on the side of the foot that typically caused the bursa. Along with this bump, there is usually an associated mis-alignment of the big toe, with it leaning in towards the second toe. In medical jargon, the term for a bunion is "Hallux Abducto Valgus," or "HAV" for short. Though the condition is really slightly different, it may also be known as "Hallux Valgus." Bunions are usually a progressive problem, and can make it difficult to find shoes that fit. The condition is often quite uncomfortable, not only because of the pressure the shoes exert on the bump, but because of the other factors associated with bunions, which we shall discuss shortly.

Causes
With prolonged wearing of constraining footwear your toes will adapt to the new position and lead to the deformity we know as a foot bunion. Footwear is not the only cause of a bunion. Injuries to the foot can also be a factor in developing a bunion. Poor foot arch control leading to flat feet or foot overpronation does make you biomechanically susceptible to foot bunions. A family history of bunions also increases your likelihood of developing bunions. Many people who have a bunion have a combination of factors that makes them susceptible to having this condition. For example, if you are a women over the age of forty with a family history of bunions, and often wear high-heeled shoes, you would be considered highly likely to develop a bunion.
Symptoms
The major symptom of bunions is a hard bump on the outside edge of the foot or at the base of the big toe. Redness, pain and swelling surrounding or at the MTP joint can also occur.
Diagnosis
Before examining your foot, the doctor will ask you about the types of shoes you wear and how often you wear them. He or she also will ask if anyone else in your family has had bunions or if you have had any previous injury to the foot. In most cases, your doctor can diagnose a bunion just by examining your foot. During this exam, you will be asked to move your big toe up and down to see if you can move it as much as you should be able to. The doctor also will look for signs of redness and swelling and ask if the area is painful. Your doctor may want to order X-rays of the foot to check for other causes of pain, to determine whether there is significant arthritis and to see if the bones are aligned properly.
Non Surgical Treatment
Early treatment of bunions is centered on providing symptomatic relief. Switching to a shoe with a rounder, deeper toe box and made of a softer more pliable leather will often provide immediate relief. The use of pads and cushions to reduce the pressure over the bone can also be helpful for mild bunion deformities. Functional foot orthotics, by controlling abnormal pronation, reduces the deforming forces leading to bunions in the first place. These may help reduce pain in mild bunion deformities and slow the progression of the deformity. When these conservative measures fail to provided adequate relief, surgical correction is indicated.
Surgical Treatment
For very severe bunion deformities where there is considerable angulation between the first and second metatarsals an osteotomy of the metatarsal may not be sufficient and for these patients, the joint between the first metatarsal and the cuneiform bone is fused with screws, called the Lapidus procedure. This realigns the metatarsal completely and stabilizes the bone, preventing mobility and recurrent deformity.
Prevention
Wear insoles and well-fitting shoes to help slow down the progression of bunions and alleviate discomfort. Cushioning can also help alleviate discomfort. Consider wearing shoes with a wide toe box so they don't crowd your toes. Children can also develop bunions and should wear properly fitting shoes as their feet are still developing.
