Overview

The big toe of the foot is called the hallux. If the big toe starts to deviate inward in the direction of the baby toe, the condition is called hallux valgus. As the big toe drifts over into valgus, a bump starts to develop on the inside of the big toe over the metatarsal bone. This bone prominence on the inner edge for the metatarsal is referred to as a bunion.

Causes
Essentially, bunions are caused by a disruption of the normal interworking of the bones, muscles, ligaments and tendons that comprise your feet, often from wearing shoes that squeeze the toes or place too much weight-bearing stress on them. However, it should be pointed out that other causes or factors in the development of bunions can include flat feet or low arches in the feet, some forms of arthritis, problems with foot mechanics, foot injuries and neuromuscular disorders such as cerebral palsy. Arthritis in the MTP joint, for example, can degrade the cartilage that protects it, and other problems may cause ligaments to become loose. Pronation, walking in a way that your foot rolls inwards, increases your risk for developing bunions.
SymptomsBunions are readily apparent, you can see the prominence at the base of the big toe or side of the foot. However, to fully evaluate your condition, the Podiatrist may take x-rays to determine the degree of the deformity and assess the changes that have occurred. Because bunions are progressive, they don't go away, and will usually get worse over time. But not all cases are alike, some bunions progress more rapidly than others. There is no clear-cut way to predict how fast a bunion will get worse. The severity of the bunion and the symptoms you have will help determine what treatment is recommended for you.

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
Wide shoes with plenty of space for the toes are the first place to start. Along these lines, a shoe can be focally stretched directly over the painful bunion using a device known as a ?ball and ring? shoe stretcher. Additionally, numerous commercial bunion braces and splints are available to help keep the big toe in better alignment.


Surgical Treatment
Bunion surgery is both an art and a science, and it should always be performed by a healthcare professional who understands the multifaceted mechanics of your first MTP and its surrounding structures. Bunion surgery involves more than just removing the bump at the base of your big toe, and it is best followed up with supportive therapies to prevent a recurrence of your health problem.
