A bunion is a bone deformity caused by an enlargement of the joint at the base and side of the big toe (metatarsophalangeal joint). Bunions form when the toe (the hallux) and the 1st metatarsal (the bone behind the big toe) move out of place. The enlargement and its protuberance cause friction and pressure as they rub against footwear. The growing enlargement then causes irritation or inflammation. In some cases, the big toe moves toward the second toe and rotates or twists, which is known as Hallus Abducto Valgus. Bunions can also lead to other , such as hammertoes.
Many people with bunions suffer from discomfort and pain from the constant irritation, rubbing, and friction of the enlargement against shoes. The skin over the toe becomes red and tender. Because this joint flexes with every step, the bigger the bunion gets, the more it hurts to walk. Over time, or arthritis may set in, the skin on the bottom of the foot may become thicker, and everyday walking may become difficult—all contributing to chronic pain.
Wearing shoes that are too tight is the leading cause of bunions. Bunions are not hereditary, but they do tend to run in families, usually because of Online Blackjack a faulty foot structure. Foot injuries, neuromuscular problems,flat feet, and can contribute to their formation. It is estimated that bunions occur in 33 percent of the population in Western countries.
Treatment for Bunions
Because they are bone deformities, bunions do not resolve by themselves. The goal for bunion treatment is twofold: first, to relieve the pressure and pain cause by irritations, and second to stop any progressive growth of the enlargement. Commonly used methods for reducing pressure and pain caused by bunions include:
- The use of protective padding to eliminate the friction against shoes and help alleviate inflammation and skin problems.
- Removal of corns and callouses on the foot.
- Changing to carefully-fitted footwear designed to accommodate the bunion and not contribute toward its growth.
- Orthotic devices (custom-made inserts)—to help stabilize the joint and place the foot in the correct position for walking and standing.
- Exercises to maintain joint mobility and prevent stiffness or arthritis.
Depending on the size of the enlargement, misalignment of the toe, and pain experienced, conservative treatments may not be adequate to prevent progressive damage from bunions. In these cases, bunion surgery, known as a bunionectomy, may be advised to remove the bunion and realign the toe.
