Bunions

foot-bunionBunions are bone deformities caused by an enlargement of the joint at the base and side of the big toes (metatarsophalangeal joint). Bunions form when the toe moves out of place. The enlargement and its protuberance cause irritation and pressure as they rub against shoe wear. Over time, the big toe moves toward the other toes, commonly cause underlapping or overlapping the second toe. The growing enlargement or protuberance then causes more irritation or inflammation. Also, bunions can lead to other toe deformities, such as hammertoe.

Wearing shoes that are too tight is the leading cause of bunions. Bunions are usually not hereditary, but they do tend to run in families, commonly because of a faulty foot structure. Foot injuries, neuromuscular problems, flat feet, and pronated feet can contribute to their formation.

Bunion suffers complain of 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, bursitis 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.

Conservative Treatments 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 caused by irritations, and second to stop any progressive growth of the enlargement. Commonly used methods for reducing pressure and pain caused by bunions include:

  • Protective padding, often made from felt material, to eliminate the friction against shoes and help alleviate inflammation and skin problems.
  • Removal of corns and calluses on the foot.
  • Changing to carefully fitted footwear designed to accommodate the bunion and not contribute toward its growth.
  • Orthotic devices—both over-the-counter and custom made—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.
  • Splints for nighttime wear to help the toes and joint align properly. This is often recommended for adolescents with bunions, because their bone development may still be adaptable.

Surgical Treatment for Bunions

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.
