Bunion also known as (hallux abducto-valgus) is a bony deformity caused by an enlargement of the joint at the base and side of the big toe (metatarsophalangeal joint). Bunion forms when the big toe moves out of place. The enlargement and its protuberance cause friction and pressure as they rub against footwear. Over time, the movement of the big toe angles in toward the other toes (known as Hallux Abductus). The growing enlargement or protuberance then causes more irritation or inflammation. In some cases, the big toe moves toward the second toe and rotates or twists, which is known as Hallux Abducto-Valgus. Bunions can also lead to other toe deformities, such as hammertoes and deviation of other toes as well.
Many people with bunion 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, bursitis or arthritis may set in, the skin on the bottom of the foot may become thicker, and everyday walking may become difficult and contributing to chronic pain.
Bunion Treatment (Conservative):
Bunions are bony deformities, and 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, 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 / wider 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
- Topical pain relieving gel
- X-ray: May be needed to evaluate for possible arthritis to the big toe joint.
Bunion Treatment (Surgical):
Depending on the size of the bunion, malalignment of the toe and amount of pain experienced, conservative treatments may not be adequate to prevent progressive damage from bunions. In these cases, bunion surgery may be needed. Surgical bunion treatment is known as a bunionectomy, may be advised to remove the bunion and realign the toe.
