A bunion, (medical term: hallux abductovalgus) is a condition resulting in boney prominence at the inside of the foot at the big toe joint. A bunion occurs when the big toe begins to deviate toward the second toe. The biggest misconception is that bunions occur from an overgrowth of bone. While that may be true in very few people, the bunion really represents a dislocation of the big toe joint as it bulges against the skin.
Bunions may be hereditary, as they often run in families. This suggests that people may inherit a faulty foot shape. In addition, footwear that does not fit properly may cause bunions. Bunions are made worse by tight, poorly-fitting, or too-small shoes. Bunions may also happen due to inflammatory conditions such as arthritis. Anyone can get bunions, but they are more common in women. People with flat feet are also more likely to get bunions due to the changes in the foot caused by bunions. There is also a condition called adolescent bunion, which tends to occur in 10-to-15-year old girls.
Most patients complain of pain directly on the bunion area, within the big toe joint, and/or on the bottom of the foot. The bunion may become irritated, red, warm, swollen and/or callused. The pain may be dull and mild or severe and sharp. The size of the bunion doesn?t necessarily result in more pain. Pain is often made worse by shoes, especially shoes that crowd the toes. While some bunions may result in significant pain, other bunions may not be painful at all.
Your doctor can identify a bunion by examining your foot. Watching your big toe as you move it up and down will help your doctor determine if your range of motion is limited. Your doctor will also look for redness or swelling. After the physical exam, an X-ray of your foot can help your doctor identify the cause of the bunion and rate its severity.
Non Surgical Treatment
The treatment of bunions should be individualized because the degree of deformity is not always consistent with the degree of pain. The most important first step in the treatment (and prevention) of bunions is to wear properly fitted shoes, with a low heel and adequate room in the toe area. Further treatment may include relative rest and icing to decrease pain around the MTP joint, medications to reduce inflammation and pain, stretching and strengthening exercises and shoe orthotics. If the above measures are not successful, surgery may be required.
One of the more popular proximal metatarsal osteotomies that is performed is called the Myerson/Ludloff procedure. This operation is performed for more advanced deformity. Screws are inserted into the metatarsal to hold the bone cut secure and speed up bone healing. Walking is permitted in a surgical shoe following surgery. The shoe is worn approximately 5 weeks.
