Overview
A bunion (hallux abducto valgus) is a bony lump or enlargement that forms in the joint (metatarsal phalangeal joint) at the base of the big toe. The big toe points toward the other toes (lateral deviation) as the bunion progresses. The joint and surrounding tissue becomes inflamed and painful. Occasionally bunions can also form at the joint at the base of the smallest (fifth) toe. They are called a tailor's bunion or bunionette. Bunions can be accompanied by bursitis (inflammation of a small fluid-filled sac adjacent to the joint). With an advanced bunion the big toe may be so deformed that it has to lie over or under the second toe. In this situation it hurts to walk or wear any kind of shoe. About one in three people in most Western countries will get a bunion. They are about ten times more common in women than in men. Older people are more often affected than younger people, although bunions do occur in children with misaligned feet. Bunions should not be confused with gout or arthritis, which can also cause inflammation, deformity and pain around the toes and feet.
Causes
Bunions are more common in women than men. The problem can run in families. People born with abnormal bones in their feet are more likely to form a bunion. Wearing narrow-toed, high-heeled shoes may lead to the development of a bunion. The condition may become painful as the bump gets worse. Extra bone and a fluid-filled sac grow at the base of the big toe.
Symptoms
Pain or soreness. Inflamattion and redness. A burning sensation. Numbness on the side of the great toe. Other conditions which may occur secondary to bunions include calluses on the big toe, sore between the toes, ingrown toenails, and stiffness of the joint where the great toe attaches to the foot.
Diagnosis
Clinical findings are usually specific. Acute circumferential intense pain, warmth, swelling, and redness suggest gouty arthritis (see Gout) or infectious arthritis (see Acute Infectious Arthritis), sometimes mandating examination of synovial fluid. If multiple joints are affected, gout or another systemic rheumatic disease should be considered. If clinical diagnosis of osteoarthritic synovitis is equivocal, x-rays are taken. Suggestive findings include joint space narrowing and bony spurs extending from the metatarsal head or sometimes from the base of the proximal phalanx. Periarticular erosions (Martel sign) seen on imaging studies suggest gout.
Non Surgical Treatment
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 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 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
As you explore bunion surgery, be aware that so-called "simple" or "minimal" surgical procedures are often inadequate "quick fixes" that can do more harm than good. And beware of unrealistic claims that surgery can give you a "perfect" foot. The goal of surgery is to relieve as much pain, and correct as much deformity as is realistically possible. It is not meant to be cosmetic. There are several techniques available, often as daycare (no in-patient stay), using ankle block local anaesthetic alone or combined with sedation or full general anaesthesia. Most of the recovery occurs over 6-8 weeks, but full recovery is often longer and can include persistent swelling and stiffness. The surgeon may take one or more of the following steps in order to bring the big toe back to the correct position: (a) shift the soft tissue (ligaments and tendons) around the joint and reset the metatarsal bone (osteotomy), remove the bony bump and other excess bone or (b) remove the joint and connect (fuse) the bones on the two side of the joint (fusion). These are just a few examples of the many different procedures available and your treating surgeon can help you decide the best option for you.
Prevention
To minimize the chance of developing bunions, never force your feet into shoes that don?t fit. Choose a shoe that conforms to the shape of your foot. Opt for shoes with wider insteps, broad toes, and soft soles. Shoes that are short, tight, or sharply pointed should be avoided.
