A bunion is an unnatural, bony hump that forms at the base of the big toe where it attaches to the foot. Often, the big toe deviates toward the other toes. When this occurs, the base of the big toe pushes outward on the first metatarsal bone, which is the bone directly behind the big toe, forming a bunion. If this happens on the little toe and fifth metatarsal, it's called a bunionette. Because a bunion occurs at a joint, where the toe bends in normal walking, your entire body weight rests on the bunion at each step. Bunions can be extremely painful. They're also vulnerable to excess pressure and friction from shoes and can lead to the development of calluses.
Bunions most commonly affect women. Some studies report that bunions occur nearly 10 times more frequently in women. It has been suggested that tight-fitting shoes, especially high-heel and narrow-toed shoes, might increase the risk for bunion formation. Bunions are reported to be more prevalent in people who wear shoes than in barefoot people. While the precise causes are not known, there also seems to be inherited (genetic) factors that predispose to the development of bunions, especially when they occur in younger individuals. Other risk factors for the development of bunions include abnormal formation of the bones of the foot at birth (congenital), nerve conditions that affect the foot, rheumatoid arthritis, and injury to the foot. Bunions are common in ballet dancers.
Signs and symptoms of a bunion include the base of the big toe is swollen and sticks out. The big toe is often bent towards the other toes, and sometimes the second toe is pushed to overlap the third toe. Skin around the big toe joint is red and sore. Thickened skin at the base of the big toe. Pain in the big toe or foot. Wearing shoes is painful. Pain or difficulty when walking.
Your doctor is very likely to be able to diagnose your bunion simply by examining your foot. Even before that, he or she will probably ask about your family and personal medical history and evaluate the types of shoes you wear. You'll be asked about your symptoms, when they started and when they occur. You may also be asked to flex your toe so that your doctor can get an idea of your range of motion. He or she may order x-rays in order to determine the extent of your deformity.
Non Surgical Treatment
Most bunions can be treated without surgery. The first step for treating bunions is to ensure that your shoes fit correctly. Often good footwear is all that is needed to alleviate the problem. Shoes that are wide enough to avoid pressure on the bunion are the obvious first step. Look for shoes with wide insteps and broad toes and definitely no high heels. Sometimes, you can get your existing shoes stretched out by a shoe repairer. Seek advice from a podiatrist. Pads and toe inserts. Protective bunion pads may help to cushion the joint and reduce pain. Toe inserts are available that splint the toes straight. It may be recommended that you wear some orthotics to improve your foot position when walking. Medicines. Some people find anti-inflammatory medicines, such as ibuprofen or aspirin, or paracetamol help ease the pain of their bunions.
If surgery is required to correct a symptomatic bunion, there are several procedures that may be used, depending on the size and degree of the deformity. For mild deformities, a simple shaving of the bony prominence may suffice. At the same time, the tissues on the inner, or medial, side of the joint are tightened to hold the great toe in a more neutral alignment. When only the bone is shaved, this procedure is commonly referred to as a ?Silver? procedure. When the bone is shaved and the soft tissues tightened, this is called a ?modified McBride? procedure.
Choosing footwear that fits correctly, especially low heeled shoes with plenty of space for the toes, is one of the main ways that bunions can be prevented. Always stand when trying on shoes to ensure they still fit comfortably when the foot expands under your body weight. Try shoes on both feet, and select the size appropriate for your larger foot. Use an extra insole if one shoe is looser than the other. Do not cramp the larger foot. People prone to flat-footedness should consider the use of arch supports, orthotic shoe inserts or special orthotic shoes to prevent or delay the development of bunions.
