A bunion is enlargement of bone or tissue that develops at the joint that connects your big toe to your foot. The bones, muscles, ligaments and tendons of your feet normally are well-balanced to distribute your body's weight while standing, walking and running. When the joint, called the metatarsophalangeal joint, or MTP joint, experiences abnormal, prolonged stress in terms of weight distribution or squeezing of the toes within the shoe, the result can be the deformity called a bunion. Generally, a bunion develops when, as a response to prolonged stress, your big toe begins bending toward your foot's smaller toes and puts pressure on your MTP joint, forcing it to bulge outward (the term "bunion" comes from the Latin word for "enlargement"). There is no "standard" bunion, however, but rather a complex range of joint, bone and tendon abnormalities that can cause variation in each bunion's make-up.
Although they may develop on the fifth (little) toe, bunions usually occur at the base of the big toe. Bunions are often caused by incorrect foot mechanics. The foot may flatten too much, forcing the toe joint to move beyond normal range. In some cases, joint damage caused by arhritis or an injury produces a bunion. And some people are simply born ith extra bone near a toe joint. If you're at risk for developing a bunion, wearing high-heeled or poorly fitting shoes make the problem worse. As new bone grows, the joint enlarges. This stretches the joint's outer covering. Force created by the stretching pushes the big toe toward the smaller ones. Eventually, the inside tendons tighten, pulling the big toe farther out of alignment.
Many people with bunions 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-all contributing to chronic bunion pain.
When an x-ray of a bunion is taken, there is usually angulation between the first metatarsal bone and the bones of the big toe. There may also be angulation between the first and second metatarsal bones. These angular irregularities are the essence of most bunions. In general, surgery for bunions aims to correct such angular deformities.
Non Surgical Treatment
The treatment method your doctor chooses for you will be based on the severity of the bunion. Treatment can be simple and non-surgical or it can be complex, surgical, and costly. A bunion is permanent unless surgery is performed to remove it, but self-care can help to improve your symptoms. If you suspect that a bunion is developing, you should seek medical attention immediately. Here are the most common conservative treatment options. Changing your shoes. Adding custom orthotics to your shoes. Medication such as Tylenol for pain relief. Padding and taping to put your foot in its normal position. Applying ice or cold compresses to reduce swelling and pain. Keeping pressure off your affected toe, especially if there is swelling, redness, and pain. Before bed, separate the affected toe from the others with a foam-rubber pad and leave it there while you sleep.
If nonsurgical treatment fails, you may want to consider surgery. Many studies have found that 85 to 90 percent of patients who undergo bunion surgery are satisfied with the results. Reasons that you may benefit from bunion surgery commonly include severe foot pain that limits your everyday activities, including walking and wearing reasonable shoes. You may find it hard to walk more than a few blocks (even in athletic shoes) without significant pain. Chronic big toe inflammation and swelling that doesn't improve with rest or medications. Toe deformity-a drifting in of your big toe toward the small toes. Toe stiffness-inability to bend and straighten your toe. Failure to obtain pain relief from nonsteroidal anti-inflammatory drugs. Their effectiveness in controlling toe pain varies greatly from person to person. Failure to substantially improve with other treatments such as a change in shoes and anti-inflammatory medication. 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.
Shop for shoes that possess a removable liner, or insole, and stand on the liner after you have removed it from your shoe. This is an effective method to see if your shoe is wide enough in the forefoot to accommodate your bunion. If your bunion and forefoot are wider than the insole, your shoe will squeeze and constrict your bunion and create the symptoms that define this health problem. The insole should also be wide enough to fully accommodate your big toe when it points outward, away from your other toes.
