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. Causes
Bunions have a number of causes, primarily genetics and bad choices in footwear. We inherit traits like flat feet, abnormal bone structure, and loose ligaments and tendons from our parents. When our feet are weakened by these traits and we stuff them into high heels or shoes which don?t support our feet correctly, the repeated stress on the front of the foot may contribute to the formation of a bunion. Other contributing factors are jobs that demand a lot of time standing, obesity, and sudden hormonal changes and weight gain, as in pregnancy. Unfortunately, bunions can lead to many other foot conditions as well. The joint behind the big toe carries much of your body weight and when the bunion makes it sore, you shift your weight onto other areas of the foot. That?s why we frequently see crossover toes, overlapping toes, hammer toes, corns, calluses, and ingrown toenails accompanying bunions. As pain in your foot increases, you?ll also reduce your activity, becoming more sedentary, which has its own quality-of-life issues.
Symptoms
Pain in the toe joint and surrounding area. Painful to touch or press, and when walking. Growth of a bony lump (exostosis) at the side of the big toe joint. Irritated skin around the bunion. Redness. Thickening of overlying skin. Blisters may form more easily. Deformed bones, joints and ligaments as the big toe shifts towards the other toes. As the big toe shifts, its base becomes more prominent, forming the bunion. Eventually the big toe is forced to lie over, or more commonly under, the second toe. The second toe of patients who have bunions commonly forms a hammer toe. Trouble with shoes. It is difficult to find shoes that fit properly. Bunions may force you to buy a larger size shoe to accommodate the width the bunion creates. Eventually it hurts to wear any shoe, or even walk barefoot.
Diagnosis
Your family doctor or chiropodist /podiatrist can identify a bunion simply by examining your foot. During the exam, your big toe will be moved up and down to determine if your range of motion is limited. You will be examined for signs of redness or swelling and be questioned about your history of pain. A foot x-ray can show an abnormal angle between the big toe and the foot. In some cases, arthritis may also be seen. A X-ray of your foot may help identify the cause of the bunion and rate its severity.
Non Surgical Treatment
Several things can be done to help relive the pain of bunions. These won't make the bunion go away, but they can make the foot more comfortable. Wearing different shoes. Shoes with a wide toe box rather than a pointed one will help. Shoes with lower heels will also help. (High heels throw more of the body's weight on the front part of the foot where the toe joints are.) Padding. Pads placed over the bunion may help reduce the pain. These are available from a drug store or may be available from a foot and ankle surgeon. Avoiding activities that make the pain worse. This includes standing for a long time or other activities that make the bunion sore. Non-steroidal anti-inflammatory drugs. These include aspirin or ibuprofen. They relieve pain and swelling. Applying an ice pack to reduce swelling and pain. Corticosteroid injections. These are not often used in bunion treatment. Injecting corticosteroids sometimes helps if the bursa is inflamed. (Bursa is a fluid-filled sac within a joint to cushion the bones). Orthotic devices. These are devices placed inside a shoe that shift the positioning of the foot. Orthotics help compensate for structural issues that cause foot problems.
Surgical Treatment
The most significant portion of the bunion surgery is re-aligning the bones. This is performed though bone cuts or a fusion involving the first metatarsal. The severity of the bunion determines where the bone will be cut or fused. Mild or moderate bunions can be corrected close to the big toe joint. Moderate or large bunions often require that the bone work be performed further away from the big toe joint to swing the bone in the proper position.
Prevention
If these exercises cause pain, don't overdo them. Go as far as you can without causing pain that persists. This first exercise should not cause pain, but is great for stimulating blood and lymphatic circulation. Do it as often as you can every day. Only do this exercise after confirming it is OK with your doctor. Lie on your back and lift up your legs above you. Wiggle your toes and feet. Eventually you may be able to rapidly shake your feet for a minute at a time. Use your fingers to pull your big toe into proper alignment. Stretch your big toe and the rest of your toes. Curl them under for 10 seconds, then relax and let them point straight ahead for 10 seconds. Repeat several times. Do this at least once a day, and preferably several times. Flex your toes by pressing them against the floor or a wall until they are bent back. Hold them for 10 seconds, then release. Repeat several times. Grip with your toes. Practice picking up an article of clothing with your toes, dropping it, and then picking it up again. Warm water. Soak your feet for 20 minutes in a bowl of warm water. Try doing the foot exercises while soaking, and also relax and rest your feet. Epsom salts. Add it to your warm foot bath soak.
