What Causes Bunions?

Overview
Bunions are one of the most common forefoot deformities. A displacement of the bone under the 1st toe occurs. This causes the big toe to move towards the smaller toes. This shifting of the bones causes a bony prominence on the side of the patients foot (the bunion joint). Over a period of time the big toe may come to rest under (occasionally over) the 2nd toe.

Causes
Bunions develop when excess pressure is placed on the tendons and joints of the foot. As a result, the joints can become deformed and unstable. After years of pressure, the MTP joint suffers, leading to abnormal movement and bunions. Bunions are symptomatic of poor foot development (which can be genetic), walking habits, shoes, foot type and other reasons. Women often develop bunions as a result of tight shoes that squeeze the toes together. Bunions can also result from foot injuries, congenital deformities and neuromuscular disorders. Flat foot and low arch problems are often precursors to bunions, as are problems with serious arthritis or inflammatory joint disease. An overlap of the first and second toes often causes irritation and corns and can eventually lead to bunions. Poor motion of the big toe can also be a factor.

Symptoms
symptoms and problems caused by bunions include pain. You may then have difficulty walking due to pain. Inflammation and swelling at the base of the toe. This sometimes becomes infected. The foot may become so wide that it can be difficult to find wide enough shoes. You may get arthritis in the big toe. The second toe can become deformed. In severe cases, the big toe can push your second toe up out of place.

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
Wearing the right shoes, using shoe inserts (orthoses) and padding, and taking painkillers can all help to ease your symptoms of a bunion. However, these treatments can?t cure a bunion or stop it getting worse. If you have severe pain or discomfort from a bunion, you may be advised to have an operation to correct it. One of the most important things you can do is to wear the right footwear. You should try to wear flat, wide-fitting shoes with laces or an adjustable strap that fits you properly. You may also want to place a bunion pad over your bunion to give it some protection from the pressure of your shoes. You can usually buy these pads from a pharmacy, or get them from your podiatrist or chiropodist. He or she may also recommend a shoe insert, which can be moulded specifically to your foot. Shoe inserts aim to reduce the pain of your bunion by improving how you walk. You can take over-the-counter painkillers, such as paracetamol or ibuprofen, to help relieve the pain and inflammation of your bunion. Always follow the instructions in the patient information leaflet that comes with your medicine. Medicines give temporary relief but they won?t be able to cure your bunion or prevent it from getting worse. If you have a bunion as a result of underlying arthritis, your doctor may prescribe specific medicines to treat this.

Surgical Treatment
If the bunion symptoms does not respond to the conservative measures or if the bunion has progressed past a threshold where these measures are not effective, bunion surgery may be necessary to correct alignment and remove the bunion. A large range of types of surgical procedures for bunions are available and the choice will depend on things like what bone or bones are involved, the angular relationship between the different bones, the amount of damage to the joint and the presence of deformities other than the bunion.

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.
