A bunion is one problem that can develop due to hallux valgus, a foot deformity. The term "hallux valgus" is Latin and means a turning outward (valgus) of the big toe (hallux). The bone which joins the big toe, the first metatarsal, becomes prominent on the inner border of the foot. This bump is the bunion and is made up of bone and soft tissue.
The underlying cause is a deformity of the joint at the base of the big toe. The deformity is called hallux valgus. In this deformity the joint develops a prominent sideways angle. Due to this deformity the bones of the big toe are pushed towards the smaller toes. The skin over the angled joint then tends to rub on the inside of shoes. This may cause thickening and inflammation of the overlying skin and tissues next to the affected joint. In most cases it is not clear why a hallux valgus deformity develops. There may be some hereditary (genetic) tendency to have a weakness of this joint. In some cases it is associated with a joint problem such as osteoarthritis or rheumatoid arthritis. However, whatever the underlying cause, wearing tight or badly fitting shoes tends to make the problem worse. Wearing such shoes puts extra pressure on the big toe joint and causes friction on the overlying skin.
A bunion, also called a hallux valgus, is a bony prominence on the inside of the big toe, caused by a misalignment of the joint. The overlying skin maybe swollen, red and tender. Bunions are often painful and can limit what shoes you can wear.
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
There is no way to eliminate existing bunions except to have them surgically removed. There are nonsurgical measures you can take to alleviate the pain and prevent your bunions from increasing in severity, and for that reason it's important to see your doctor before they become a serious problem. The more extensive your bunions are, the less effective nonsurgical treatments are. On the other hand, most bunions can be dealt with without surgery through wearing roomier, low-heel shoes, padding and taping your feet, using medications for pain control, going to physical therapy to relieve inflammation and wearing orthotics in your shoes to correct mechanical problems. Bunions that are not causing pain generally aren't appropriate for surgery. Roomier shoes. You should seek out shoes that conform to the shape of your feet as much as possible and provide plenty of room in the toe box, ensuring that your toes are not pinched or squeezed. You should make sure that, while standing, there is a half inch of space for your longest toe at the end of each shoe. Make sure the ball of your foot fits comfortably in the widest part of the shoe. Feet normally swell during the course of the day, so shop for shoes at the end of the day, when your feet are at their largest. Don't be vain about your shoe size, sizes vary by brand, so concentrate on making certain your shoes are comfortable. Remember that your two feet are very likely to be different sizes and fit your shoe size to the larger foot. Low-heel shoes. High heels shift all your body weight onto your toes, increasing the pressure on your toes and their joints tremendously. Instead, wear shoes with low (less than two inches) or flat heels that fit your foot comfortably. Padding and Taping. Padding the bunion can minimize pain and allow you to walk more normally. Specially designed pads for this are available at most drugstores. Taping your foot can reduce stress and pain in it by helping it stay in a more normal position. Medication. Anti-inflammatory drugs such as aspirin and ibuprofen can help deal with pain and inflammation caused by your bunion. Cortisone injections may be prescribed for the same purpose. If your bunion is a consequence of arthritis in the MTP joint, your physician may prescribe medications for that. Physical Therapy. Ultrasound treatments and whirlpool baths can help reduce pain and inflammation in bunions and related tissues. Orthotics are shoe inserts that can help correct mechanical foot-motion problems to reduce pain and prevent worsening of your bunion. Other measures. Icing and elevating your foot when your bunion is painful may help. Having your shoes stretched at a shoe repair shop may help also.
An operation may be advised if a change of footwear does not ease symptoms. The aim of the operation is to straighten the joint as much as possible and relieve pain. It is not usually done just to improve appearance. It can be done using a local or a general anaesthetic and you are usually out of hospital the same day. The operation chosen by the specialist depends on the severity of the bunion, the shape of your foot, and other factors, such as if you have arthritis in the joint. There are many different types of operation which are used to treat bunions. These range from operations to trim parts of the joint, to a total artificial replacement of the big toe joint (similar to a knee or a hip replacement). A common surgical procedure used is called a scarf osteotomy (osteotomy means a cut in the bone). An operation is usually successful at easing symptoms, but not in all cases. It is not always possible to relieve the pain completely or make the toe perfectly straight. Your specialist will be able to advise on the pros and cons of surgery, and the success rate of the chosen operation. Continued pain, infection and the bunion returning are some of the complications of surgery of which you need to be aware. You will need to continue to wear sensible, wide-fitting shoes for six months after the operation.
