Overview
A bunion (also called Hallux Valgus) is a painful swelling caused by deformity of the big toe. As this swelling is caused by a bone it can be very unforgiving in shoes, which can rub on it causing pain, particularly formal foot shoes or high heels. Arthritis, or wearing tight or ill-fitting shoes over a period of many years, may increase the risk of bunions. However, they can have other causes. Bunions are more common in women and sometimes run in families.
Causes
Various factors, including a tight gastrocnemius (or calf) muscle and instability of the arch, contribute to formation of bunions. The tight calf muscle is often hereditary and can cause a bunion because it forces more loading, or pressure, on the forefoot. Ultimately, this can contribute to instability in the bones, ligaments and tendons that form the arch. When it?s unstable, the arch starts collapsing and the metatarsal can shift. Arch instability can also be brought on by obesity, again, due to chronic overloading of the foot. But, by far, the most common contributing factor is childbirth. Bunions are most common in women who have had children. This happens because the hormones that affect their pelvis during childbirth also affect their feet. The hormone is called relaxin, and it allows bones to move and spread. Over time, it can cause the structure of a woman?s feet to gradually stretch and the metatarsal to shift.
Symptoms
Symptoms of a bunion include irritated skin, sensitivity to touch, and pain when walking or running. Since the bunion may grow so prominent as to affect the shape of the foot, shoes may no longer fit properly, and blisters may form at the site of friction and pressure. Bunions may grow so large that an individual must wear shoes that are a larger size than they would otherwise wear. If the bunion becomes a severe case, walking may become difficult.
Diagnosis
Looking at the problem area on the foot is the best way to discover a bunion. If it has the shape characteristic of a bunion, this is the first hint of a problem. The doctor may also look at the shape of your leg, ankle, and foot while you are standing, and check the range of motion of your toe and joints by asking you to move your toes in different directions A closer examination with weight-bearing X-rays helps your doctor examine the actual bone structure at the joint and see how severe the problem is. A doctor may ask about the types of shoes you wear, sports or activities (e.g., ballet) you participate in, and whether or not you have had a recent injury. This information will help determine your treatment.
Non Surgical Treatment
Treatment for bunions ranges from non-surgical to surgical. Conservative, non-surgical treatments are aimed to help alleviate some of the discomfort and pain from the bunion, they will not fix the problem. Some of the recommendations would be shoe modification to make room for the bunion, wearing wide toed shoes, or adding padding and cushioning to your shoes.
Surgical Treatment
Severe cases may require, along with surgery, cast immobilization and prolonged avoidance of weight-bearing activity. You should know that undergoing surgery for this health problem does not guarantee a cure or even a beneficial health outcome. Bunions, like many other foot conditions, should always be approached from a prevention standpoint, or therapy should be directed at slowing the progression of your deformity.
Prevention
Shoes that possess tapering toe boxes should be avoided if you have a bunion, as narrow toe boxes will hasten the progression of your bunion deformity. In some cases, conservative measures, including switching to appropriate footwear, may not have the desired effect, and your podiatrist may recommend for you a surgical procedure known as a bunionectomy.
