A bunion is a foot deformity where your big toe slants outward horizontally, pushing the tip of the big toe up against your little toes, and creating a characteristic sharp angle along the inside of your foot, at what?s called the first metatarsophalangeal joint-where your big toe connects to your foot. The reason for the deformity is an abnormal growth of bone, so it is not a condition that will correct itself naturally. Though bunions, or hallux valgus, as they are known in the medical community, are well-known among the general population for causing pain and discomfort, they can have a big impact on your running as well. Women?s marathon world record holder Paula Radcliffe, for example, lost several months of running because of a bunion on her foot. Causes
People born with abnormal bones (congenital) in their feet. Inherited foot type. Foot injuries. Inflammatory or degenerative arthritis causing the protective cartilage that covers your big toe joint to deteriorate. Wearing high heels forces your toes into the front of your shoes, often crowding your toes. Wearing shoes that are too tight, too narrow or too pointed are more susceptible to bunions. Pain from arthritis may change the way you walk, making you more susceptible to bunions. Occupation that puts extra stress on your feet or job that requires you to wear ill-fitting shoes. The tendency to develop bunions may be present because of an inherited structural foot defect.
Symptoms
The symptoms of bunions include irritated skin around the bunion, pain when walking, joint redness and pain, and possible shift of the big toe toward the other toes. Blisters may form more easily around the site of the bunion as well. Having bunions can also make it more difficult to find shoes that fit properly; bunions may force a person to have to buy a larger size shoe to accommodate the width the bunion creates. When bunion deformity becomes severe enough, the foot can hurt in different places even without the constriction of shoes because it then becomes a mechanical function problem of the forefoot.
Diagnosis
Your doctor will ask questions about your past health and carefully examine your toe and joint. Some of the questions might be: When did the bunions start? What activities or shoes make your bunions worse? Do any other joints hurt? The doctor will examine your toe and joint and check their range of motion. This is done while you are sitting and while you are standing so that the doctor can see the toe and joint at rest and while bearing weight. X-rays are often used to check for bone problems or to rule out other causes of pain and swelling. Other tests, such as blood tests or arthrocentesis (removal of fluid from a joint for testing), are sometimes done to check for other problems that can cause joint pain and swelling. These problems might include gout , rheumatoid arthritis , or joint infection.
Non Surgical Treatment
Depending on how many of the causative factors are true, a series of exercises to ensure correct alignment and stability of the lower limb should be implemented. Supportive foot wear with correct width and arch support can provide relief -shoes such as ballet flats, thongs (flip flops) and Ugg boots (or slippers) should be avoided. Mobilization of the mid foot to help re-align the toe correctly, and then taping and padding in the shoe to keep the toe in alignment. Taping to help draw the 1st metatarsal back in towards the second and correct any rotation and drop of the 1st metatarsal. Foam padding shaped like a donut to off load the pressure on the outside of the big toe.
Surgical Treatment
For severe bunions, outpatient surgery may be recommended. Within hours after surgery, you?ll be on your way home and ready for recovery. Your foot will be bandaged following surgery and placed in a surgical shoe which allows you to remain mobile. Immediate weight bearing without the use of casting or crutches is standard post- operative recovery for bunions. In most cases, the majority of healing should occur within a few weeks and you can resume normal activity within a short period of time. Bunion surgery can both reduce pain and improve the appearance of your feet. After surgery it is important to see your podiatrist as scheduled and follow all recovery instructions.
Prevention
If the diagnosis is made early on, such as in preadolescence, bunion development can be slowed and in some cases arrested with the proper supportive shoe gear and custom functional shoe inserts (orthotics). Avoidance of certain athletic activities with improper shoe fit and toe pressure can prevent the symptoms that occur with bunions.
