Foot Bunions Cause

Overview
Bunions Callous A simple bunion is an abnormal bump of bone that is formed at the head of our old friend, the first metatarsal bone. The bunion can either be on the top or side of the first metatarsal bone. In a more advanced bunion deformity, called Hallux Abducto Valgus, there starts to be a movement of the big toe toward the second toe. The most severe bunion is when the first toe not only moves toward the second toe, but it overlaps or underlaps the second toe. Bunions can cause swelling of the feet to occur.

Causes
Contributing factors may include excessive foot pronation, wearing tight and pointed-toe shoes, and occasionally trauma. Joint misalignment causes osteoarthritis with cartilage erosion and exostosis formation, resulting in joint motion being limited (hallux limitus) or eliminated (hallux rigidus). In late stages, synovitis occurs, causing joint swelling. In reaction to pressure from tight shoes, an adventitious bursa can develop medial to the joint prominence, which can become painful, swollen, and inflamed.

Symptoms
Since the pain from a bunion is always aggravated by shoe wear, the symptoms will often depend on the type and size of shoes worn. The perception of pain or discomfort that people experience is quite varied. There are some individuals who have small bunions that are very uncomfortable. This limits their ability to wear shoes comfortably. On the other hand, some individuals may have quite significant deformities that are annoying but do not limit their activities in anyway.

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
Treatment falls into two broad categories, conservative and surgical. From a conservative standpoint, efforts are directed at correcting faulty foot mechanics with custom molded insoles and relief of symptoms. These include Custom Orthosis to stabilize the abnormal motion of the hind and fore foot. Shoe gear modification: Using shoes with larger toe boxed and more supple materials. Changes in activities. Try to avoid those things which cause symptoms. Anti-inflammatory medication for periodic relief this includes cortisone injections into the joint as well as oral medication. Bunions

Surgical Treatment
Bunion surgery involves realigning the joint into a better position. The procedure is usually performed under a general anaesthetic so the patient is not awake during the operation. A bunion causes a prominent bone over the inside of the joint between the foot and the big toe known as the 1st metatarso-phalangeal joint. It gives the appearance of the big toe pointing in towards the others. Surgery is a last resort treatment option in severe cases where walking or wearing shoes is painful.
