Overview

The term ?bunion,? as it is popularly used, describes a variety of deformities involving a painful prominence and swelling at the base of the big toe. Orthopaedists use additional terms to describe the different deformities. The condition in which the big toe deviates from the normal position toward the direction of the second toe is referred to as hallux valgus. Dorsal bunions are a different variety in which the prominence appears on the top of the base of the toe, often the result of an arthritic joint.

Causes
There is some debate about the main cause of foot bunion pain, but they tend to fall into 2 categories. Genetics. There is a definite genetic link, meaning that if someone in your family suffers from a hallux abducto valgus, there is a high chance that you will too, although this is not always the case. It may be due to an abnormal foot position such as flat feet, or a medical condition such as hypermobility (where your joints are overly flexible) or arthritis (e.g. rheumatoid arthritis or gout). Regularly wearing high heels with a pointed toe puts you at high risk for developing foot bunions. Ill-Fitting Footwear. Poorly fitting shoes are thought to be the other common cause of foot bunion pain. Frequent wear of tight fitting shoes or high heels places excessive pressure on the big toe pushing it into the classic hallux abducto valgus position.
SymptomsBunions may or may not cause symptoms. A frequent symptom is foot pain in the involved area when walking or wearing shoes; rest relieves this pain. A bunion causes enlargement of the base of the big toe and is usually associated with positioning of the big toe toward the smaller toes. Shoe pressure in this area can cause interment pain while the development of arthritis in more severe bunions can lead to chronic pain. Bunions that cause marked pain are often associated with swelling of the soft tissues, redness, and local tenderness. It is important to note that, in postpubertal men and postmenopausal women, pain at the base of the big toe can be caused by gout and gouty arthritis that is similar to the pain caused by bunions.

Diagnosis
Although bunions are usually obvious from the pain and unusual shape of the toe, further investigation is often advisable. Your doctor will usually send you for X-rays to determine the extent of the deformity. Blood tests may be advised to see if some type of arthritis could be causing the pain. Based on this evaluation, your doctor can determine whether you need orthopaedic shoes, medication, surgery or other 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
If surgery is required to correct a symptomatic bunion, there are several procedures that may be used, depending on the size and degree of the deformity. For mild deformities, a simple shaving of the bony prominence may suffice. At the same time, the tissues on the inner, or medial, side of the joint are tightened to hold the great toe in a more neutral alignment. When only the bone is shaved, this procedure is commonly referred to as a ?Silver? procedure. When the bone is shaved and the soft tissues tightened, this is called a ?modified McBride? procedure.
