What Causes Bunions?

Overview
Bunions Callous Though a bunion is often described as a painful bump, this condition is much more complex than a simple bump on the side of the toe. X-rays show the true nature of the deformity and are used to help in the decision making process. Ranges of motion of joints associated with the toe are also performed to assess the deformity. There are many procedures for correcting a bunion and choosing the right one based on the examination increases the chance of success. The procedure performed on one person may not be the procedure required to give another a good result. In general, more severe bunion deformities require more extensive surgery and more extensive post-operative limitations. It is very important to note that the same instability and incorrect motion that causes a bunion also causes degeneration of the joint surfaces (osteoarthritis). Correction of the bunion cannot repair the damage done within the joint and continued pain from that separate process may occur. Realigning the joint may slow the damage within the joint and improve motion, but it may not alleviate all pain.

Causes
Bunions are a common problem that can cause foot pain and difficulty wearing shoes. Bunions occur in about 30% of the population of most Western countries. They are seen most commonly in women and become more common as people get older. Patients with bunions generally have one of two problems that can cause pain. As the big toe becomes more and more angled (pointing toward the other toes), the base of the toe becomes more and more prominent, forming the bunion. The bunion forms in part because of the new angle of the toe, and in part due to inflammation over the bunion surface. As the inflammation worsens, people can experience pain with shoe wear and walking. The big toe may eventually come to lie over, or more commonly under, the second toe. This may cause further irritation while wearing shoes and more pain. The second toe of patients who have bunions commonly forms a hammer toe.

Symptoms
The symptoms of hallux valgus usually center on the bunion. The bunion is painful. The severe hallux valgus deformity is also distressing to many and becomes a cosmetic problem. Finding appropriate shoe wear can become difficult, especially for women who want to be fashionable but have difficulty tolerating fashionable shoe wear. Finally, increasing deformity begins to displace the second toe upward and may create a situation where the second toe is constantly rubbing on the shoe.

Diagnosis
Your doctor will be able to diagnose a bunion by asking about your symptoms and examining your feet. You may also have blood tests to rule out any other medical conditions, such as rheumatoid arthritis or gout, although this is rare. Your doctor may refer you to a podiatrist or chiropodist (healthcare professionals who specialise in conditions that affect the feet).

Non Surgical Treatment
Technically, you can only ?fix a bunion? with surgery, but many patients don't need it to get symptom relief. In its early stages, the progression of the bunion deformity can often be dramatically slowed. Removing pressure from the bunion area and balancing the tendon and ligament alignment are the primary goals of mild bunion treatment. For example, it is important to wear shoes that have sufficient room in the toe area to accommodate the bunion - that means softer leather shoes to mold to the deformity and platform type heels for better foot and arch support. Your doctor may also advise the use of pads to protect the bunion from shoe pressure. Customized shoe inserts, called orthotics are made exclusively for your foot and are often used to correct the alignment of the arch and big toe joint. In some cases, physicians also use anti-inflammatory creams around the bunion. Bunions Hard Skin

Surgical Treatment
There are a number of different surgical procedures used to treat bunions. The type of surgery recommended for you will depend on the severity of the deformity. Your surgeon may use pins, wires or screws to hold the bones in place while they heal. Depending on the type of surgery you have, these may be left in your foot or removed later on. Some of the surgical procedures for bunions are described below. Osteotomy is the most commonly used and proven type of bunion surgery. Although there are many different types of osteotomy, they generally involve cutting and removing part of the bone in your toe. During the procedure, your surgeon will remove the bony lump and realign the bones inside your big toe. They'll also move your toe joint back in line, which may involve removing other pieces of bone, possibly from the neighbouring toes. A procedure called distal soft tissue realignment may be combined with an osteotomy. This involves altering the tissue in your foot to help correct the deformity and improve the stability and appearance of the foot.
