Overview

A bunion, or Hallux Valgus, is a foot deformity characterised by deviation of the bones around the big toe joint of the foot. As a result, there is a large exostosis or bony lump on the inside of the foot and the toe is pointed across towards the smaller toes. It is a common problem, more so in women and has been attributed to tight fitting footwear. This article will cover the basics of bunions, what it is due to, and what treatment is available.

Causes
Bunions can be caused by improper footwear. Genetics. Foot injuries. Congenital deformities. Medical conditions such as arthritis. Stress on feet. Bunions are mainly caused by genetics. The bunion itself is not inherited, but the person?s hereditary foot type and gait pattern makes them more prone to developing bunions.You can also begin to develop bunionsby wearing shoes that are too tight or too small. When you wear shoes of this nature, your toes are squeezed together. Bunions are not caused by crowding of the toes, but wearing tight shoes can worsen the condition and cause symptoms to appear sooner. Some people are born with birth defects that put them at higher risk for developing bunions.
SymptomsWith Bunions, a person will have inflammation, swelling, and soreness on the side surface of the big toe. Corns most commonly are tender cone-shaped patches of dry skin on the top or side of the toes. Calluses will appear on high-pressure points of the foot as thick hardened patches of skin.

Diagnosis
X-rays are the best way to determine the amount of deformity of the MTP joint. Blood work may be required to rule out other diseases that may be associated with bunions such as rheumatoid arthritis. Other tests such as bone scans or MRI's are not usually required.

Non Surgical Treatment
The initial treatment of a bunion should be non-operative. Symptoms can often be greatly improved with simple non-operative interventions. Non-operative treatment may include properly fitted shoes, Properly fitting comfort shoes with a wide non-constrictive toe box, especially one that is made out of a soft material such as leather, can be quite helpful in reducing the irritation over the prominent bunion. In some instances, it is helpful to have a shoemaker stretch the inside aspect of the shoe. Jamming a foot with a bunion into a constrictive shoe will likely lead to the development of uncomfortable symptoms. Bunion pads, Medial bunion pads may also be helpful in decreasing the symptoms associated with the bunion. These pads can be obtained at many drugstores. Essentially, they serve to lessen the irritation over the medial prominence and, thereby, decrease the associated inflammation This should be combined with comfortable non-constrictive shoes. A toe spacer placed between the great toe and the second toe can help to reduce the bunion deformity and, thereby, decrease the stretch on the medial tissue and the irritation associated with the bunion. Toe spacers can be obtained at most drug stores or online. Soft shoe inserts. Over-the-counter accommodative orthotics may also help bunion symptoms. This product is particularly helpful if bunion symptoms include pain that is under the ball of the foot. Orthotics with a slight medial longitudinal arch may be helpful for patients that have associated flatfoot deformity. These can be purchased at many sports stores, outdoors stores, or pharmacies. Bunion splints have often been used to treat the symptoms associated with hallux valgus. These splints are typically worn at night in an effort to reduce the bunion deformity. There is no evidence to suggest that these splints decrease the rate at which bunion deformities occur. There is also no evidence that clearly supports their effectiveness. However, some patients report good relief with the use of these splints.


Surgical Treatment
As you explore bunion surgery, be aware that so-called "simple" or "minimal" surgical procedures are often inadequate "quick fixes" that can do more harm than good. And beware of unrealistic claims that surgery can give you a "perfect" foot. The goal of surgery is to relieve as much pain, and correct as much deformity as is realistically possible. It is not meant to be cosmetic. There are several techniques available, often as daycare (no in-patient stay), using ankle block local anaesthetic alone or combined with sedation or full general anaesthesia. Most of the recovery occurs over 6-8 weeks, but full recovery is often longer and can include persistent swelling and stiffness. The surgeon may take one or more of the following steps in order to bring the big toe back to the correct position: (a) shift the soft tissue (ligaments and tendons) around the joint and reset the metatarsal bone (osteotomy), remove the bony bump and other excess bone or (b) remove the joint and connect (fuse) the bones on the two side of the joint (fusion). These are just a few examples of the many different procedures available and your treating surgeon can help you decide the best option for you.
