Overview

A bunion, also known by its medical name hallux abductovalgus, is foot condition in which your big toe points toward your second toe, causing a bump or prominence to develop on the inside edge of your big toe and first metatarsal bone. Your first metatarsal bone is the long bone located directly behind your big toe, in your mid-foot. A bunion will cause your forefoot to appear wider because the base of your big toe now points away from your foot instead of pointing straight ahead.

Causes
You may get bunions if the way your foot is shaped puts too much pressure on your big toe joint. Because bunions can run in families, some experts believe that the inherited shape of the foot makes some people more likely to get them. Your foot rolls inward too much when you walk. A moderate amount of inward roll, or pronation, is normal. But damage and injury can happen with too much pronation. You have flat feet. You often wear shoes that are too tight. All of these may put pressure on the big toe joint. Over time, the constant pressure forces the big toe out of alignment, bending it toward the other toes.
SymptomsThe pain from a bunion is felt around the MTP joint of the big toe. People with bunions often complain of pain when they when they stand or walk for long periods of time. High heeled shoes or shoes with a small toe area can make bunions feel and look worse. As a result of the deformity the big toe can lose some of its range of motion or become stiff. Sometimes both feet are affected.

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
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.


Surgical Treatment
Surgery can be a very successful treatment for bunions and could be considered if you are having pain that is affecting your function on a regular basis, for instance, pain during sports or wearing work shoes. It is important, however, that you are seen by a consultant orthopaedic foot and ankle surgeon who has undergone specialist training with a foot and ankle fellowship. There are many different surgical techniques and it is important that your surgeon is expert in several of these so that you have the one that is best for your unique deformity. Bunion removal is usually done under general anesthesia. This means you will be asleep throughout the procedure. The operation can be performed as a day-case, but an overnight stay in hospital is sometimes required. Your surgeon will explain the benefits and risks of having bunion surgery, and will also discuss the alternatives treatments.

Prevention
Proper footwear may prevent bunions. Wear roomy shoes that have wide and deep toe boxes (the area that surrounds the toes), low or flat heels, and good arch supports. Avoid tight, narrow, or high-heeled shoes that put pressure on the big toe joint. Medicine will not prevent or cure bunions.
