Overview

The original definition of a bunion was a bursa (a fluid-filled sac) on the side of the foot near the base of the big toe. The bursa was caused by a chronic friction of the patient's first metatarsal bone (the bone to which the big toe attaches) and the shoe. Few people go by this definition any longer. Today most people consider a bunion to be the enlarged bone on the side of the foot that typically caused the bursa. Along with this bump, there is usually an associated mis-alignment of the big toe, with it leaning in towards the second toe. In medical jargon, the term for a bunion is "Hallux Abducto Valgus," or "HAV" for short. Though the condition is really slightly different, it may also be known as "Hallux Valgus." Bunions are usually a progressive problem, and can make it difficult to find shoes that fit. The condition is often quite uncomfortable, not only because of the pressure the shoes exert on the bump, but because of the other factors associated with bunions, which we shall discuss shortly.

Causes
A bunion is more common in women than men due to women wearing tighter fitting shoes. This condition can cause a variety of different soft tissue and bony complaints which may result in severe pain.
SymptomsBunions are readily apparent, you can see the prominence at the base of the big toe or side of the foot. However, to fully evaluate your condition, the Podiatrist may take x-rays to determine the degree of the deformity and assess the changes that have occurred. Because bunions are progressive, they don't go away, and will usually get worse over time. But not all cases are alike, some bunions progress more rapidly than others. There is no clear-cut way to predict how fast a bunion will get worse. The severity of the bunion and the symptoms you have will help determine what treatment is recommended for you.

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
Somtimes observation of the bunion is all that?s needed. A periodic exam and x-ray can determine if your bunion deformity is advancing. Measures can then be taken to reduce the possibility of permanent damage to your joint. In many cases, however, some type of treatment is needed. Conservative treatments may help reduce the pain of a bunion. These options include changes in shoe-wear. Wearing the right kind of shoes is very important. Choose shoes with a large toe box and avoid narrow high heeled shoes which may aggravate the condition. Padding. Pads can be placed over the area to reduce shoe pressure. Medication. Nonsteroidal anti-inflammatory drugs may help reduce inflammation and reduce pain. Injection therapy. Injection of steroid medication may be used to treat inflammation that causes pain and swelling especially if a fluid filled sac has developed about the joint. Orthotic shoe inserts. By controlling the faulty mechanical forces the foot may be stabilized so that the bunion becomes asymptomatic.


Surgical Treatment
Several surgical procedures are available to the podiatric physician The surgery will remove the bony enlargement, restore the normal alignment of the toe joint, and relieve pain.A simple bunionectomy, in which only the bony prominence is removed, may be used for the less severe deformity. Severe bunions may require a more involved procedure, which includes cutting the bone and realigning the joint. Recuperation takes time, and swelling and some discomfort are common for several weeks following surgery. Pain, however, is easily managed with medications prescribed by your podiatric physician.

Prevention
To minimize the chance of developing bunions, never force your feet into shoes that don?t fit. Choose a shoe that conforms to the shape of your foot. Opt for shoes with wider insteps, broad toes, and soft soles. Shoes that are short, tight, or sharply pointed should be avoided.
