Overview

The term hallux valgus actually describes what happens to the big toe. Hallux is the medical term for big toe, and valgus is an anatomic term that means the deformity goes in a direction away from the midline of the body. So in hallux valgus the big toe begins to point towards the outside of the foot. As this condition worsens, other changes occur in the foot that increase the problem. One of those changes is that the bone just above the big toe, the first metatarsal, usually develops too much of an angle in the other direction. This condition is called metatarsus primus varus. Metatarsus primus means first metatarsal, and varus is the medical term that means the deformity goes in a direction towards the midline of the body. This creates a situation where the first metatarsal and the big toe now form an angle with the point sticking out at the inside edge of the ball of the foot. The bunion that develops is actually a response to the pressure from the shoe on the point of this angle. At first the bump is made up of irritated, swollen tissue that is constantly caught between the shoe and the bone beneath the skin. As time goes on, the constant pressure may cause the bone to thicken as well, creating an even larger lump to rub against the shoe.

Causes
While there isn?t really one exact cause of bunions, podiatric physicians tend to agree that a bunion is formed when the normal mechanics of the foot are disrupted. This can happen in any number of ways. Abnormality in foot function or foot mechanics. In general, this means a pronated foot (one with an excessive rolling to the outside when the patient is walking, running or doing any kind of activity), a flat foot or low-arched foot. This is probably the most common cause, and it?s where the idea of heredity comes into play. Foot mechanics, and problems with them, tend to run in families. The good news is that there are orthoses and corrective shoes that can effectively alleviate these and other disturbances to foot mechanics, before they contribute to bunions. A podiatric physician can prescribe the best corrective footwear and shoe inserts for all activities, work, exercise, play, walking, shopping and more, based on an analysis of the patient?s foot and his or her lifestyle.
SymptomsMany people with bunions suffer from discomfort and pain from the constant irritation, rubbing, and friction of the enlargement against shoes. The skin over the toe becomes red and tender. Because this joint flexes with every step, the bigger the bunion gets, the more it hurts to walk. Over time, bursitis or arthritis may set in, the skin on the bottom of the foot may become thicker, and everyday walking may become difficult-all contributing to chronic bunion pain.

Diagnosis
Before examining your foot, the doctor will ask you about the types of shoes you wear and how often you wear them. He or she also will ask if anyone else in your family has had bunions or if you have had any previous injury to the foot. In most cases, your doctor can diagnose a bunion just by examining your foot. During this exam, you will be asked to move your big toe up and down to see if you can move it as much as you should be able to. The doctor also will look for signs of redness and swelling and ask if the area is painful. Your doctor may want to order X-rays of the foot to check for other causes of pain, to determine whether there is significant arthritis and to see if the bones are aligned properly.

Non Surgical Treatment
The treatment method your doctor chooses for you will be based on the severity of the bunion. Treatment can be simple and non-surgical or it can be complex, surgical, and costly. A bunion is permanent unless surgery is performed to remove it, but self-care can help to improve your symptoms. If you suspect that a bunion is developing, you should seek medical attention immediately. Here are the most common conservative treatment options. Changing your shoes. Adding custom orthotics to your shoes. Medication such as Tylenol for pain relief. Padding and taping to put your foot in its normal position. Applying ice or cold compresses to reduce swelling and pain. Keeping pressure off your affected toe, especially if there is swelling, redness, and pain. Before bed, separate the affected toe from the others with a foam-rubber pad and leave it there while you sleep.


Surgical Treatment
If non-surgical treatments fail to relieve bunion pain and when the pain of a bunion interferes with daily activities, it?s time to discuss surgical options with a foot and ankle surgeon. Together you can decide if surgery is best for you. A variety of surgical procedures is available to treat bunions. The procedures are designed to remove the ?bump? of bone, correct the changes in the bony structure of the foot, and correct soft tissue changes that may also have occurred. The goal of surgery is the reduction of pain. In selecting the procedure or combination of procedures for your particular case, the foot and ankle surgeon will take into consideration the extent of your deformity based on the x-ray findings, your age, your activity level, and other factors. The length of the recovery period will vary, depending on the procedure or procedures performed.
