Overview

A bunion, also known as hallux valgus, is a painful deformity that develops at the base of the big toe. Bunions are caused when the big toe pushes and bends inward towards the other toes. This displaces the bones of the joint, causing it to protrude in a way that looks like a large growth. Bunions develop due to a variety of factors. Some people inherit feet that are more susceptible due to their shape and structure, having flat feet for instance. But bunions can be made worse by the wrong shoe, or by carrying extra weight or prolonged periods of standing or walking.

Causes
Bunions are most often caused by an faulty foot mechanics. It is not the bunion itself that is inherited, but certain foot types that make a person prone to developing a bunion. Although wearing shoes that crowd the toes won't actually cause bunions in the first place, it sometimes makes the deformity get progressively worse. That means you may experience symptoms sooner.
SymptomsIf a foot bunion is developing, you may experience some of these symptoms. Bulge or bump on the outside of the base of your big toe. Swelling. Redness. Soreness. Thickening of the skin in that location. Corns or calluses. Limited movement of your big toe. Persistent or periodic pain. The pain you experience may be mild or severe. It may become increasingly difficult to walk in your normal shoes. The pressure on your other toes can cause your toenails to grow inward or your smaller toes to become bent.

Diagnosis
People with bunions may be concerned about the changing appearance of their feet, but it is usually the pain caused by the condition that leads them to consult their doctor. The doctor will evaluate any symptoms experienced and examine the affected foot for joint enlargement, tissue swelling and/or tenderness. They will also assess any risk factors for the condition and will ask about family history. An x-ray of the foot is usually recommended so that the alignment of big toe joint can be assessed. This would also allow any other conditions that may be affecting the joint, such as arthritis, to be seen.

Non Surgical Treatment
There are a number of treatment options for bunions. Non-surgical treatments are usually tried first, including painkillers, orthotics (insoles) and bunion pads. However, these can only help to reduce the symptoms of bunions, such as pain. They don't improve the appearance of your foot.


Surgical Treatment
Orthopaedic surgeons use many different surgical procedures to treat bunions. The common goal of these procedures is to realign the joint, relieve pain, and correct deformity. These procedures include repair of the Tendons and Ligaments Around the Big Toe. These tissues may be too tight on one side and too loose on the other, creating an imbalance that causes the big toe to drift toward the others. Often combined with an osteotomy, this procedure shortens the loose tissues and lengthens the tight ones. Removal of the damaged joint surfaces, followed by the insertion of screws, wires, or plates to hold the surfaces together until it heals. Used for patients with severe bunions, severe arthritis, and when other procedures have failed. Removal of the bump on the toe joint, used only for an enlargement of the bone with no drifting of the big toe. This procedure is seldom used because it rarely corrects the cause of the bunion. Removal of the damaged portion of the joint, used mainly for patients who are older, have had previous bunion surgery, or have severe arthritis. This creates a flexible "scar" joint. The surgical cutting and realignment of the joint. Your orthopaedic surgeon will choose the procedure best suited to your condition.
