A foot bunion is when the big toe gradually deviates inwards towards the second toe and in severe cases may even start to cross over the top or underneath. As the top of the toe moves inwards, the base of the toe (the knuckle part), pushes outwards producing the characteristic lump on outer side of the big toe. The medical term for a foot bunion at the big toe is a hallux abducto valgus, or hallux valgus. ?Hallux? means big toe, ?abducto? means to move away from the midline and ?valgus? refers to the abnormal angle of the toe. Foot bunions can also occur in the little toe, where they are known as a bunionette, but these are much less common. Causes
Shoes with narrow toes can trigger a bunion, but they?re not the underlying cause. Bunions run in families, because foot type (shape and structure) is hereditary, and some types are more prone to bunions than others. Low arches, flat feet, and loose joints and tendons all increase the risk. The shape of the metatarsal head (the top of the first metatarsal bone) also makes a difference: if it?s too round, the joint is less stable and more likely to deform when squeezed into shoes with narrow toes. Symptoms
With 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
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
If you suspect a bunion, it is essential that you confirm your suspicions by consulting with a podiatric physician. Don?t try to treat the problem yourself, even by using conservative measures. Many conditions have similar symptoms, and only a professional can tell the difference. Once a diagnosis is obtained, it is essential to begin treatment immediately. Your podiatric physician will advise you on the most effective means. If caught early enough, good foot care, shoes that fit properly, and/or orthoses may eliminate the need for any further intervention. Certain over-the-counter remedies, such as felt or foam pads, applied to specific areas of the foot to relieve pressure and friction, will protect the bunion. Elevating the foot and icing the area for 20 minutes an hour may help to relieve pain. 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. Prevention
The best protection against developing bunions is to protect and care for your feet every day. Avoid tight and narrow-fitting shoes. Limit your use of high heels. Wear comfortable shoes with adequate space between your longest toe and the end of the shoe. Getting treatment for very flat or very high-arched feet (if you are experiencing symptoms) will give your feet the proper support and help maintain stability and balance.
