A bunion is a very common foot deformity that develops over the first metatarsal phalageal joint of the big toe of the foot. The joint that joins the big toe to the foot is called the first MTP joint. When it becomes prominent and the big toe starts to become crooked this is known as a bunion. The term referring to deformity of the big toe as it becomes crooked is called Hallux Valgus. It is the bump itself that is known as the bunion. When it gets red and swollen over the bunion because it gets sore this is usually due to an inflamed soft tissue over the underlying bone.
The most common cause of bunions is wearing shoes that are too tight. The condition is not hereditary, but it does tend to run in families-often due to a faulty foot structure. Other causes of this condition might be neuromuscular problems, flat feet, pronated feet, or foot injuries.
A bulging bump on the outside of the base of your big toe. Swelling, redness or soreness around your big toe joint aggravated by footwear. Red, calloused skin along the inside edge of the big toe. Corns or calluses under the ball of the foot or where the first and second toes overlap. Persistent or intermittent pain. Restricted movement of your big toe.
Generally, observation is adequate to diagnose a bunion, as the bump is obvious on the side of the foot or base of the big toe. However, your physician may order X-rays that will show the extent of the deformity of the foot.
Non Surgical Treatment
Wearing good footwear does not cure the deformity but may ease symptoms of pain and discomfort. Ideally, get footwear advice from a person qualified to diagnose and treat foot disorders (podiatrist - previously called a chiropodist). Advice may include wear shoes, trainers or slippers that fit well and are roomy. Don't wear high-heeled, pointed or tight shoes. You might find that shoes with laces or straps are best, as they can be adjusted to the width of your foot. Padding over the bunion may help, as may ice packs. Devices which help to straighten the toe (orthoses) are still occasionally recommended, although trials investigating their use have not found them much better than no treatment at all. Painkillers such as paracetamol or ibuprofen may ease any pain. If the bunion (hallux valgus) develops as part of an arthritis then other medication may be advised. A course of antibiotics may be needed if the skin and tissues over the deformity become infected.
The choice of surgical procedures (bunionectomy) is based on a biomechanical and radiographic examination of the foot. Because there is actual bone displacement and joint adaptation, most successful bunionectomies require cutting and realigning the 1st metatarsal (an osteotomy). Simply "shaving the bump" is often inadequate in providing long-term relief of symptoms and in some cases can actually cause the bunion to progress faster. The most common procedure performed for the correction of bunions is the 1st metatarsal neck osteotomy, near the level of the joint. This refers to the anatomical site on the 1st metatarsal where the actual bone cut is made. Other procedures are preformed in the shaft of the metatarsal bone (see procedures preformed in the shaft of the metatarsal) and still other procedures are selected by the surgeon that are preformed in the base of the metatarsal bone (see surgeries preformed in the base of the metatarsal).
To help prevent bunions, select your style and size of shoes wisely. Choose shoes with a wide toe area and a half-inch of space between the tip of your longest toe and the end of the shoe. Shoes also should conform to the shape of your feet without causing too much pressure.
