Bunions (sometimes referred to as Hallux abducto valgus) are enlargements of the inner portion of the metatarsophalangeal (MTP) joint at the base of your big toe. More commonly, they are described as a bump on the side of the big toe. The foot bunion is the result of changes that occur in the framework of the bones at the front of your foot. Instead of pointing straight ahead, your big toe begins to lean into your second toe, throwing the bones out of alignment. Bunions are progressive, meaning you will not just wake up one day and find a visible bump (unless it was caused by a bug bite or something of that nature). Bunions are generally attributed to genetics and improper footwear. It may take years for a bunion to fully develop and begin to show symptoms. Some people may never experience symptoms at all. Bunions may begin to form during one?s teenage years, but they usually occur in people aged 20-30. Women are three times more likely than men to have bunions. Causes
While the precise cause is not known, there seem to be inherited (genetic) factors that lead to abnormal foot function like overpronation that can predispose to the development of bunions. This is especially common when bunions occur in younger individuals. This abnormal biomechanics can lead to instability of the metatarsal phalangeal joint and muscle imbalance resulting in the deformity. Although shoe gear doesn't directly cause a bunion, it can certainly make the bunion painful and swollen. Other less common causes of bunion deformities include trauma (sprains, fractures, and nerve injuries), neuromuscular disorders (polio or Charcot-Marie-Tooth disease) and limb-length discrepancies (one leg shorter than the other) where the longer leg develops the bunion.
Symptoms
Symptoms include redness, swelling and pain which may be present along the inside margin of the foot. The patients feet may become too wide to fit into their normal size shoes and moderate to severe discomfort may occur when the patient is wearing tight shoes. A "hammer toe" may occur at the 2nd toe. This is when the toe contracts and presses on the shoe. Subsequently, this may cause a corn on top of the 2nd toe.
Diagnosis
When an x-ray of a bunion is taken, there is usually angulation between the first metatarsal bone and the bones of the big toe. There may also be angulation between the first and second metatarsal bones. These angular irregularities are the essence of most bunions. In general, surgery for bunions aims to correct such angular deformities.
Non Surgical Treatment
Wear comfortable shoes that don't squeeze your toes together. Sandals are ideal in warm weather. Cushioning the bunion with a donut-shaped bunion pad sold at drugstores can prevent any direct rubbing against your shoes. Have your shoes stretched to give your foot more room or consider switching to footwear customized to relieve pressure on the affected area. Soak your foot in warm water to help lessen the pain after a day on your feet. Apply ice packs several times a day to reduce swelling of painful and inflamed bunions. Take aspirin or ibuprofen for the inflammation and pain, and try supplementing with anti-inflammatory herbs such as ginger and turmeric (these work more slowly than the drugs). See a podiatrist for specially fitted shoes or orthotic devices that may help. Sometimes, surgery is necessary. Seek a second opinion before scheduling any operation.
Surgical Treatment
Most bunions can be treated without surgery. But when nonsurgical treatments are not enough, surgery can relieve your pain, correct any related foot deformity, and help you resume your normal activities. An orthopaedic surgeon can help you decide if surgery is the best option for you. Whether you've just begun exploring treatment for bunions or have already decided with your orthopaedic surgeon to have surgery, this booklet will help you understand more about this valuable procedure.
Prevention
Bunions often become painful if they are allowed to progress. But not all bunions progress. Many bunion problems can be managed without surgery. In general, bunions that are not painful do not need surgical correction. For this reason, orthopaedic surgeons do not recommend ?preventive? surgery for bunions that do not hurt, with proper preventive care, they may never become a problem.
