Do Bunions Need Surgical Treatment?
OverviewA foot bunion is a common cause of foot pain caused by deformity of one of the toe bones. They most commonly affect the big toe, known as hallux abducto valgus, but can also affect the little toe, known as a bunionette. The classic presentation is a large bump on the outer side of the big toe that is red, swollen and painful caused by the toe deviating across towards the second toe. Left untreated, the condition usually gets gradually worse, so it is important to get treatment early on else you may end up needing bunion surgery. CausesBunions most commonly affect women. Some studies report that bunions occur nearly 10 times more frequently in women. It has been suggested that tight-fitting shoes, especially high-heel and narrow-toed shoes, might increase the risk for bunion formation. Bunions are reported to be more prevalent in people who wear shoes than in barefoot people. While the precise causes are not known, there also seems to be inherited (genetic) factors that predispose to the development of bunions, especially when they occur in younger individuals. Other risk factors for the development of bunions include abnormal formation of the bones of the foot at birth (congenital), nerve conditions that affect the foot, rheumatoid arthritis, and injury to the foot. Bunions are common in ballet dancers. SymptomsJust because you have a bunion does not mean you will necessarily have pain. There are some people with very severe bunions and no pain and people with mild bunions and a lot of pain. Symptoms for a bunion may include pain on the inside of your foot at the big toe joint, swelling on the inside of your foot at the big toe joint, appearance of a "bump" on the inside edge of your foot. The big toe rolling over to one side. Redness on the inside of your foot at the big toe joint. Numbness or burning in the big toe (hallux). Decreased motion at the big toe joint. Painful bursa (fluid-filled sac) on the inside of your foot at the big toe joint. Pain while wearing shoes - especially shoes too narrow or with high heels. Joint pain during activities. Other conditions which may appear with bunions include Corns in between the big toe and second toe. Callous formation on the side or bottom of the big toe or big toe joint. Callous under the second toe joint. Pain in the second toe joint. DiagnosisYour doctor will be able to diagnose a bunion by asking about your symptoms and examining your feet. You may also have blood tests to rule out any other medical conditions, such as rheumatoid arthritis or gout, although this is rare. Your doctor may refer you to a podiatrist or chiropodist (healthcare professionals who specialise in conditions that affect the feet). Non Surgical TreatmentPatients should immediately cease using improperly fitted shoes. Footwear selection should have a wide and roomy toebox to accommodate the full width of the foot. If the problem is the over-pronation, the patient should be fitted with orthotics and can expect a slow recovery from pain over a period of months. Orthotics will not cause the physical deformity to regress, but will simply arrest any further progression and likely stop the pain. It is important to note however, that when bunions are severe and require surgery, the bunion can be corrected, but will develop again unless the root cause of over-pronation is corrected. If over-pronation is the root cause, orthotics will still be necessary. Surgical TreatmentSurgery can be a very successful treatment for bunions and could be considered if you are having pain that is affecting your function on a regular basis, for instance, pain during sports or wearing work shoes. It is important, however, that you are seen by a consultant orthopaedic foot and ankle surgeon who has undergone specialist training with a foot and ankle fellowship. There are many different surgical techniques and it is important that your surgeon is expert in several of these so that you have the one that is best for your unique deformity. Bunion removal is usually done under general anesthesia. This means you will be asleep throughout the procedure. The operation can be performed as a day-case, but an overnight stay in hospital is sometimes required. Your surgeon will explain the benefits and risks of having bunion surgery, and will also discuss the alternatives treatments. PreventionBunions 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.
