Overview
Bunions are a common problem that most people experience as a bony protuberance at the base of the big toe. A bunion, however, is more complicated than simply a bump on the foot. When a patient has a bunion, the big toe angles in towards the other toes, a condition called hallux valgus. Bunions are most common in women. The skin over your big toe may be red and tender. Wearing any type of shoe may be painful. This joint flexes with every step you take. Your big toe may angle toward your second toe, or even move all the way under it. The skin on the bottom of your foot may become thicker and painful. Pressure from your big toe may force your second toe out of alignment, sometimes overlapping your third toe. If this condition gets severe, it may be difficult to walk. Your pain may become chronic and you may develop arthritis. Bunions tend to get progressively worse over time without treatment.
Causes
Bunions are sometimes genetic and consist of certain tendons, ligaments, and supportive structures of the first metatarsal that are positioned differently. This bio-mechanical anomaly may be caused by a variety of conditions intrinsic to the structure of the foot, such as flat feet, excessive flexibility of ligaments, abnormal bone structure, and certain neurological conditions. These factors are often considered genetic. Although some experts are convinced that poor-fitting footwear is the main cause of bunion formation, other sources concede that footwear only exacerbates the problem caused by the original genetic structure. Bunions are commonly associated with a deviated position of the big toe toward the second toe, and the deviation in the angle between the first and second metatarsal bones of the foot. The small sesamoid bones found beneath the first metatarsal (which help the flexor tendon bend the big toe downwards) may also become deviated over time as the first metatarsal bone drifts away from its normal position. Arthritis of the big toe joint, diminished and/or altered range of motion, and discomfort with pressure applied to the bump or with motion of the joint, may all accompany bunion development. Atop of the first metatarsal head either medially or dorso-medially, there can also arise a bursa that when inflamed (bursitis), can be the most painful aspect of the process.
Symptoms
The pain from a bunion is felt around the MTP joint of the big toe. People with bunions often complain of pain when they when they stand or walk for long periods of time. High heeled shoes or shoes with a small toe area can make bunions feel and look worse. As a result of the deformity the big toe can lose some of its range of motion or become stiff. Sometimes both feet are affected.
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
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.
Surgical Treatment
If the bunion symptoms does not respond to the conservative measures or if the bunion has progressed past a threshold where these measures are not effective, bunion surgery may be necessary to correct alignment and remove the bunion. A large range of types of surgical procedures for bunions are available and the choice will depend on things like what bone or bones are involved, the angular relationship between the different bones, the amount of damage to the joint and the presence of deformities other than the bunion.
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.
