What Could Cause Bunions?
A bunion is an unnatural, bony hump that forms at the base of the big toe where it attaches to the foot. Often, the big toe deviates toward the other toes. When this occurs, the base of the big toe pushes outward on the first metatarsal bone, which is the bone directly behind the big toe, forming a bunion. If this happens on the little toe and fifth metatarsal, it's called a bunionette. Because a bunion occurs at a joint, where the toe bends in normal walking, your entire body weight rests on the bunion at each step. Bunions can be extremely painful. They're also vulnerable to excess pressure and friction from shoes and can lead to the development of calluses.
People born with abnormal bones (congenital) in their feet. Inherited foot type. Foot injuries. Inflammatory or degenerative arthritis causing the protective cartilage that covers your big toe joint to deteriorate. Wearing high heels forces your toes into the front of your shoes, often crowding your toes. Wearing shoes that are too tight, too narrow or too pointed are more susceptible to bunions. Pain from arthritis may change the way you walk, making you more susceptible to bunions. Occupation that puts extra stress on your feet or job that requires you to wear ill-fitting shoes. The tendency to develop bunions may be present because of an inherited structural foot defect.
SymptomsBunions may or may not cause symptoms. A frequent symptom is foot pain in the involved area when walking or wearing shoes that is relieved by resting. A bunion causes enlargement of the base of the big toe and is usually associated with positioning of the big toe toward the smaller toes. This leads to intermittent or chronic pain at the base of the big toe. Bunions that cause marked pain are often associated with swelling of the soft tissues, redness, and local tenderness. It is important to note that, in post-pubertal men and post-menopausal women, pain at the base of the big toe can be caused by gout and gouty arthritis that is similar to the pain caused by bunions.
Physical examination typically reveals a prominence on the inside (medial) aspect of the forefoot. This represents the bony prominence associated with the great toe joint ( the medial aspect of the first metatarsal head). The great toe is deviated to the outside (laterally) and often rotated slightly. This produces uncovering of the joint at the base of the big toe (first metatarsophalangeal joint subluxation). In mild and moderate bunions, this joint may be repositioned back to a neutral position (reduced) on physical examination. With increased deformity or arthritic changes in the first MTP joint, this joint cannot be fully reduced. Patients may also have a callus at the base of their second toe under their second metatarsal head in the sole of the forefoot. Bunions are often associated with a long second toe.
Non Surgical Treatment
Some bunions can be treated without surgery. If you have a bunion, wear shoes that are roomy enough so that they won?t put pressure on it. You can choose to have your shoes stretched out professionally or try cushioning the painful area with protective pads. Orthotics have been shown to help prevent progression of bunions. Oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation. Applying an ice pack several times a day can also help reduce inflammation and pain. If your bunion progresses to a point where you have difficulty walking or experience pain even with accommodative shoes, surgery may be necessary.
Research shows that 85% of people who have bunion corrections are satisfied with the results. However, a number of problems can arise. The big toe is usually stiffer than before. For most people this does not matter, but for athletes or dancers it is very important. As mentioned before, the big toe is slightly weaker with a bunion, and this transfers weight onto the ball of the foot. After bunion surgery, this transfer of weight can increase. Therefore, if you have pain under the ball of the foot ("metatarsalgia") it may be worse after bunion surgery, and it may also develop for the first time. Careful surgical technique can reduce this risk, but it cannot avoid it completely. Most people who develop metatarsalgia are comfortable with a simple insole in the shoe but occasionally surgery is required. In some people the big toe slowly tilts back toward the original position and occasionally this is bad enough to need to have the operation redone. On the other hand, the toe can tilt the other way, though much more rarely. Again, occasionally this is bad enough to need to have the operation redone. Infections in the wound, plaster problems and minor damage to the nerves of the toe can occur in any foot surgery. Usually these are minor problems that get better quickly. This may sound like a lot of possible problems, but in fact most people do not get them and are satisfied with their bunion surgery. However, this may help you to see how important it is to have any bunion surgery carried out by a properly trained and experienced foot and ankle surgeon.
Make better shoe choices. If you?re a woman, avoid high-heeled footwear whenever possible (at the very least, choose shoes with heels lower than two inches), and make sure all your footwear has a wide, deep toe box. Whether man or woman, if you?re trying on shoes and your toes feel ?squished? or crowded by a particular shoe, reject that style and try another, or go for a larger size. You don?t need to invite trouble. In general, shoes that come to a point at the toe are bad news, as they tend to push the toes together into an overlapping pattern. Shoes with rocker soles will unload pressure on the bunion area. Examine your feet regularly. Note any redness, swelling or discoloration. Flex your toes and check for any stiffness. If there is any, think back to what you?ve worn or done in the past few days. If the condition persists more than a few days, or worsens, a visit to the podiatric physician is in order.
