A bunion is an abnormal, bony bump that forms on the joint at the base of your big toe. Your big toe joint becomes enlarged, forcing the toe to crowd against your other toes. This puts pressure on your big toe joint, pushing it outward beyond the normal profile of your foot, and resulting in pain. Bunions can also occur on the joint of your little toe (bunionette). Bunions can occur for a number of reasons, but a common cause is wearing shoes that fit too tightly. They can also develop as a result of inherited structural defect, injury, stress on your foot or another medical condition.
Bunions form when the normal balance of forces exerted on the joints and tendons of your feet are disrupted. This can lead to instability in the big toe joint - also known as the first metatarsophalangeal (MTP) joint, causing a deformity. Bunions develop over years of abnormal motion and pressure on your big toe joint. They often result from a combination of your inherited foot type, faulty foot mechanics that affect the way you walk and shoes that fit improperly. Other causes of bunions include foot injuries. Deformities present at birth (congenital). Neuromuscular disorders, such as cerebral palsy or post- polio syndrome (post-poliomyelitis). Bunions may be associated with various forms of arthritis, including inflammatory or degenerative, causing the protective cartilage that covers your big toe joint to deteriorate. An occupation that puts extra stress on your feet also can be a cause. Waiters, factory workers, dancers and athletes often are more prone to developing bunions.
Signs and symptoms of a bunion include the base of the big toe is swollen and sticks out. The big toe is often bent towards the other toes, and sometimes the second toe is pushed to overlap the third toe. Skin around the big toe joint is red and sore. Thickened skin at the base of the big toe. Pain in the big toe or foot. Wearing shoes is painful. Pain or difficulty when walking.
Bunions are readily apparent, you can see the prominence at the base of the big toe or side of the foot. However, to fully evaluate your condition, the Podiatrist may arrange for x-rays to be taken to determine the degree of the deformity and assess the changes that have occurred. Because bunions are progressive, they don't go away, and will usually get worse over time. But not all cases are alike, some bunions progress more rapidly than others. There is no clear-cut way to predict how fast a bunion will get worse. The severity of the bunion and the symptoms you have will help determine what treatment is recommended for you.
Non Surgical Treatment
Bunions often respond to conservative care measures and should always be treated by a qualified healthcare professional in a timely and appropriate manner. Conservative treatment for bunions usually involves the following, splinting your great toe (so that it does not migrate toward the inside edge of your foot). A toe-spacer (such as Correct Toes) may be a useful tool, because it helps progressively splay and re-align all of your toes. Performing range of motion exercises (to move your big toe into a more favorable position). Supporting of the joints in the back of your foot that cause forefoot instability. Using shoes that allow the bunion splint to keep your big toe pointing straight ahead.
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).
