A bunion is a firm, fluid-filled pad overlying the inside of the joint at the base of the big toe (metatarsophalangeal joint). The pad (bursa), which may get larger and stick out, can become inflamed and painful. Bunions may run in families, but many result from wearing tight shoes. Nine out of 10 bunions are developed by women. Nine out of 10 women wear shoes that are too small. Tight shoes also can cause other disabling foot problems like corns, calluses and hammertoes.
Women tend to get bunions more than men. This could be due to the more restrictive footwear they wear, (such as high heels or narrow toe boxes which force the big toe towards the little toes) but women also tend to have looser ligaments, making them slightly more prone. You?re also more likely to get bunions if your parents or grandparents have them.
The major symptom of bunions is a hard bump on the outside edge of the foot or at the base of the big toe. Redness, pain and swelling surrounding or at the MTP joint can also occur.
Before examining your foot, the doctor will ask you about the types of shoes you wear and how often you wear them. He or she also will ask if anyone else in your family has had bunions or if you have had any previous injury to the foot. In most cases, your doctor can diagnose a bunion just by examining your foot. During this exam, you will be asked to move your big toe up and down to see if you can move it as much as you should be able to. The doctor also will look for signs of redness and swelling and ask if the area is painful. Your doctor may want to order X-rays of the foot to check for other causes of pain, to determine whether there is significant arthritis and to see if the bones are aligned properly.
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.
For very severe bunion deformities where there is considerable angulation between the first and second metatarsals an osteotomy of the metatarsal may not be sufficient and for these patients, the joint between the first metatarsal and the cuneiform bone is fused with screws, called the Lapidus procedure. This realigns the metatarsal completely and stabilizes the bone, preventing mobility and recurrent deformity.
