The prominent bone at the side of the big toe rubs against the shoe and the skin becomes reddened. Often a sac of fluid called a bursa may develop in the tissue overlying the prominent bone. This swelling, consisting of inflamed soft tissues and underlying prominent bone is what we call a ?bunion?. If left untreated, they can be very painful.
The causes of bunions are "multifactorial". In other words generally many things contribute to their occurence. Shoewear per se is a contributory factor but it isn't possible to say that the type of shoewear is necessairily relevant. Often there is a hereditary component with other family members also suffering with the same condition.
Just 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.
Orthopaedic surgeons diagnose bunions on the basis of physical examination and weight bearing x-rays. Two angles are assessed, the intermetatarsal angle, that is between the first and second metatarsals (the bones that lead up to the base of the toes). If this angle exceeds 9? (the angle found in the healthy foot) it is abnormal and referred to as metatarsus primus varus. the hallux valgus angle, that is, the angle of the big toe as it drifts toward the small toe. An angle that exceeds 15? is considered to be a sign of pathology.
Non Surgical Treatment
Fortunately, many bunions never go on to cause problems other than the cosmetic appearance. The easiest option is to try different shoes or padding, however this is not the answer for everyone. The various straps and braces that are commercially available are not proven to be particularly effective.
Procedures can range from shaving off excess bone to restructuring and fusing the big toe. For mild conditions, you may simply need the connective tissues holding your big toe to be tightened so they hold the digit in the correct position. More advanced bunions will need more manipulation and involved remedies. Cuts in the bone tissue can help our specialists realign the toe. You may need to have the damaged portion of the joint removed. In severe cases, the joint may be fused to prevent it from moving out of position again. If your bunion created other foot complications, like hammertoes, our specialists may correct those during the procedure as well.
If the diagnosis is made early on, such as in preadolescence, bunion development can be slowed and in some cases arrested with the proper supportive shoe gear and custom functional shoe inserts (orthotics). Avoidance of certain athletic activities with improper shoe fit and toe pressure can prevent the symptoms that occur with bunions.
