What is Bunion?

Bunion is a foot deformity related to the great toe, often erroneously described as an enlargement of bone or tissue around the joint at the head of the big toe.

Bunions are specifically caused by the long-term use of shoes, particularly tight-fitting shoes with pointed toes. Bunions occur when pressure is applied to the side of the big toe forcing it inwards towards, and sometimes under or over, the other toes. As pressure is applied, the tissues surrounding the joint may become swollen and tender. Because bunions are, in all cases, caused by footwear they are completely unknown in cultures that do not wear shoes.

The bump itself is partly due to the swollen bursal sac and/or an osseous (bony) anomaly on the mesophalangeal joint. The larger part of the bump is a normal part of the head of the first metatarsal bone that has tilted sideways to stick out at its top.

The symptoms of bunions include irritated skin around the bunion, pain when walking, joint redness and pain, and possible shift of the big toe toward the other toes. Blisters may form more easily around the site of the bunion as well.

Bunions are mostly 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.
