What Is a Bunion?
Bunions, also known as a “hallux valgus deformity” is a condition that causes the big toe of the foot to point towards the other toes.
The first tarsal-metatarsal (TMT) joint is an important joint in the inner part of the middle of the foot.
When this joint has too much looseness or movement, the condition is known as hypermobility or instability.
When this joint becomes hypermobile, the first metatarsal moves too much in one direction and the first toe compensates by moving too much in the other direction.
When this happens, a bunion develops. Bunions usually occur slowly.
As the deformity increases it may make it painful to walk or wear shoes.
Bone spurs may also form in the joint of the big toe and cause pain when walking or bearing weight.
This condition is more common in women. It often affects women who wear tight shoes or high heels, but this condition can also be caused by repetitive actions with improper balance such as running or sports.
Deformities in the foot or arthritis have also been known to cause bunions.
