bunion etiology
The exact cause of bunions is not fully understood, but there are several factors that may contribute to their development. Some of the most common causes include:
-
Genetics: Bunions tend to run in families and people who have a family history of bunions are more likely to develop them.
-
Foot mechanics: People with flat feet or those who overpronate (roll their feet inward) are more likely to develop bunions. This is because the foot's natural mechanics are altered, causing the big toe to move towards the second toe, which can lead to the development of a bunion.
-
Trauma: Trauma to the big toe joint, such as a break or sprain, can cause the bones to shift and lead to the development of a bunion.
-
Rheumatoid arthritis: People with rheumatoid arthritis are more likely to develop bunions due to the inflammation and damage to the joints.
-
Ill-fitting shoes: Wearing high heels, tight shoes or shoes that are too narrow can put pressure on the big toe joint and lead to the development of a bunion.
It's important to note that bunions can develop over time, and it's not always clear what causes them. Additionally, a combination of factors may be involved in the development of a bunion, and it's not always possible to prevent them.
