A bunion is a deformity causing the great toe to deviate laterally, involving multiple joint pathologies. It restricts movement, may lead to arthritis, and can result from genetics or improper footwear.
Various characteristics and causes can include:
- Lateral deviation of the hallux (great toe) toward the second digit
- Involves multiple pathologies of the first metatarsophalangeal joint
- Enlargement of the medial (inner) first metatarsal head
- Restricted range of motion
- Progressive lateral deviation, potentially leading to arthritic changes
- Can be genetic or caused by faulty mechanics
- Often associated with chronic use of high-heeled or ill-fitting footwear
