Protrusions or enlargements of the big toe joint on the inner side of the foot are the most common type. The big toe is directed sideways toward the second and causes the foot to be wider across the metatarsal. The first metatarsal protrudes out of the middle of the foot and the joints, muscles, and tendons become displaced and strained. The following types of bunion deformities are seen:
- Hallux Valgus
Articulation of the great toe joint becomes distorted causing unequal weight bearing of the foot and gait abnormalities.
- Tailors Bunion
Similar to hallux valgus except occurring on the fifth metatarsal.
- Hallux Rigidus
The protrusion of the first metatarsal joint occurs at the top of the foot. Often the joint has chips and spurs and cannot move.
