A bunion deformity is made up of three parts. The physician or doctor will analyze your foot during the medical consultation and point to you which part, if there is any or the entire parts your bunion deformity has.
- Increase in the size of the metatarsal head, which causes bumps on that part of the foot.
- Deviation of the first metatarsal bone toward the midline of the body which causes the metatarsal head to protrude and therefore makes the bump more visible.
- The big toe moves toward the little toe and pushes against the second toe.
