A bunion on top of the foot is not typically hereditary, but often starts because of trauma. A sprain or jamming of the great toe joint causes a progressive buildup of bone, or bone spur, on top of the joint. As this continues, it further restricts the joint and the pain increases.
Early detection of a dorsal bunion can be treated with a custom orthotic. A thin carbon steel liner is also helpful to restrict motion to reduce pain. With this type of bunion, however, surgery may be needed to remove the bone spur and restore joint motion. Your Houston podiatrist will provide the most comprehensive recommendation for you.
