A bunion (excess or misaligned bone in the joint) is one of the most common big-toe problems, although they may develop on the fifth (little) toe. Bunions are often caused by incorrect foot mechanics. The foot may flatten too much, forcing the toe joint to move beyond normal range. In some cases, joint damage caused by arthritis or an injury produces a bunion. And some people are simply born with extra bone near a toe joint.
Over time, bone spurs (small pieces of rough or splintered bone) develop, and the joint’s range of motion becomes limited. But movement doesn’t have to cause pain. The effects of arthritis can be reduced. Talk with your doctor about developing a treatment plan to meet your needs.
Note: Arthritis is most likely to develop near the site of an old injury.
