How did I develop arthritis in my wrist?

Many wrist injuries, such as fractures and sprains, heal fairly easily. However, they can lead to problems much later in life. The injury changes the anatomy of the wrist just enough so that the parts no longer work smoothly together. The changes from the injury cause a lot of wear and tear on the wrist joint. Over time, this wear and tear degenerates the tissues of the joint, leading to wrist osteoarthritis. Doctors may also call this type of degeneration post-traumatic arthritis.
