M96.0: Pseudarthrosis after fusion or arthrodesis

Your bones have not grown back together after an operation.

It may be that two parts of a bone should have grown together after the operation, for example. It may also be that the operation stiffened a joint. That is done, for example, when a joint is badly worn or very painful. Sometimes bones do not grow together when they are not properly aligned, for example. It may also be that the bone is inflamed or is not getting enough blood.

When bones do not grow back together, you can sometimes feel how the ends of the bones move. The affected area may not feel properly stable, and it may be painful.
