Most physicians will see patients back in their office within the week and they ask you to start being active right away. We prefer you not to be bedridden or in chairs because that obviously is going to result in muscle atrophy and other complications resulting in not moving. But, I will see them a week after their procedure and then possibly a month to six weeks after that. And really, once you have the ability to see that they are doing quite well, the bone cement is not moving, there is no change in the vertebra, either at the level you worked at or surrounding it, then it’s really on an as-needed basis.
