One thing to keep in mind as well is that although there is risk involved; that risk is very low. Your body is doing what it would have already done in the event of an accidental broken bone, anyway and broken bones happen and heal up just fine every day. Of course, the difference here is that the bone break is controlled, clean, and precise. Imagine that most broken bones are sudden and shocking and also result in terrible muscle tears and damage. Unplanned, accidentally broken bones are much more cause of concern than a well-planned and precise break. Another difference is that your muscles are being forced to grow right along with your bone. Having said this, as long as you do not lengthen beyond your body's capacity; there isn't much risk to be concerned about. Generally, the body recovers extremely well. I have only heard of very few stories that something has gone wrong in CLL and usually, it involves negligence on the part of unprofessional doctors or careless patients. You also do have the occasional random situation where a person's body is not recovering well (Non-Union, etc). Most complications have solutions, but even the complications are rare.
If I would have become disabled, I would have accepted it and become the best man I could be but this time, I'd have to do that in a wheelchair.
Keeping fighting the good fight.
All the best,
