My dad is 82 years old and seriously considering back fusion and laminectomy surgery for his L-3/L-4 after having the same surgery 8 years ago for L4/L-5. Since he did ok with that surgery, he thinks this will be the same. Unfortunately, since then he has developed Parkinson's and of course is much weaker and older. He has only had 1 cortisone injection which did very little good so he is ready to jump right in to surgery. At his age, the complications from surgery and a smooth recovery are very concerning to me as his oldest daughter and primary care giver after surgery. Am I just being over protective or is there some real merit to my fears?
