I am a 43 year old male that has had 2 Lamanectomies 1986,1998 and a 3 level Prodisc replacement in 2003. The disc replacement was and still is a success. In July 2005 I was in a horrific car accident where 20 people were injured 4 killed and. I walked after my car was hit by a run away dump truck hit on three sides and burned to the ground. After the accident I began to feel mild back pain which continued to get worse. To make a long story longer. I had a CT scan and they discovered a Pars Defect at L5/S1. I have had every shot known to man, am on pain meds and I am still in chronic pain. I had a SCS trial with the ANS and this seemed to help. The pain Management Doc is an advocate of SCS. The orthopedic surgeon that accompanied me to Germany w and assisted on the 3 Level disc replacement feels a fusion is a better option. His concern is that there is a "honeymoon" phase with the SCS and once you have built a tolerance I will may be back in the same boat as before. This is a guy that is not a slice and dice advocate for surgery, but he feels the fusion will stabilize the mechanics of L5/S1 and give me at least 50% relief which is what the pain management doc has said. I would be interested in hearing from any SCS (ANS) patients or post ADR patients (Prodisc) that have had to go under the knife again. The thought of a 4th surgery makes me ill.
