I'm a 41 year old male Police Officer in relatively health condition. While working I re-herniated a disc during a physical altercation with an arrestee in which my neck was hyper extended by considerable force. After months of rehab and 3 injections I ended up getting a Prodisc-C implanted at C4-C5 due to that injury. The Doctor says that I have mild DDD and that my C5-C6 disc is not so healthy. My concern is that over the past 10 years I've had 5-7 incidents during arrests, fights and training incidents that have aggravated my herniated disc, sometimes for days other times for weeks. I'm can't seem to get a straight answer from my Doc on the consequences of another injury such as the one I suffered, causing the need for this surgery. I've been searching the internet for answers but have come up with little to no info. I have two young children under 4 years and I'm afraid of becoming disabled due to another injury in my neck. I have considered retiring on disability but I don't want to if there is little to no chance of failure of the Prodisc or surrounding discs. The only thing the doc would say is that he can't promise or guarantee it won't dislodge or cause the adjacent disc to rupture. He said it would take a strong impact to do so. He did recommend transferring to a less physically demanding position within the PD. Unfortunately I work for a small department where the only options are patrol, investigations or promotion to management. I'm currently in patrol and investigations and promotion are years out of reach. So I would really appreciate any advice from people with similar circumstances or with knowledge of positive/negative results due to prodisc-c implants.
