Well I can relate to your problem. However, if your surgeon is telling you that an ALIF (anterior interbody lumbar fusion) is minimally invasive, in my opinion, they are not telling you the truth. I pretty much have the same problem as you. If you type in ALIF in the search box, you'll see my post. As far as an ALIF procedure, according to what my surgeon has told me, it looks to be pretty invasive! LOL LOL My procedure (if I choose to go through with it LOL ) will not have any cages per se. I can't remember exactly what he called the thing they will be using, but it wasn't titanium cages. As far as range of motion, according to my surgeon, since it is so low on the spine, no noticeable loss will be noticed. I too have a pretty demanding job, and one of my main hobbies is racing and I can't be limited in motion when I need to be bent over the race car!! LOL LOL But I wish you the best of luck with what ever you decide to do and re-post and let us know how it went. Oh, I would recommend that you talk to as many people as possible and attend any seminars on back pain/surgery available in you area to gain as much information and insight before you proceed. There are more back surgeries preformed in this country than any other in the world and the reason is (in my opinion) because there is NO Guarantee as to the outcome and there is BIG money in it!!
