Essentially inserting a plastic brace would act to fuse those two segments together, so although it isn't a bony fusion, or a cage, it will alter the kinematics (movement) of that joint. Decompression is a specific form of traction, traction and decompression will sometimes be used interchangably, but at the root they are very different. Decompression is computerized and pull weights and vectors can be altered.
I can point you in the right direction, but I don't have the time to compile a list for you of possible providers, that's why google was invented my friend. I don't have anyone I would personally recommend in the San Diego area if that helps. Ask around, see if there are any chiropractors, MD's who have experience with decompression.
When looking for chiros, generally speaking, Active Release Technique (ART) certified docs tend to be more sports minded than your general chiropractor. http://www.activerelease.com/providerSearch.asp has a list of providers you can input to find an ART certified practitioner. At this stage in the game, at 32, with your history, wanting to do what you want to do, I think you should gather several opinions and research prior to initiating an aggressive treatment plan.
