Well dang it, I was almost ready to pull the trigger, now I need to do more homework. I like the LP-ESP lack of deep keels. As an engineer, I don't like stress concentrations that create a high-stress area in a critical material like a vertebrae. So I see why you wouldn't want a wedge driving against the middle of the bone for the next 30 years. And I want to start lifting again, so there's going to be a lot of force going through there. I do like the Prodisc non-elastic simple ball and socket joint. Giving up the axial degree of freedom does not bother me. I'd better go through the threads here on the devices to become better informed. Thanks again for your reply and the youtube video.

This is just my personal opinion. The Prodisc has been on the market longer than the LP-ESP but the LP-ESP was first implanted (first gen device) in 2004, so there is a decent amount of history with the device.
There are a lot of people very happy with their Prodisc. Just who knows what their adjacent vertebrae is going to look like 15-20 years after implantation. It is a gamble either way, I'm just more willing personally to gamble with the LP-ESP. And I've researched this quite a bit. |
