From Prof. Bertagnoli site: "The lack of control of the center of rotation is also a reason elastomer discs should not be used in segments with a spondylolisthesis (less than grade 1) or in the l5s1 spinal intervertebral disc space, which is the segment of the spine with the greatest shear force. There is simply no way for these devices to maintain stability and the patient has a higher risk of device failure."

Maybe fusion on L5-S1 is a good idea, though? Maybe at this level it is too big bone angle and it will fall apart in a dozen or so years? Maybe after 40 L5-S1 is not so mobile anymore? Maybe that's why many doctors make a hybrid if it concerns L4-S1?

It all started in 2003 with a pulsatile prick, a few cm from the center of the body at the level of L5-S1.
In 2005 1xPLDD of L5-S1
In 2005-2006 3x microdiscectomy of L5-S1.
11 years quite ok. May 2018, after lifting the weight in rotation - pain persists for a year all the time.
