I was wandering if anyone has had this operation done. My partner has Chronic L5 Radiopathy and has been suggested to have the above surgery. I have been reading that once a fusion has been done it creates preasure on the above disc and also once a disc has been replaced it can not be fused if problems occur later in life. My question is if anyone has had a disc replacement on the L5-S1 instead of a fusion? 1 surgeon said that his L4-5 Disc was pristine and 1 surgeon has recommended replacing as the fusion puts additional preasure and the disc on L4-5 has slight oesteoathritis but nerves etc all look good. If anyone has any advice or experience please share as we want to get as much info as possible before making final decision and we are also getting 2 more opinions.
