Does anyone know anything about a triple fusion? Should I have a plif or alif? Meaning should they go in from the front or back. My L3 to S1 are shot. DDD real bad. I'm in pain every day for 5 years now and its getting worse. I'm set up for stem cell therapy in January where they inject 4 discs with my own stem cells as a last ditch effort to avoid a triple fusion. Has anyone heard of stem cell therapy as well? Sorry for two questions in the same post. I'm new to this.
