Anat Baniel's dvd's have helped me. I did have the fusion but from a surgeon who was really good st performing yhe posterior lateral interbody fusion. I understand surgeons don't like to do these as they are more tedious. Now thouhh I have chronic stiffness due to all those years of protecting my spine with stiff posture. Baniel's dvd's are what I wish I'd had thirty years sgi. My spondylolisthesis was grade 5.
