I just had a PLIF procedure done for my S1, L5 a little more than two weeks ago. I feel I have been careful to not bend or twist as much as possible. However, I feel that I have to twist to some degree as I get out of bed or change positions. I am large chested and carry most of my weight there and have issues with trying to maintain proper alignment. My big issue is that I am very afraid of delayed or no fusion because of the pressures being put on my lower back. Am I worried about nothing...or are my fears justified. What kind of bending or twisting do they mean? At the waist?...causing a 90 degree angle? Or even slight bending to reach for something? Sorry for all of the questions...I am just worried about the success of my fusion.
