I am a 47 yr old journeyman roofer granny. I hurt my back at work may 16th 08. And have been thru all the docs following catscan findings of spondylithesis. Lifting too much to often I guess. I am awaiting surgery which should take place in the next 3 weeks. One of my main concerns is will I need a walker or will arm type crutches be enough. I go tomm. to be fitted for a harris brace. This is to be worn approx. 3 months post-op. does anyone know what determines if the surgery is performed from the front or back? I am very worried that my career will be over. I LOVE ROOFING! And do realize that I that it will be a long recovery. But my surgeon promises that I will be able to continue in my field of work. I am wondering does anyone have any remarks on the smoking has to stop due to drastic increase in surgery failure.??????? Please let me know. I live in BC Canada.
