I have just found this site as I have had a lamnectomy in April 2008 and have just found out I need some 'scaffolding' put into my spine too as it has become unstable. :jawdrop:
It was great after the op - but after about 12 weeks - my back has 'got stuck' making it difficult to walk very far. I walk with my bottom sticking out! Lol!
Would be interested in hearing from anyone who has simular problems!
