Had three spinal surgeries, two laminectomies that both failed quickly, and finally a two level PLIF at the L4-L5 and L5-S1 levels, in 2004. The surgery released the nerves for the right leg and its paralysis ended. Back at work from the PLIF surgery in 4 weeks, wore a fitted and formed brace for 6 weeks. Returned to racing motocross in 6 months. No problems with cycling at all, from the spinal injury and subsequent surgeries. Not related to all the abdominal surgeries, or the Kidney Disease and Parkinson's Disease, I have.
