im 48 and had three discs replaced at 38, combination of impact injuries from football but overly from heavy weights causing disc generation. Unfortunately having small joints and lighter bone structures in bodybuilding helps with the illusion of size which helps in competition well it used to, but it leaves you prone to injury, this is the issue with Ronnie he has small joints and bone structures in comparison to a lot of power lifters thats why he was the best he had a huge amount of muscle but it looked bigger due to his small joints and bone structure in comparison to say a powerlifter of similar size. But it was a catch 22 as the weight required to develop the muscle stressed the internal frame his spine. He really needs to get discs replaced not fused. But at this stage i don't even think thats going to help him much. The pain must be unbelievable, once those vertebrae start clamping nerves due to disc generation it really is torture not just the pain but the muscular atrophy that goes with it all down the nerve line. really is end of days serious training wise.
