spondylolysis

[nickhedonia]

Dear Christine,
re your 50 year old fellow with low back and referred pain. You mentioned spondylolysis, did you really mean this or are you referring to the more common spondylosis, if it is A, then one would expect instability leading to spondylolisthesis, with the prospect of pain dependant on the stage of this seriously unstable shifting forward event , of one vertebral body.
If instead there is spondylosis, which remember is a common phenomenon and not related necessarily to spondylolistheses or spondylolisis. Whew!, so many L's and esses. I wonder on what basis was the diagnosis made , was this by yourself or is it yet another doctor's " I don't know " couched in scientific jargon.
