Now here is a question, prompted from another post.
Do spondys have a one or two level fusion??
I had S1/L5 done then year later had L5/L4.
Is this normal? Do they need to secure the whole segment?
I have read about securing the slip level but how do you know which one it is...in my case L5 vertebra slipped. So S1 and L4 were "off"....
