hi, i have pars defect also and to make a long story short I am getting a fusion on the the 9th. I didnt know I had until after a discectomy in july. Now I am in worse pain than before. They believe the pars is the root of my problems, I hope so because I hurt but am worried and scared about fusion surgery. I have read a little about just fixing the pars fractures but I dont think its that common.
