Thank you very much for your reply.
I am scheduled to have facet joint blocks and si joint blocks at my pain clinic. I have had a second opinion and he too could not understand the cause of my symptoms.
I do remember both surgeons mentioning I have no pars defect on my CT scan, which based on my research is the main reason for having isthmic spondylolisthesis. Could something such as a pars defect be missed on a CT scan? Or is there other reasons which by a person could get isthmic spondylolisthesis? And could other scans be helpful in determining such issues?
Kind regards
Joe
