I had a facet block done at L5-S1 and L4-L5 about 8 months after surgery on my left side with no pain relief. Is it possible this fracture was reopened when both levels were distracted, this causing continued pain? My pain is very localized, surely it can’t be coincidence the pain is in the area of the pars defect? Could the bones have healed without being lined up properly, which is causing pain in the area due to improper alignment along the pars interarticulis? Even if the fracture itself is not a pain generator, couldn’t it heal incorrectly and cause ligaments and or tendons to cause pain? My MRI’s never showed arthritic facets before or after surgery. It just seems too conincidental that the localized pain i have on my left side just happens to be the general location of the pars fracture. I can put one finger on my left side and put it right on the spot of chronic pain. Can’t a CT scan evaluate that fracture and access whether it’s causing anything connectedr above and below it to not function correctly? I read a previous post that you did not like anterior fusions for pars defects because you believe they should be supported from the posterior. Wouldn’t cleaning out the break and aligning it, setting it with a screw and letting it fuse restore that posterior support? Couldn’t fixing that pars defect indirectly influence the functionality of everything in the area?
