My question,( because I can't see my doctor for 6 weeks)is: Does "no secure osseous fusion seen st L4-L5" mean what I think it means? I had a repeat lumbar fusion 15 months ago(because the first one failed)at L4-L5. Over the past 6 months my pain has increased with the typical pain and radiculopathy in buttock, thigh, calf and foot returning. Had a CAT scan yesterday and the report came back saying that "no secure osseous fusion seen at L4-L5 level although there are bone chips and ossifications in the soft tissues around the posterior elements". I can't get in to see either my surgeon or my GP for 6 weeks and wondered if anyone had an idea of what this means. I interpret it, (especially with the increase in pain)as meaning that the fusion that was done at L4-L5 did not take...fuse properly? or completely? or at all. My first fusion at this level failed, according to my doctor, because the bone they put in reabsorbed. There was no instrumentation with the fusion. I have never posted on a forum so I hope I didn't make this too long.
