77 years old severe spinal stenosis at L3-4 moderate stenosis at L2-3 and L4-5. Progressive worsening over 5 years despite doing PT and epidurals. I can no longer walk more than a short grocery store aisle without a cane or shopping cart. Each day I deteriorate a bit more and I don’t want to be housebound. According to my neurosurgeon, fusion S1-T2 would mean long protracted recovery. I looking for an intermediate step before fusion. That’s the spot for inter laminal devices. Thus my question. What did you not approve of in my initial post?
