Key Questions (KQ)

Questions on Surgery (KQ 1-4)

    In adults with symptomatic, stable degenerative lumbar 
spondylolisthesis (DLS) with or without radiculopathy or neurogenic 
claudication
     Key Question 1. What are the benefits and harms of surgery 
with instrumentation in addition to decompression compared with 
decompression alone?
    In symptomatic adults with unstable or stable DLS with or without 
radiculopathy or neurogenic claudication undergoing instrumented 
fusion:
     Key Question 2. What are the benefits and harms of the 
addition of an interbody cage to instrumentation (e.g., pedicle screws) 
compared to use of instrumentation alone (i.e., posterolateral fusion)?
     Key Question 3. What are the benefits and harms of the use 
of bone graft extenders and biologic substitutes compared to the use of 
autografts?
    In adults with symptomatic, degenerative lumbar spine disease 
undergoing instrumented fusion:
     Key Question 4. Does the use of intraoperative monitoring 
(IONM) decrease perioperative neurological injuries compared with not 
using IONM?

KQ 5 and 6: Questions on Non-Surgical Procedures for Chronic Low Back 
Pain Due To Degenerative Spine Disease

    Key Question 5. In adult patients with chronic low-back pain (>=3 
months) resulting from degenerative disease what are the benefits and 
harms of lumbar epidural steroid injections, intra-articular (facet) 
injection, medial branch blocks, or radio frequency ablation?
    Key Question 6. In adult patients with chronic low-back pain (>=3 
months) resulting from degenerative disease of the lumbar spine, does 
symptomatic improvement to therapeutic challenge with lumbar epidural 
steroid injections, intra-articular (facet) injection, medial branch 
blocks or radio frequency ablation predict positive outcomes after 
lumbar fusion surgery?
    Special populations and factors for Key Questions 5 and 6: Age, 
sex, BMI, presence of psychological comorbidities, presence of medical 
comorbidities, baseline pain severity, presence and type of concomitant 
degenerative lumbar spine disease, presence and severity of DLS.
