•Axial low back pain of presumed discogenic origin of at least 6 months duration and non responsive to treatment of at least 6 months conservative medical management.
•History consistent with discogenic low back pain ( e.g. predominant axial pain produced on lumbar motion, significant functional limitation in sitting duration and tolerance) A neurological exam without marked motor deficit. Age between18 and 65 years and painintensity should be NRS 5 or higher. In discography Todd Wetzel classification grade 2 and 3 and a provoked pain of at least NRS 5
•Are the trial subjects under 18? no
•Number of subjects for this age range:
•F.1.2 Adults (18-64 years) yes
•F.1.2.1 Number of subjects for this age range
•F.1.3 Elderly (>=65 years) no
•F.1.3.1 Number of subjects for this age range

•Severe disc degeneration at the affected level as evidenced by >50% disc height loss on plain anteroposterior and lateral lumbar radiographs or CT/MRI.
•- Extruded or sequestered herniated nucleus pulposus at the affected level(s).
•- Body Mass Index BMI of = 35
•- Weighted pain with NRS below 5
•- Previous lumbar back surgery ( e.g. Laminectomy, discectomy or fusion)
•- Invasive intradiscal procedure previously performed at the same level.
•- Moderate to severe spinal stenosis due to osteophyte and/or ligamentous overgrowth as evidenced by MRI or CT, provided stenosis is the cause of pain.
•- Moderate to severe endplate degenerative changes at the affected levels
•- Grate 1-2 spondylolisthesis
•- Pregnancy
•- Coagulopathy or oral anti-coagulant therapy
•- Infection
•- Patients incapable of following verbal or written instructions or with psychiatric problems potentially interfering with cooperation in the study
•- Discography: Appendix 1.
•That shows a posterior annular disruption to extend into the outer annulus or beyond the confines of the outer annulus.
•Discography without pain reproduction at the affected level( s), or with discordant pain at adjacent unaffected levels at up to 50 Psi above opening pressure.
•Pain provocation in disc at pressures >50 Psi above opening pressure
•Todd Wetzel classification grade 1, 4 and 5.
