  8. Sensory disfunction regression at 3 years Microdiscectomy Discolysis • complete 82.5 % 83.2 % • Partial 12.4 % 9.4 % • Insignificant 5.1% 2.4 % EU.N.I. www.eunionline.com

  9. Motor Deficit regression at 3 years Microdiscectomy Discolysis • complete 86.6% 85.7% • partial 9.8 % 8.3% • Insignificant 3.6% 6 % EU.N.I. www.eunionline.com

  10. Results • Complications observed in the two series of case records related to the procedure: • 4 fistulas of cerebrospinal fluid and 1 bacterial discitis in Microdiscectomy • 2 chemical discitis in Discolysis

  11. Conclusion Results are overall better for percutaneous Discolysis in contained herniations, with broken annulus, under or extraligamentosus. On the other hand, results are totally better in cases of big extruded or migrated herniations, particular if pain was intolerable or there were important motor deficits.

  12. Conclusion Microdiscectomy has a documented morbidity and mortality. A failure of Microdiscectomy is a FBSS (severe chronic postoperative pain, which is usually resistant to physiotherapy an pharmacological treatment). A Failure of Discolysis can't cause a FBSS, and rarely engenders new iatrogenic problems.

  13. Conclusion Except than these considerations results are essentially equivalent with time considering both pain control and management of neurological deficits.
