Several techniques of minimal invasive spinal surgery are now becoming common roles in the treatment of spinal diseases in many spinal centers. In the present report, the authors present a retrospective, cohort evaluation of 46 consecutive patients who underwent full endoscopic lumbar discectomy. The purpose of the present report was to present outcomes in this initial series of patients and to present outlines of the operative technique; the full endoscopic uniportal lumbar discectomy. The present research is the first preliminary report in Thailand to analyze and evaluate this new surgical technique.


Forty-six lumbar disc herniation operations were performed in two spinal centers between February and June 2008, using the full endoscopic uniportal with Vertebris instrumentation system. The operations were carried out by interlaminar and transforaminal approach using an 8 mm-diameter uniportal endoscopy of Vertebris instrumentation. The outcome was clinically assessed, on immediate post-operation and one month after surgery, by using Visual Analogue Scale (VAS), the Thai Version of the modified Oswestry disability index (ODI) questionnaire (version 1.0), and modified McNab criteria.


Excellent and good outcome was achieved in 87.4% of patients from Modified McNab criteria. Forty-three patients (93.5%) had significant improvement of sciatic pain immediately after the operation. Eight postoperative complications were demonstrated and discussed.


Full endoscopic uniportal lumbar discectomy is a novel and effective minimally invasive spinal surgical technique. However, the technique requires surgical skill training and experience.
