Objective To analyze the clinical efficacy of spinal endoscopic technique for extremelateral lumbar disc herniation. Methods Thirty-two patients with extreme lateral disc herniation treated bypercutaneous endoscopic spine surgery were collected. The patients were assessed by visual analogue scale(VAS) score and Oswestry disability index(ODI) at 1st day, 1st week, 3rd month and 6th month. TheMacnab criteria were used to evaluate the clinical efficacy. Results There were no complications such asvascular nerve injury. The operation time of single section was 20 min(10-35 min), the hospital stay was 5days(3-7 days). During the follow-up periods of 1 day, 1 week, 3 months, and 6 months post-surgery, theVAS scores were 2.53±0.61, 1.50±0.43, 1.48±0.35, and 1.47±0.31 respectively, significantly lower than be-fore surgery(8.81±0.42, all P0.05). The ODI at 1st day, 1st week, 3rd month, and 6th month post-surgerywere(18.01±6.42)%,(17.54±5.53)%,(16.33±6.42)%, and(16.04±6.51)% respectively, significantly lowerthan before surgery [(76.51 ± 13.25)%, all P0.05]. Excellent and good rate was 93.75% according toMacnab(19 in excellent, 9 in good, and 2 in fair). Conclusion Percutaneous endoscopic technique via thespinal lateral approach for extreme lateral lumbar disc herniation has the advantages of shorter operativetime, less trauma, quicker recovery and better curative effectiveness.
