Background:
This study aimed to explore the clinical values of the percutaneous spinal endoscopy "isolation zone" technique for discogenic low back pain (DLBP).
Methods:
This retrospective case series study enrolled patients with intervertebral DLBP treated with the percutaneous spinal endoscopy "isolation zone" technique in the department of Orthopedics, Cangzhou central Hospital affiliated to TianJin Medical University between September 2017 and September 2020.
Results:
Forty-five patients with DLBP were enrolled. The mean operation time was 94.7 ± 17.7 min. The visual analogue scale (VAS) score of lumbosacral pain was 6.95 ± 1.02 before operation, 2.64 ± 0.71, 1.80 ± 0.54, 1.42 ± 0.50, and 1.27 ± 0.45 at 1, 3, 6, and 12 months after operation, respectively. The Oswestry disability index (ODI) score of low back pain was 72.84 ± 5.95 before operation, 35.1 ± 5.30, 25.22 ± 4.85, 16.78 ± 4.63, and 10.91 ± 2.36 at 1, 3, 6, and 12 months after operation, respectively. At final follow-up, the treatment effect based on modified MacNab criteria was excellent in 24 cases, good in 13 cases, and fair in 8 cases. The excellent/good rate was 82.2%.
Conclusion:
The percutaneous spinal endoscopic "isolation zone" technique seems to be a promising surgical alternative for DLBP.
