Treatment of calcified L5S1 lumbar disc herniation with percutaneous endoscopic interlaminar discectomy: A report of 15 cases and literature review / 吉林大学学报(医学版)

ABSTRACT

Objective: To investigate the clinical effect and treatment strategy of percutaneous endoscopic interlaminar discectomy (PEID) in the treatment of calcified L5S1 lumbar disc herniation. Methods: A total of 15 patients with calcified L5S1 lumbar disc herniation were selected and treated with PEID combined with variable power system. The Visual Analogue scale (VAS) and Oswestry dysfunction index (ODD scores of the patients were evaluated before operation, and Id, 1 week, 3 months, 6 months after operation. Macnab score was used to evaluate the curative effect of the patients 6 months after operation. Results: The scores of VAS and ODI of the patients Id, 1 week, 3 months, and 6 months after operation were significantly lower than those before operation (P<0. 05); the modified Macnab score showed that the excellent and good rate was 86. 67%; the postoperative image results showed that the calcification area of intervertebral disc was removed, the nerve root was decompressed effectively, and there were no nerve root injury, cerebrospinal fluid leakage and infection. Conclusion: PEID combined with variable power system can effectively treat the calcified L5S1 lumbar disc herniation with the advantages of less trauma, short operation time and short recovery period.
