2020
OBJECTIVE To investigate the clinical effects of percutaneous spinal endoscopy (percutaneous endoscopy) in the treatment of high prolapse free lumbar disc herniation. METHODS From May 2016 to June 2018, 24 patients with highly prolapse free lumbar disc herniation were enrolled in this study, including 11 males and 13 females, ranging in age from 48 to 72 years old, with an average of (59.5±7.2) years old. There were 1 case of L2, 3, 5 cases of L3, 4, 18 cases of L4, 5. The course of disease ranged from 8 to 26 months, with an average of (16.2±6.3) months. All the patients were subjected to local infiltration anesthesia. The clinical outcomes were evaluated by visual analog scale (VAS) for leg pain, low backpain and Oswestry Disability Index (ODI) at preoperative, first day after operation and 6 month after surgery. All data were statisticed by SPSS 22.0. RESULTS All the patients were followed up, and the duration ranged from 12 to 24 months, with a mean of (17.5±5.3) months. The average operation time was(69.8±14.2) minutes. One patient had cerebrospinal fluid leakage, which improved after supine rest. VAS scores of lower back pain were 6.36±1.27, 3.94±1.03, 1.62±0.87, 0.44±0.27, 0.37±0.29. VAS scores of leg pain were 8.28±1.74, 3.16±1.24, 2.83±1.13, 0.83±0.31, 0.46±0.31, and the differences were statistically significant (P<0.05). The ODI were (48.79±9.83)%, (36.51±11.24)%, (21.05±6.35)%, (9.83±4.62)% and (7.24±4.72)% 1 day before and 1 weeks, 3 months, 6 months and 1 year after the operation, respectively. One year after the operation, the modified Macnab evaluation system was used to evaluate the clinical efficacy of the patients, 19 patients got an excellent result, 3 good, 2 fair and 0 poor. CONCLUSION Percutaneous endoscopic pedicle anchoring technique for the treatment of high prolapse free lumbar disc herniation can effectively improve the clinical symptoms of patients, and has the advantages of less trauma, less bleeding, rapid recovery, complete removal of the nucleus pulposus, and less pain of patients, etc., its clinical efficacy is accurate, operability is strong, it is worth promoting in the clinical use.
