Abstract:
Objective:To evaluate the clinical outcomes of posterior percutaneous endoscopic cervical discectomy (PPECD) for cervical disc herniation.
Methods:A total of 23 patients who underwent PPECD for cervical disc herniation at Department of Spine Surgery, Guangdong Provincial Hospital of Chinese Medicine from August 2014 to April 2016 were reviewed. The mean age of the 17 males and 6 females was 49.5 years (range from 31 to 61 years). All patients had unilateral upper limb radiating symptoms, 13 patients with right upper limb radiating pain and 10 patients with left upper limb radiation pain, 17 patients with neck pain symptoms. Responsible segment: left C4-5 1 case, right C4-5 2 cases, left C5-6 4 cases, right C5-6 8 cases, left C6-7 5 cases, right C6-7 3 example.Operating time, length of hospitalization, complications, neck and arm Visual analog scale(VAS), and Neck Disability Index(NDI) were evaluated. The excellent and good rate of surgery was evaluated by using the Odom criteria. Harrison method was used to measure cervical curvature. The Cobb angle of the surgical segment was measured on the X-ray, and the range of motion (ROM) was calculated. The changes of the cervical curvature and the surgical segment ROM were compared pre- and post-operation.
Results:The operation time was 94.1 min (range from 80 to 150 min). The average length of hospital stay was 4.8 days. The mean follow-up period was 23.5 months (range from 15 to 35 months). The preoperative arm VAS score was 6.95±0.88, 1-week postoperative arm VAS score was 2.09±0.67, the last follow-up arm VAS score was 1.04±0.98. The preoperative neck VAS score was 3.04±0.77, 1-week postoperative neck VAS score was 1.52±0.51 and the last follow-up neck VAS score was 0.61±0.78. The 1-week postoperative and last follow-up arm and neck VAS scores were significantly reduced compared with pre-operation (P<0.01). Compared with 1 week after surgery, the last follow-up of the arm and neck VAS score further reduced, the difference was statistically significant (P<0.01). The preoperative NDI was (58.52±4.98)%, the 1-week postoperative NDI was (33.74±4.72)%, the last follow-up NDI was (19.22±3.23)%. The 1-week postoperative and last follow-up NDI was significantly improved compared with pre-operation (P<0.01). Compared with 1 week after surgery, the last follow-up of the NDI further improved, the difference was statistically significant (P<0.01). The 1-week postoperative cervical curvature was (14.65±2.89)°, and it was improved compared with preoperative(14.23±3.06)°, the difference was statistically significant (P<0.05) . The last follow-up was cervical curvature(14.64±2.68)°, there was no significant difference compared with preoperative (P> 0.05). The preoperative surgical ROM was(5.37±1.83)°, 1-week postoperative was(5.53±1.52)°, and the last follow-up was (5.62±1.48)°, there was no significant difference pre-operative and post-operation (P> 0.05). The excellent and good rate was 91.3% (excellent in 16 cases, good in 5 cases, 2 cases). There was no nerve root injury, cerebrospinal fluid leakage, wound infection, and other complications.
Conclusions:PPECD is a sufficient and safe supplement for cervical disc herniation, its recent clinical efficacy was good. And it has no significant effect on cervical stability.
