| ABSTRACT Objective: To investigate the early clinical efficacy and safety of percutaneous transforaminal posterior approach in the treatment of cervical spondylotic radiculopathy (CSR). Methods: from August 2016 to September 2017, 14 patients with CSR were treated. There were 6 males and 8 females. The age was 32~68 years (average 40.5 years), and the course of disease was 0.5 to 13 months. It involved segment: 2 cases of C4/5 segment, 8 cases of C5/6 segment, and 4 cases of C6/7 segment. All patients were treated with nonoperative treatment for more than 6 weeks, and the curative effect was not good. All patients underwent posterior percutaneous transforaminal endoscopic discectomy Jingquan treatment. Determination of visual analogue scale neck and shoulder pain patients before and at the last follow-up (visual analogue, scale, VAS) score, Japan (Japa-nese Orthopaedic Association, Department of orthopedics Institute JOA) concise health status score, cervical vertebra disease questionnaire (Short Form 36 health survey questionnaire, SF36) displacement score and horizontal displacement of vertebral body and the vertebral angle, and recorded during the treatment and follow-up of complications. Results: all patients completed the operation successfully without spinal cord or nerve root injury. The operative time was 60 to 100min, median 75min, and the bleeding time was 30 to 80ml, median 40ml. 14 patients were followed up for a period of 2~13 months, with a median of 9 months. During the follow-up period of patients with neck and shoulder pain were significantly relieved and no recurrence, the primary surgical segment no re herniated, no obvious signs of degeneration of adjacent vertebral bodies. Compared with the preoperative, the last follow-up of patients with neck pain VAS score decreased significantly, (6.52 + 2.01), (1.22 + 0.74), t=9.23, P= 0, JOA score and SF score were significantly increased to 36 (12.48 + 1.31), (16.32 + 0.69), t=9.736 P=0.000; and (61.5 + 14.2), (79.2 + 16.5), t=3.006, P=0.006; compared with the displacement of horizontal displacement of vertebral body and anterior vertebral angle, there were no significant differences in (1.13 + 0.62) mm, (1.17 + 0.37) mm, t=0.204, P=0.891; (4.97 + 1.33). (5.06 + 1.14), t=0.171, P=0.866. At the end of the follow-up, patients with cervical curvature was significantly higher than that before treatment, the difference was statistically significant, (11.23 + 0.99), (7.75 + 0.79), t=10.280, P= 0, slightly lower than the height of intervertebral disc lesions before treatment, the difference was not statistically significant, (5.52 + 0.6), (5.65 + 0.5) points t=0.623, P=, 0.539. Conclusion: percutaneous transforaminal endoscopic posterior discectomy can effectively relieve patients with single segmental CSR neck and shoulder pain symptoms, improve neurological function, improve the quality of life of patients, but does not affect the stability of the spine, high safety, worthy of clinical application. |
