ObjectiveTo explore the early clinical effect and safety of percutaneous transforaminal endoscopic technology for cervical spondylotic radiculopathy.MethodsFrom August 2016 to September 2017, 14 patients with cervical spondylotic radiculopathy who responded poorly to non-surgical treatment for at least 6 weeks underwent percutaneous transforaminal endoscopic discectomy via posterior approach. There were 6 males and 8 females, aging from 32 to 68 years old with an average of (40.5±7.6) years. The course of disease ranged from 0.5 to 13.0 months with an average of (6.0±1.33) months. The lesions involved C₄,₅ in 2 cases, C₅,₆ in 8 cases, C₆,₇ in 4 cases. Visual analogue scale (VAS), Japanese Orthopedic Association (JOA), Short Form 36 health survey questionnaire(SF-36) were recorded preoperatively and during the latest follow-up to evaluate the clinical outcome. Horizontal displacement and angular displacement of vertebral body were measured by cervical dynamic X-rays.ResultsAll operations were successful. No spinal cord injury, nerve root or vascular injuries were found. Operation time was from 60 to 100 min with a median of 75 min;intraoperative bleeding was from 30 to 80 ml with a median of 40 ml. All patients were followed up for 2 to 13 months with a median of 9 months. During the follow-up period, the patients with neck and shoulder pain were significantly relieved without recurrence. No nucleus pulposus protrusion was found in the primary surgical segment, and there was no obvious sign of degeneration in the adjacent vertebral body. At the latest follow-up, VAS, JOA and SF-36 scores were obviously improved(P<0.05). There was no significant difference in horizontal displacement and angular displacement of vertebral body before and after the operation (P>0.05). The cervical curvature at the latest follow-up was higher than preoperative findings (P<0.05). And there was no significant difference in intervertebral disc height preoperatively and postoperatively(P>0.05).ConclusionsPercutaneous transforaminal endoscopic discectomy in treating cervical spondylotic radiculopathy can effectively and safely relieve neck and shoulder pain, improving nerve function, enhance life quality, maintaining cervical stability. It is worthwhile to generalize and apply in clinical settings.Copyright© 2018 by the China Journal of Orthopaedics and Traumatology Press.
