Anterior Percutaneous Cervical Discectomy. Two-Year Follow-Up of a Blunt Technique Procedure

Abstract

Objective: To report the outcomes of non-endoscopic percutaneous cervical discectomy by anterior blunt approach for the treatment of degenerative disc disease. Methods: A review of the medical records of patients with axial cervical pain resulting from degenerative disc disease and treated with discectomy and percutaneous nucleoplasty by anterior blunt approach with radiofrequency source was carried out. The data were evaluated according to modified MacNab and pre-and postoperative VAS criteria at 3, 12 and 24 months. Results: Sixty-two procedures were performed in 48 patients between 2008 and 2014. The mean age of the population was 52.4 years. MacNab results were 84.6%, 92.3%, and 89.2% improvement (excellent and good results) at 3, 12 and 24 months, respectively. The VAS changed from 7.4 to 2.3 two years after the procedure, showing a statistically significant difference (p=0.000). There were no major complications or re-interventions related to the technique. Conclusions: Anterior non-endoscopic discectomy and nucleoplasty for the treatment of discogenic axial cervical pain may be an effective alternative to open surgery. In the two-year follow-up, our blunt technique proved to be a safe procedure with no approach-related complications, and provided outcomes comparable to those reported using the original needle technique.Keywords: Spine; Intervertebral disc degeneration; Neck pain; Diskectomy, percutaneous; Minimally invasive surgical procedures.
