Objective: To investigate the clinical effects of Posterior Percutaneous Full-Endoscopic Cervical Foraminotomy (P-PECF) for cervical osseous foraminal stenosis. Methods: A total of 11 patients of cervical osseous foraminal stenosis underwent P-PECF from Jan 2016 to Jan 2018. The Visual Analog Scale score (VAS) and Japanese Orthopedic Association Scores (JOA) were evaluated preoperative, immediate postoperatively, 1 months, 6 months and 12 months post-surgery. The excellent and good rate of surgery was evaluated by the modified Macnab criteria at the last follow-up. Results: All operations were successful. No spinal cord injury, nerve root or vascular injuries were found. The operation time was 73 min (range from 50 min to 120 min). The intraoperative bleeding was 37 mL (range from 20 mL to 50 mL). The average of hospital stay was 3.1 days (range from 2 to 7 days). All patients were followed up for 12 to 36 months. The VAS scores at immediate postoperatively and at 1, 3, 12 month postoperative were 2.91 ± 1.22, 2.27 ± 0.90, 1.64 ± 1.28, 1.27 ± 1.00 respectively, which was significantly lower than preoperative scores (7.64 ± 1.50) ( P<0.05); The JOA scores at immediate postoperatively and at 1, 3, 12 month postoperative were 12.63 ± 1.80, 15.45 ± 1.36, 16.09 ± 0.94, 16.36 ± 0.81 respectively, which was significantly higher than preoperative scores (11.82 ± 1.54) (P<0.05); According to modified Macnab criteria, 9 cases showed excellent results, 1 case showed good result, and 1 case showed fair result, with an excellent and good rate of 90.9%. Conclusion: P-PECF is a sufficient treatment for cervical osseous foraminal stenosis, and its clinical efficacy was good.
