Clinical application of anterior percutaneous endoscopic cervical discectomy / 中华创伤杂志

ABSTRACT

Objective To evaluate the safety,feasibility,and clinical outcome of anterior percutaneous endoscopic cervical discectomy (PECD).Methods The study involved 28 patients undergone PECD.Visual analogue scale (VAS) and MacNab scale were recorded before operation and at 3 days,1,3,6,12 and 18 months after operation.In addition,MRI examination was conducted at postoperative l month,3 months and 12 months.After data collection,single-factor T test with SAS software was performed.Results Follow-up (range,18-24 months,mean 19 months) was achieved in 25 patients.When compared to the preoperative score,VAS and MacNab scale presented improvement at postoperative 3 days (P ＞ 0.05) and great improvement at postoperative 1,3,6,12,18 and 24 months (P ＜ 0.01).VAS and MacNab scale at postoperative 3 days presented statistical differences as compared to those at postoperative 3,6,12 and 18 months (P ＜0.05),but the differences were not statistically insignificant at postoperative 3,6,12,and 18 months (P ＞ 0.05).Moreover,VAS and MacNab scale showed significant improvement at postoperative 24 months as compared to those before operation (P ＜0.01) and those at postoperative day 3 (P ＜ 0.01).Conclusion Anterior PECD is effective in treatment of cervical soft or partial hard disc herniation.
