目的探讨颈椎间盘突出症的微创治疗术后椎间盘内压力与临床疗效的关系。方法应用射频消融髓核成形术治疗颈椎间盘突出症47例，测定术后椎间盘内压力，观察其与临床疗效改善率的相关性。结果所有患者均在压力监测下顺利完成手术。47例患者获得1～25个月随访，根据日本骨科协会(JOA)评分法，采用术后改善率（Hirabashi公式）评定疗效。优25例，良19例，好转3例，优良率为93.6％(44/47)。术后椎间盘内压力与术后改善率有显著相关性(P＜0.05)。结论射频消融髓核成形术是治疗颈椎间盘突出症安全、有效的微创技术，术后椎间盘内压力若在3 kPa时，则效果更佳。

Objective To investigate the relationship between intervertebral disc pressure and clinical efficacy after the minimally invasive treatment of cervical disc herniation. Methods Forty-seven patients with cervical disc herniation treated by disc radiofrequency ablation, and monitored the intervertebral disc pressure after that. Moreover, the correlation between the pressure and the clinical efficacy was observed. Results All cases were successfully completed under pressure monitoring. Forty-seven cases underwent a follow-up of 1-25 months,according to JOA score,using postoperative improvement rate (Hirabashi formula) to assess the clinical efficacy. High efficacy in 25 cases,fine efficacy in 19 cases,good efficacy in 3 cases,high and fine efficacy rate was 93.6％ (44/47). The postoperative intervertebral discpressure was significantly correlated with improvement rate after cervical minimally invasive surgery (P ＜0.05). Conclusions Radiofrequency ablation treatment of cervical disc herniation is safe and effective minimally invasive technique. If the pressure in the postoperative intervertebral disc is 3 kPa,it will get better prognosis.
