射频消融髓核成形术后颈椎间盘内压力的变化

目的 观察射频消融髓核成形术对颈椎间盘内压力的影响,以提供射频消融髓核成形术治疗颈椎间盘突出症的理论依据.方法 应用射频消融髓核成形术治疗颈椎间盘突出症患者42例(神经根型颈椎病33例,椎动脉型颈椎病9例),于射频消融前后分别测量颈椎间盘内压力,并于术后1周采用日本骨科学会(JOA)评分评估其疗效,探讨颈椎间盘内压力的变化与临床疗效之间的关系.结果 射频消融髓核成形术后,33例神经根型颈椎病患者颈椎间盘内压力较术前降低(1.84±0.96)kPa(P=0.000),术后1周JOA评分较术前升高(3.27±1.35)分(P=0.000);9例椎动脉型颈椎病患者颈椎间盘内压力较术前降低(1.72±0.92)kPa(P=0.000),术后1周JOA评分较术前升高(2.78±0.67)分(P=0.000).相关分析表明椎间盘内压力的降低程度与JOA评分的升高程度呈显著正相关(p<0.05).结论 射频消融髓核成形术可以降低颈椎间盘内压力,从而达到缓解临床症状的目的 .

Pressure changes in cervical disc after percutaneous radiofrequency nucleoplasty

Objective To study the changes of pressure in cervical disc after percutaneous radiofrequency nucleoplasty,and provide theoretical basis for percutaneous radiofrequency nucleoplasty in the treatment of cervical disc herniation. Methods Forty-two patients with cervical disc herniation (33 cases of nerve root-type cervical spondylopathy and 9 cases of vertebral artery-type cervical spondylopathy) were treated with pereutaneous radiofrequeney nucleoplasty. The pressures of operated cervical disc were measured in the operation, and their clinical effects were evaluated using the JOA values 1 week after operation. The relationship between pressure changes in cervical disc and clinical effect was studied. Results The pressure in the cervical disc in 33 cases of nerve root-type cervical spondylopathy was decreased (1.84 ± 0.96) kPa (P=0.000), and the JOA values increased (3.27 ± 1.35) scares (P=0.000) 1 week after operation. The pressure in the cervical disc in 9 cases of vertebral artery-type cervical spondylopathy was decreased (1.72 ± 0.92) kPa (P= 0.000), and the JOA values increased (2.78 ± 0.67) scores (P= 0.000) 1 week after operation. Correlative analysis showed that there was a positive correlation between the pressure decrease of cervical disc and the JOA values increase (P < 0.05). Conclusion Percutaneous radiofrequency nucleoplasty can help to reduce pressure in the cervical disc and relieve the clinical symptoms.
