				        	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.
