ABSTRACT
Objective To compare medium-term therapeutic effect by bilateral and unilateral puncture plasma coblation nucleoplasty(PCN) in the lumbar disc herniation patients. Methods 90 cases confirmed no significant rupture of annulus fibrosus of lumbar disc herniation by CT or MRI were randomly divided into two groups. Bilateral and unilateral puncture plasma coblation nucleoplasty groups were respectively divided into group A and group B, and compared the JOA scores. Results 82 patients were followed up for 10 ～ 32 months,the average follow-up time was 16.2 months. Preoperative JOA scores of the two groups were not statistically significant(P ＞ 0.05) but the postoperative follow-up JOA scores were higher than preoperative(P ＜0.05) and the JOA scores of group A were higher than group B(P ＜0.05). Conclusion The medium-term therapeutic efficacy of bilateral puncture coblation nucleoplasty was superior to unilateral therpy.
