Radiofrequency thermal annuloplasty in the treatment of discogenic low back pain

Objective To investigate the short-term outcome of radiofrequency thermal annuloplasty in the treatment of discogenic low back pain. Methods 65 cases with discogenic low back pain were treated with radiofrequency thermal anuloplasty from Oct. 2010 to Oct. 2012. Results All cases were followed-up for 12 months. The preoperative VAS score was（6.24±0.97）,VAS scores of postoperative 7 d,1 month,6 months and 12 months were（2.49±0.81）,（2.33±0.70）,（2.42±0.67）,（2.38±0.82）,respectively,which decreased significantly compared with preoperative VAS（P〈0.01）.There were no significant differences in VAS score among postoperative 7 days,6 months and 12 months. There were 29 cases in excellent,good in 31 cases,fair in 5 cases according to Mac Nab score system. The total effective rate was 100%,and the excellent and good rate was 92%. Conclusion Radiofrequency thermal annuloplasty is an effective,minimally invasive treatment for discogenic low back pain.
