Abstract:
Objective To study the short-term outcome of transforaminal posterolateral endoscopic discectomy and radiofrequency annuloplasty in patients with discogenic low back pain. Methods A total of 25 patients with discogenic low back pain,who were diagnosed by provocative discography,received transforaminal posterolateral endoscopic discectomy and radiofrequency annuloplasty in our hospital. The VAS scores determined before and 6 months after the operation were compared in the patients. Their MacNab scores were also evaluated at 6 months postoperation. Results After the surgery,2 patients who had ruptured intervertebral discs (L5-S1) developed sunburn syndrome,and then was relieved by pulsed electrical stimulation for one week. The patients were followed up for 6-10 months,during which no other postoperative complications occurred. The mean VAS score of this series decreased significantly after the treatment,and kept being reduced in 6 months [preoperation:6.24?0.97,1,3,6 months after the operation:0(0~2); Kruskal-Wallis rank-sum test,H=61.680,P=0.000]. Four patients showed lower limbs pain before the treatment and were relieved after the surgery. The evaluation of MacNab score showed excellent in 11 pateints,good in 12,and fair in 2,suggesting an effective rate of 92.0%(23/25). Conclusions Transforaminal posterolateral endoscopic discectomy plus radiofrequency annuloplasty is effective for discogenic low back pain in a short term.
