ABSTRACT
Objective To investigate the clinical efficacy of radiofrequency surgical therapy combined with ozone for patients with discogenic low back pain. Methods The clinical data were collected in 120 patients treated with radiofrequen?cy and ozone for lumbar disc herniation at Tianjin Hospital from October 2013 to October 2015. Pain visual analogue scale (VAS) was used to patients at preoperative and postoperative 1 week, 1, 3, 6 and 12 months. Health survey (SF-36) score was used at preoperative and postoperative six months. The efficacy was evaluated by MacNab curative effect evaluation. Re?sults The preoperative VAS score was (7.02±0.64) points. The postoperative VAS scores were (3.13±0.32) points, (2.11± 0.67) points,(2.62±0.89) points,(2.37±0.34) points and (2.31±0.50) points at one week, one month, three months, six months and twelve months, respectively. The VAS scores were significantly decreased after surgery (P<0.05). Preoperative SF-36 score was (48.32 ± 7.46) points, which reached to the (82.03 ± 5.89) points six months after surgery (P < 0.05). After six months, the fineness rate reached to 89.17%evaluated by MacNab curative effect evaluation. Conclusion Radiofrequency combined with ozone treatment is an effective and reliable method for discogenic low back pain.
ABSTRACT
Objective To assess the efficacy of radiofrequency therapy combined with ozone injection in the treatment of lumbar disc protrusion. Methods A total of 202 patients with lumbar disk protrusion were included and divided into three groups:radiofrequency (RF) group, ozone (Oz) group, and combination (Co) group. The efficacy was evaluated by visual analogue scale (VAS), Macnab curative effect evaluation, and oswestry disability index (ODI) at 1d, 1m and 6m after treat?ment. Results There were no significant differences in gender, age, the course of disease, preoperative VAS scores and ODI scores (P>0.05). All patients were operated successfully. There were no infection of the intervertebral disc, no compli?cations of spinal cord, nerve and no blood vessel injury. There were no significant differences in preoperative VAS and ODI scores between three groups. The VAS and ODI scores were significantly lower at 6 month and 12 month after operation in Co group combined with those of RF group and Oz group. There were no significant differences in these two scores between RF group and Oz group (P>0.05). There were no significant differences in effective rates at 1d, 6 month and 12 month after operation between three groups (P>0.05). But the excellent and good effective rates were higher in Co group than those of RF and Oz groups. There were no significant differences in excellent and good effective rates between RF group and Oz group. Conclusion The therapy of radiofrequency combined with ozone injection is an efficient and mini-invasive tech?nique for the treatment of lumbar disc protrusion and worth promoting.
