Abstract: 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.
