Abstract: Objective To observe the clinical effect of medical ozone water point injection combined with cervical traction on the treatment of cervical spondylosis of vertebral artery type. Methods A total of 70 patients were randomly divided into treatment group and control group, 35 cases in each group. The treatment group was treated by acupoint injection of medical ozone water combined with cervical traction, while the control group was treated by cervical traction. The acupoint injection of medical ozone water was given every other day; the cervical traction was given once a day, 15-20 minutes each time; two weeks was a course of treatment. Before and after treatment, the scores of symptoms and signs, and the curative effect index were used to evaluate, respectively. Mean blood flow velocity(Vm) of bilateral vertebral artery(VA), basilar artery(BA) and bilateral posterior cerebral artery(PCA) were measured by transcranial Doppler(TCD), and then analyzed and evaluated. Results Compared with the control group, the treatment group(cure and effective) rate was 91.43% and the total effective rate was 100% better than the control group(all P<0.05). There was no significant difference in the scores of symptoms and signs between the two groups before treatment(all P>0.05). Compared with the same group, the scores of symptoms and signs in both groups were improved after treatment(all P<0.05), and the treatment group was better than the control group(all P<0.05). There was no significant difference in Vm of VA, PCA and BA between the two groups before treatment(all P>0.05). Compared with the same group, the Vm of VA, PCA and BA in both groups increased significantly after treatment(all P<0.05), and the treatment group was better than the control group(all P<0.05). Conclusion The technique of "medical ozone water point injection combined with cervical traction" is effective in treating CSA. It can improve the blood flow velocity of patients with bilateral VA, bilateral PCA and BA.
