CT guided ozone injection for the ablation treatment of cervical spondylosis / 中华放射学杂志

ABSTRACT

Objective To explore the value of CT guided ozone(O_3)injection in the ablation treatment of cervical spondylosis.Methods All 86 patients with cervical spondylosis including 37 myelopathy type,30 radiculopathy type,and 16 sympathetic type were treated with O_3 injection under CT guidance.The puncture rout was from the anteroparaline of neck to the disk.A total of (4?3)ml of O_3 with concentration 60?g/ml was injected into the disk and 10 ml of O_3 with concentration 40?g/ml was injected to the paraspinal tissue.Results After injection CT scan showed that O_3 was distributed within the disk and the protruding part as low-density air shadow in 37 myelopathy type and 30 radieulopathy type patients.O_3 was observed to spread in the anterior epidural space of spinal canal and the paraspinal tissue.Three months after 03 injection,67 patients (78% )showed excellent clinical efficacy,14 (16% )had good clinical efficacy,and 5 (6%)were poor respectively.Conclusion CT guided O_3 injection is an accurate,safe, and effective method in the treatment of cervical spondylosis.
