CT guided ozone injection for discogenic low back pain

Objective To explore the clinical efficacy and surgical skills of CT guided ozone injection for discogenic low back pain. Methods A total of 48 patients underwent CT guided pertacuneous 03 injection in intervertebral disc under local anaesthesia, and 20-30 mL 03 with the density of 50 mg/L was injected in intervertebral disc. The clincal efficacy was analy- sised. Results All cases were followed up for 13-25 months（average 17 months）. According to the Odom evaluation score, the clinical efficacy were rated as excellent in 32 cases, good in 9 cases, general in 5 cases, bad in 2 cases, and the rate of excellent and good outcomes was 85.4%. A part of patients got farther remission as time gone on. No nerve compromise, postoperative infection occurred. Conclusion CT guided ozone injection for discogenic low back pain has the advantages of easy operation, intuition, security, good curative effect, and avoiding X-ray radiation of medical personnel. It was a effective minimally invasive surgery for discogenic low back pain.
