SUMMARY - This study investigated the clinical value of DSA-guided combined injection of ozone and collagenase in treating lumbar disc herniation. Fifty-six patients with lumbar disc herniation were punctured post-laterally through the symptomatic side under DSA, and received intradiscal injection with 20-30 ml ozone of 60 μg/ml and transforaminal and periradicular injection with 10-20 ml ozone of 30 μg/ml. Then, epidural injections with 600 u-1200 u collagenase were made through the transsacral hiatus. All patients were followed up for one month and three months after operation, and the therapeutic outcome was best three months later. The excellent, good, fair and poor effective rates were 62.3%, 32.1%, 3.9%, 1.7%, respectively, and the excellent and good rate was 94.4%. Combined injection of ozone and collagenase under DSA guidance for the treatment of lumbar disc herniation is an effective and safe method.
