Ozone combined with injection of collagenase to treat extreme lateral lumbar disc herniation

Objective To investigate the treatment efficacy of ozone combined with injection of collagenase in extreme lateral lumbar disc herniation. Methods With the C-arm monitoring,30 cases of extreme lateral lumbar disc herniation received ozone combined with ipsilateral foraminal collagenase injection. Results The postoperative telephone follow-up for 6～12 months,20 cases were excellent in the modified Macnab criteria,6 cases were good,3 cases were so-so and 1 case was poor. The improved rate was 87%,efficiency 96.6%. Conclusion Ipsilateral foraminal injection of ozone and collagenase under X-ray monitoring to treat a very prominent lateral disc can effectively lift the nucleus pulposus on nerve root compression with accurate location.
