Objective To evaluate the clinical effect of chemonucleolysis with collagenase and oxygen-ozone in lumbar disc herniation.Methods 90 cases with lumbar disc herniation confirmed by clinic,CT or MRI were randomly divided into the control group (collagease was injected outside the lumbar disc) and treatment group (based on the treatment of control group,oxygen-ozone was injected into lumbar disc).Results 90 cases were followed-up after the operation for 3 months.
