Treatment of Recurrent Lumbar Intervertebral Disc Herniation with Target Radiofrequency Combined with Collagenase Injection

Objective To investigate the therapeutic effect of target radiofrequency combined with collagenase injection on recurrent lumbar disc herniation. Methods A total of 52 cases of recurrent lumbar disc herniation were enrolled. Different puncture paths were decided by scar tissue or herniated nucleus pulposus tissue gaps and forms. Patients received target radiofrequency with intradisc or intra-combined-extra disc collagenase injection. Patients were followed up for 6-60 months(average of 18 months),and curative efficacy was evaluated by using the Macnab criteria. Results The curative efficacy was excellent in 13 cases(25.00%),good in 25 cases(48.08%),medium in 10 cases(19.23%) and poor in 4 cases(7.69%). The efficacy rated good and above reached 73. 08%. Conclusion The intervention of collagenase injection combined with target radiofrequency is an effective treatment in recurrent lumbar disc herniation.
