The Clinical Study of the Collagenase Injection for the Treatment of Lumbar Disc Herniation / 介入放射学杂志

ABSTRACT

We injected collagenase into the lumbor disc(20 cases)or outside the lumbar disc(230 cases)for treating the patients with lumbar disc herniation from December 1994 to August 1996.200 cases had been followed up.The results were excellent or good in 91%.The authers in- troduced the operative method and its indications in detail,and suggested that chemonucleolysis is sate,good and easy to be operated with littlecomp lieation.Herniation more than 10mm in with cal- cification,lateral recess stenosis or recumance after the laminectomy are not the absolute contraindi- cations.
