Abstract:
Objective To evaluate the therapeutic effect of collagenase chemolysis after 1,2,3 years and analyse the relationship between the therapeutic effect and image features. Probing the image features for the indication, 1 254 patients with integral data who received collagenase chemolysis procedure were followed. Methods According to standard unification diagnostic criteria and therapeutic method, 1 254 patients with lumbar intervertebral disc herniation who had intergral data and received collagenase chemolysis from January 1996 to January 1999 in our department were followed up (by visit, letter or telephone call etc). The therapeutic effects of collagenase chemolysis after 1,2,3 years were evaluated with unified therapeutic effect criteria. Results For the simple lumbar intervertebral disc herniation, 1 year effective rate was 93.1%, 2 year effective rate 90.3% and 3 year effective rate 90.9%. Conclusions The simple lumbar intervertebral disc herniation is the absolute indication of collagenase chemolysis, but those combined with other factors dosen't adapt to collagenase chemolysis.
