Abstract:
Objective To investigate the technique and effectiveness of CT-guided collagenase injection into prominence of herniated lumbar disc and the surface of prominence in the treatment of lumbar disc herniation. Methods One hundred and fifty-five patients with lumbar disc herniation diagnosed by clinic and CT received CT-guided collagenase injection, with the approaches via intervertebral foramen in L3-4 and L4-5, and the approaches via margo medialis of joint processus articularis in L5-S1. Results Injection was done successfully in all patients (100%), the clinical rate of excellent and good results were 94.2%. The herniation disappeared or significantly reduced as demonstrated by CT scan in 32 of 34 patients (94.1%), the rate of excellent and good results were 100%. No changes existed in 2 cases. There were 2 cases of disc inflammation in our group. Conclusions CT-guided collagenase injection into the prominence of herniated lumbar disc and its surface is a safe and efficient method in the treatment of herniated lumbar disc.
