Abstract:
Objective To investigate the efficacy of percutaneous laser disc decompression(PLDD)combined with injection of collagenase through a target location for treatment of lumbar intervertebral disc protrusion.Methods Ninety patients with lumbar intervertebral disc protrusion scheduled for discolysis,aged 31-52 yr,weighing 58-70 kg,were randomly divided into 3 groups: PLDD group(group P,n = 29),collagenase injection group(group C,n = 31),PLDD combined with injection of collagenase through a target location group(group PC,n = 30).The puncture was performed under the guidance of CT.Group P was treated using PLDD.Group C was treated with collagenase injection.Group PC was treated with injection of collagenase after PLDD was completed.The therapeutic effect was assessed before operation and on day 7,30,60 and 90 after operation using M-JOA score.Results M-JOA grade was significantly higher at the each time point after operation in group P and PC,and on day 30,60 and 90 after operation in group C than that before operation(P ＜ 0.05).M-JOA grade was significantly lower on day 30 after operation in group P,while higher on day 30,60 and 90 after operation in group C and PC than that on day 7 after operation(P ＜ 0.05).M-JOA grade was significantly lower at the each time point after operation in group P and C than in group PC.Conclusion The therapeutic effect of PLDD combined with collagenase injection through a target location is stable for treatment of lumbar intervertebral disc herniation and better than that of PLDD or collagenase injection alone.
