Abstract:
OBJECTIVETo provide theoretical basis for effect and mechanism of percutaneous lumbar discectomy in clinic.
METHODSA total of 180 patients with lumbar intervertebral disc herniation were evaluated by CT on the fifth day before and after operation. Meanwhile, CT value was measured in the determined level and region.
RESULTSAfter operation, CT value of the central and posterior determined point of herniated intervertebral disc was lower significantly than that before operation (P<0.01), but CT value of the anterior determined point was different insignificantly. The excellent and good results of the patients together were 83% postoperatively.
CONCLUSIONSThe curative effect of percutaneous lumbar discectomy is achieved through reduction of lumbar intradiscal pressure.
