【Abstract】 Objective To analyse the causes of failure in percutaneous lumbar discectomy (PLD) so as to provide preventive measures and decrease the reoperative rate. Methods From Aug. 1995 to Mar. 1999, 146 cases of lumbar disc herniation (LDH) were treated with PLD and 16 failure patients undergoing reoperation were evaluated. Results The causes of failure of PLD were mainly due to inadequate decompression, diagnostic errors of multilevel LDH, and LDH with calcication. 87.6% of the patients after reoperation obtained excellent and good results. Conclusion Selection of patients for the operation of PLD should be strict and the technic of operation must be skilled, reoperation would then be reduced or avoided.更多还原
