ABSTRACT

[Objective]To analyze the relative factors of reoperation to lumbar disc herniation(LDH)and to discuss the three methods for reoperation.[Method]By retrospectively studying and analyzing etiopathogenisis in 102 cases,who were made at least one reoperation,and other(1 327) LDH patients underwent an initial standard discectomy in our department from 1999 to 2004.Then studied several relative factors,such as age,interval time between the initial operation to the first reoperation,was made stastistic analysises.Combined with the statistic results,the clinical outcomes of patients who underwent three different reoperative methods were evaluated.[Result]A total of 102 cases underwent at least one reoperadon,11 of them had multiple(two or more)reoperations.Among these patients 58 cases suffered from recurrent LDH,40 suferred from postoperative stenosis or instability and 4 had postoperative intervertebral-space-infection.Forty-eight cases(47.06%)were performed single discectomies again,20(19.61%)undergone decompressions by laminectomy and 34(33.33%)had decompressions,bone-grafting and fixed with spinal instrumentations.There were 16 patients in all interbody-fusion surgeries and the number increasd year by year.Higher reoperation rate was seen in patients with the initial operation taking place less than 1 year comparing,more than those with the initial operation performing more than 1 year ago(P
