Clinical observation of surgical outcomes of lumbar discectomy / 第三军医大学学报

ABSTRACT

Objective To investigate the predictors and characteristics of the surgical outcomes of lumbar discectomy. Methods A total of 204 patients undergoing lumbar discectomy in our hospital from 1985-2003 were selected. The data on the surgical outcomes were collected using questionnaire, communication, and clinical follow-up. The cases were divided into four groups according to the different postoperative time 1-2, 2-4, 4-8 years, and more than 8 years. The correlated factors in surgical outcomes in the four groups were analyzed by multiple regression analysis. The predictors and characteristics of the surgical outcomes in the four groups were compared. Results The duration between symptom onset and operation was significantly associated with the surgical outcomes. There was no statistical difference in surgical outcomes between the four groups. Conclusion The surgical outcomes of lumbar discectomy are closely associated with the preoperative onset of symptoms and remain unchanged in 2 years after operation.
