Objective   To analyse explore the importance of the risk factors of the strength of postoperative recurrence risk factors in of spinal tuberculosis.    Methods   Totally 486 patients suffering from spinal tuberculosis and receiveding surgery from January 1998 to December 2007 in our department were subjected. They were  followed up for 1 to 3 years and divided into 2 groups according to time course. Group 1 (n=129) was the  patients treated during the period of 1998 to 2002

including 34 cases with recurrence and 95 without

and group 2 (n=357) were the patients operated from 2003 to 2007

including 27 case with recurrence and 330 without. We compared their clinical data

such as the nutrition

the extent of lesions

whether clearing the lesion surgically

whether having formal pre- and post-operative medication

drug therapy

and whether strictly stayed in bed after surgery. At last

we analyzed the importance of these risk factors of postoperative recurrence of spinal tuberculosis.    Results   In group 1

whether strictly stay in bed after surgery was the strongest risk factor. In group 2

whether having preope-rative drug therapy was the strongest risk factor.    Conclusion   We should strengthen drug therapy

and then

the postoperative recurrence of spinal tuberculosis could be controlled.
