Table 3 Operative data of studied patients

Group parameter		Group A	Group B	P value
Group parameter		(n = 92)	(n = 92)	P value
Theater time (min)	Duration of surgical procedure (min)	114 ± 14.2	110 ± 18.7	0.117
	Duration of adjuvant procedure (min)	0	26.4 ± 5.4	0
	Total theater time (min)	114 ± 14.2	136.5 ± 19.6	0.001
Amount of blood loss (cc)		438.9 ± 103	464.3 ± 117.8	0.121

This table shows the non-significant difference between both groups regarding operative time for discectomy and facetectomy, the total theater time was significantly longer in patients of group B than those of group A. There was a non-significant difference between patients of both groups regarding the amount of blood loss and no patient required blood transfusion
