Table 2 Comparison of operation indexes among the three groups

Operation indexes	COPSF group	PPSF group	POPSF group
Operating time (min)	125.3±23.4	98.4±25.3^a	97.6±19.6^b
Intraoperative blood loss (ml)	367.9±37.6	107.9±18.7^a	140.1±25.8^b,c
Intraoperative fluoroscopy (times)	3.3±1.1	28.4±1.4^a	3.7±1.3^c
Hospital stay (days)	14.4±1.8	10.1±2.1^a	11.2±2.8^b
Hospitalization cost (×10³ CNY)	49.9±0.9	55.2±1.0^a	48.6±1.3^c

One-way ANOVA was used to compare the operating times and the hospitalization costs. Wilcoxon rank sum tests were used to compare the intraoperative blood loss, intraoperative fluoroscopy, and hospital stays
