The application of percutaneous cannulated screw fixation in patients with unstable pelvic fractures / 中国基层医药

ABSTRACT

Objective To study the application of percutaneous cannulated screw fixation in patients with unstable pelvic fractures.Methods According to the digital table,98 patients were randomly divided into the two groups,the control group were operated through plate fixation,and the observation group were operated through percutaneous cannulated screw fixation.Results After the surgery,the excellent rates were 89.8％ in the control group and 98.0％ in the observation group,which was significantly higher than that of the control group (x2 =4.68,P ＜ 0.05).The operative time,blood loss,wound length were (121.6 ± 26.4) min,(416.3 ± 39.2) mL,(134.5 ± 21.3) cm in the control group and (81.3 ± 19.2)min,(63.5 ± 12.8)mL,(15.8 ± 2.1)cm in the observation group.The operative time,blood loss,wound length were significantly lower than those of the control group (t =2.961,6.312,8.061,P ＜ 0.05,P ＜ 0.01).Callus occurrence,fracture healing time were (14.2 ± 2.7) weeks,(10.1±2.9) weeks in the control group and (9.1 ± 1.4) weeks,(6.5 ± 1.5) weeks in the observation group.Callus occurrence,fracture healing time in the observation group were less than that of the control group (t =3.061,2.772,P ＜ 0.05).The control group had postoperative complications occurred in 10 patients,with an incidence of 20.4％,and the observation group had three cases of complications,the rate was 6.1％,the complications incidence of the observation group was significantly less than the control group (x2 =6.14,P ＜ 0.05).Conclusion Percutaneous cannulated screw fixation had significant effectiveness for patient with unstable pelvic fractures and fewer complications.
