Comparison of the application effect of two bone cement injection methods in percutaneous vertebroplasty for thoracolumbar osteoporotic compression fractures
Objective To compare the application effect of two bone cement injection methods in percutane-ous vertebroplasty(PVP)for thoracolumbar osteoporotic compression fractures.Methods A total of 62 pa-tients with thoracolumbar osteoporotic compression fractures admitted to Gutian County Hospital from May 2019 to May 2021 were selected as the research objects and divided into observation and control groups ac-cording to the random number table method,with 31 cases in each group.Both groups received PVP treat-ment.The observation group received a lateral opening bone cement injection and the control group received a forward opening bone cement injection.The relevant indicators of surgery,the condition of the vertebral body before and after surgery,the degree of pain before and after surgery,the degree of dysfunction,and the complications were compared between the two groups.Results There were no statistically significant differences between the two groups with respect to operative time and intraoperative blood loss(P>0.05);however,the amount of bone cement injection in the observation group was significantly higher than the control group(P<0.05).The vertebral compression ratios and Cobb angles in the two groups were signifi-cantly decreased 6 months postoperatively compared to the preoperative vertebral compression ratios and Cobb angles,and the height of the injured anterior middle column 6 months postoperatively was significantly increased compared with the preoperative height of the injured anterior middle column in both treatment groups(P<0.05).Moreover,the above-mentioned indicators were not significantly different between the two groups(P>0.05).The visual analogue scale(VAS)and Oswestry dysfunction index(ODI)scores were significantly lower in both groups 7 days postoperatively than preoperatively(P<0.05);the indicators were not significantly different between the 2 groups(P>0.05).The bone cement leakage rate in the obser-vation group was significantly lower than the control group(P<0.05).The incidence of transient hypoten-sion,infections,and pain exacerbation between the two groups was not statistically significant(P>0.05).Conclusions Forward and lateral opening bone cement injection achieved satisfactory efficacy in the treat-ment of PVP for thoracolumbar osteoporotic compression fractures,but lateral injection had a better effect on prevention of bone cement leakage.
