Objective To compare the effects of angular and unilateral vertebroplasty on spinal compression fractures in the elderly.Methods A total of 122 elderly patients with spinal compression fractures admitted to the Department of Orthopedics,Handan First Hospital from January 2018 to January 2021 were selected as the research subjects.They were divided into a control group and an observation group according to the surgical method,with 61 patients in each group.Patients in the control group were treated with unilateral vertebroplasty,while patients in the observation group were treated with angular vertebroplasty.The operation time,intraoperative blood loss and bone cement injection volume,bone cement distribution,bone cement leakage,spinal-pelvic parameters,visual analogue score(VAS),Barthel index score,and the occurrence of complications were compared between the two groups.Results There was no statistically significant different in the operation time,intraoperative blood loss and bone cement injection volume between the two groups(P＞0.05).The proportions of grade Ⅰ,grade Ⅱ,grade Ⅲ and grade Ⅳ bone cement distribution also showed no significant difference between the two groups(P＞0.05).The total proportion of grade Ⅰ and grade Ⅱ bone cement distribution in the observation group was significantly higher than that in the control group(P＜0.05).The incidence of bone cement leakage in the observation group was significantly lower than that in the control group(P＜0.05).Before operation,there was no statistically significant difference in sagittal balance,thoracic kyphosis angle,pel vic tilt angle,lumbar lordosis angle,and sacral slope angle between the two groups(P＞0.05).After operation,the sagittal balance,thoracic kyphosis angle and pelvic tilt angle significantly decreased in the two groups compared to before operation,and the sagittal balance,thoracic kyphosis angle and pelvic tilt angle of patients in the observation group were significantly smaller than those in the control group(P＜0.05);the lumbar lordosis angle and sacral slope angle significantly increased in the two groups compared to before operation,and the lumbar lordosis angle and sacral slope angle of patients in the observation group were significantly greater than those in the control group(P＜0.05).Before operation,there was no statistically significant difference in the VAS score and Barthel index between the two groups(P＞0.05).Three months after operation,the VAS score of patients in the two groups decreased,while the Barthel index increased compared to before operation(P＜0.05);the Barthel index of patients in the observation group was significantly higher than that in the control group(P＜0.05),while the VAS score showed no significant difference between the two groups(P＞0.05).During treatment,1 case of extraspinal hematoma occurred in the observation group,and the complication rate was 1.64％(1/61);in the control group,2 cases of extraspinal hematoma and 1 case of incision infection occurred,and the complication rate was 4.92％(3/61).There was no statistically significant difference in the incidence of complications between the two groups(x2=1.034,P=0.309).Conclusion Compared with unilateral vertebroplasty,angular vertebroplasty has better effect of bone cement distribution in treating elderly patients with spinal compression fractures,and it can improve the spiral balance and enhance the postoperative quality of life.
