Comparison of the effects and prognosis of percutaneous kyphoplasty with different doses of bone cement in the treatment of thoracolumbar fractures
Objective To analyze the effectiveness of percutaneous kyphoplasty with different doses of bone cement in the treatment of thoracolumbar fractures and its impact on prognosis.Methods The clinical data of 86 patients who underwent percutaneous kyphoplasty in the 904th Hospital of the Joint Logistics Support Force of People's Liberation Army from October 2018 to January 2023 were retrospectively analyzed.All patients underwent percutaneous ky-phoplasty,and were divided into low-dose group(44 cases)and high-dose group(42 cases)according to the amount of bone cement injected during the operation.Followed up for 12 months after surgery,the operation time,number of X-ray irradiation,postoperative hospitali-zation time,anterior vertebral height,central height,kyphotic Cobb angle,degree of back pain,oswestry disability index,and complications were recorded.Results The operation time of the low-dose group was shorter than that of the high-dose group,and the number of X-ray ir-radiation was less than that of the high-dose group(P＜0.05);There was no statistically sig-nificant difference in postoperative hospitalization time between the two groups of patients(P＞0.05).Six months after surgery,the anterior and middle heights of the vertebral bodies in both groups of patients increased compared with those before surgery,while the Cobb angle of ky-phosis decreased compared with that before surgery(P＜0.05);Before and 6 months after sur-gery,there was no statistically significant difference in the anterior edge height,middle height,and posterior convex Cobb angle between the two groups of patients(P＞0.05).Before surger-y,3 months after surgery,and 6 months after surgery,the pain level scores of the two groups of patients decreased sequentially within the group(P＜0.05);At 3 months and 6 months after surgery,the pain scores of patients in the low-dose group were lower than those in the high-dose group(P＜0.05).There was no statistically significant difference in the dysfunction in-dex scores between the two groups of patients before surgery,3 months after surgery,and 6 months after surgery(P＞0.05);At 3 months after surgery,the dysfunction index scores of both groups of patients decreased compared with those before surgery(P＜0.05);At 6 months after surgery,the dysfunction index scores of both groups of patients were lower than those be-fore and 3 months after surgery(P＜0.05).The incidence of postoperative bone cement leak-age in the low-dose group was lower than that in the high-dose group(P＜0.05);There was no statistically significant difference in the proportion of hematoma,and adjacent segment re-current fractures between the two groups of patients(P＞0.05).Conclusion Low-dose bone cement percutaneous kyphoplasty for thoracolumbar fractures can also achieve the effect of high-dose bone cement treatment,and is more helpful in shortening surgical time,reducing postop-erative pain response,and reducing the risk of bone cement leakage after surgery.
