- Abstract: Objective To explore the outcome of improved percutaneous kyphoplasty(IPKP)for the treatment of thoracolumbar osteoporotic vertebral compression fracture(OVCF),and analyze the risk factors of postoperative bone cement leakage.Methods A total of 115 patients with thoracolumbar OVCF admitted to our hospital from March 2020 to March 2022 were included and divided into the IPKP group(n=64)and the percutaneous kyphoplasty(PKP)group(n=51)according to different surgical methods.The surgery related condition and postoperative complications of patients were recorded.The visual analogue scale(VAS)scores,Oswestry disability index(ODI)scores,anterior vertebral height,middle vertebral height and Cobb angle of patients before surgery and 3 months and 1 year after surgery were compared.The influencing factors of postoperative bone cement leakage were analyzed.Results The operation time of patients in the IPKP group was longer than that in the PKP group(P<0.05),while there was no statistically significant difference in the injected amount of bone cement during the operation between the two groups(P>0.05).The VAS and ODI scores of patients in the two groups decreased 3 months and 1 year after surgery compared with those before surgery(P<0.05),while there was no statistically significant difference in VAS or ODI scores after surgery between the two groups(P>0.05).Three months and 1 year after surgery the anterior and middle vertebral heights of patients in the IPKP and PKP groups increased and the Cobb angle decreased compared with those before surgery(P<0.05).One year after surgery,the anterior and middle vertebral heights in the IPKP group were significantly higher than those in the PKP group(P<0.05),and the Cobb angle was significantly smaller than that in the PKP group(P<0.05).Among the 115 patients with thoracolumbar OVCF,there was no complications such as infection,re-fracture,or vascular embolism occurred after surgery,and there were 13 cases with bone cement leakage,whose risk factor was incomplete endplate/posterior wall(P<0.05).Conclusion Compared with PKP,IPKP in the treatment of thoracolum-bar OVCF has better effect and better recovery of vertebral structure.Incomplete endplate/posterior wall can increase the risk of postopera-tive bone cement leakage,which requires reasonable and effective intervention measures.
