Clinical Study Of Percutaneous Kyphoplasty With Low-viscosity Bone Cement For The Treatment Of Osteoporotic Vertebral Compression Fractures

Objective: To discuss the clinical effect of low-viscosity bone cement combined with percutaneous kyphoplasty(PKP)in the treatment of osteoporotic vertebral compression fractures.Methods: Retrospective analysis of 62 cases of osteoporotic vertebral compression fractures treated with low-viscosity bone cement combined with percutaneous kyphoplasty(PKP)from Jan.2017 to Jan.2018.Preoperative,3 days after poperation,and 6 months after poperation,the anterior edge height of the fracture vertebrae,the sagittal plane Cobb Angle of the fracture vertebrae,visual analogue scale(VAS)and Oswestry disability index(ODI)were compared.Results: All the patients in this group completed the surgery successfully,among which 5 patients had bone cement pervertebral tissue leakage and 3 patients had bone cement intervertebral disc leakage.All patients were followed up for more than 6 months.Three days after operation,patients had less VAS and ODI scores compared with preoperative values,respectively(P<0.001).At 6-month follow-up,all patients showed much less VAS and ODI scores compared with three days after operation values,respectively(P<0.001).The anterior edge height of the fracture vertebrae at 3days after operation was significantly higher than preoperative(t=?13.275,P<0.001).However,there was no difference in the height of fracture vertebra between 3 days after operation and 6-month follow-up(t=1.431,P=0.073).The sagittal plane Cobb Angle of the fracture vertebrae at 3days after operation was significantly smaller than preoperative(t=9.874,P<0.001);The Cobb Angle of the sagittal plane of the vertebral body of all patients changed little at 6 months after operation compared with 3 days after operation(t=0.351,P=0.863).Conclusion: Low-viscosity bone cement combined with percutaneous kyphoplasty(PKP)can effectively alleviate the pain symptoms of patients with osteoporosis vertebral compression fracture,and has significant effects in restoring the height of the injured vertebrae,correcting the sagittal plane Cobb Angle of the injured vertebrae,improving the quality of life of patients,and the incidence of complications is low,so satisfactory early clinical efficacy can be achieved.
