Clinical Analysis Of Percutaneous Kyphoplasty For Severe Osteoporotic Vertebral Compression Fractures

Objective: To compare the clinical efficacy of percutaneous kyphoplasty in the treatment of severe and non-severe osteoporotic vertebral compression fractures(OVCF).Methods: A retrospective analysis of 137 patients with single-segment OVCF who were treated in the Fourth Affiliated Hospital of China Medical University from September 2016 to November 2018,all patients underwent percutaneous kyphoplasty(PKP).According to the degree of vertebral compression(according to the lateral radiograph of the spine,the maximum position of the vertebral compression fracture is greater than or equal to 2/3 of the height of the original vertebral body),it is divided into severe group and non-severe group,of which 23 cases are severe group and 114 cases are non-severe group.Visual Analogue Scale(VAS),The Mos 36-item Short Form Health Survey(SF-36),anterior vertebral body height,s angle and complications were recorded before operation,3 days after surgery and at the last follow-up,and calculate and perform intra-group and inter-group comparisons.Results: The VAS and SF-36 health survey scores at 3 days postoperatively and at the last follow-up were better than preoperative,but there was no difference between the two groups.Anterior vertebral body height and s angle were restored at 3 days after the operation and at the last follow-up.After further calculating the recovery and loss,it was found that the severity of PKP treatment was more obvious in Anterior vertebral body height and s angle of the eccentric surface than in the non-severe group,but there is no difference in the amount of loss.The severe group was more prone to bone cement leakage than the non-severe group,but all patients did not have intraspinal leakage or severe leakage complications such as pulmonary embolism.There was no difference in the new vertebral fractures between the two groups.Conclusions: For patients with severe OVCF,PKP can achieve clinical efficacy comparable to non-severe OVCF.Therefore,PKP is safe,feasible and effective in the treatment of severe OVCF.
