Abstract：【Objective】 To compare the clinical efficacy of percutaneous kyphoplasty (PKP) and percutaneous vertebroplasty (PVP) in the treatment of osteoporotic vertebral compression fractures (OVCF). 【Methods】 A total of 76 patients with OVCF were divided into the PKP group (41 cases) and the PVP group (35 cases) according to different operation methods. Clinical efficacy was compared between the two groups. 【Results】 Compared to before operation, the height of anterior vertebral body in both groups were higher after operation, and the kyphosis Cobb angle and visual analogue scale (VAS) were lower(P<0.05). Compared to before treatment, the Oswestry disability index (ODI) scores of the two groups decreased significantly 1 month after treatment, and the Japanese Orthopaedic Association (JOA) low back pain scores increased significantly (P<0.05). Compared to the PVP group, ODI scores of the PKP group decreased significantly, and the JOA scores increased significantly (P<0.05). Compared to the PVP group, the PKP group had higher anterior vertebral height, lower kyphosis Cobb angle, lower bone cement leakage rate, and higher bone cement injection volume and average treatment cost (P<0.05). There was no significant difference in the incidence of adjacent vertebral fracture and postoperative VAS score between the two groups (P>0.05). 【Conclusion】 Both PKP and PVP can safely and effectively improve the clinical efficacy of OVCF patients and relieve the pain of patients. Compared to PVP, PKP has higher treatment cost, but it can better restore the vertebral shape, improve the vertebral height, and reduce the occurrence of bone cement leakage.
