This study aimed to evaluate the clinical effect of different vertebral body heights restoration rate after percutaneous kyphoplasty (PKP) for the treatment of osteoporotic vertebral compression fractures (OVCF). The patients were divided into two groups according to the height restoration rate of the anterior edge of the vertebral body fracture after PKP operation using X-Ray imaging. The group A was below 80%, and the group B was above 80%. Clinical preoperative and postoperative efficacy (1st day, 1st month, 6th month, and 12th month after surgery) were evaluated according to VAS, Oswestry Disability Index(ODI), Quality of Life Questionnaire of the European Foundation for Osteoporosis(QUALEFFO), and Back Pain Life Disorder Questionnaire(RQD). Simultaneously, the preoperative and postoperative local Cobb angles and changes in the injured vertebrae in the two groups were calculated and analyzed. The postoperative Cobb angle in group A was significantly higher than that in group B. The correction rate in group B was significantly better than that in group A. The VAS, ODI, QUALEFFO, and RQD scores of group B patients were significantly lower than those of patients in group A at each follow-up time point. The correlation coefficients of vertebral body height restoration rate and VAS, ODI, QUALEFFO, and RQD scores at the last follow-up were - 0.607 (P
