Clinical application of zoledronic acid combined with vitamin K2 in percutaneous vertebroplasty for multi-segment osteoporotic vertebral compression fractures / 中国骨伤

ABSTRACT

OBJECTIVE@#To explore the clinical effect of zoledronic acid combined with vitamin K2 regimen in percutaneous vertebroplasty for multi-segment osteoporotic vertebral compression fractures(OVCFs).@*METHODS@#This study was a retrospective control study. A total of 364 patients with OVCFs who were admitted to our spinal surgery department from January 2014 to January 2017 were selected as the study subjects. According to whether zoledronic acid combined with vitamin K2 was used to treat osteoporosis after surgery, the patients were divided into control group and experimental group. Among them, 257 patients in the control group were treated with calcium carbonate and vitamin D regimen, while 107 patients in the experimental group were treated with zoledronic acid combined with vitamin K2 regimen on the basis of the control group. Visual analogue scale (VAS) score and Oswestry Disability Index (ODI) were used to evaluate the clinical effect. Pre- and post-operative bone mineral density of lumbar spine and proximal femur, vertebral height ratio of responsible vertebral body and Cobb angle of vertebral body were observed by image data. Serological indicators related to bone metabolism were detected by laboratory. The complications such as fever, dizziness, osteoarthritis, muscular and soft tissue pain and adjacent vertebral re-fracture were compared between two groups.@*RESULTS@#There was no significant difference in general data between the two groups (0.05);VAS score in the experimental group was significantly lower than that in the control group 1 month, 3 months and 1 year after operation(0.05), and at the 24 hours, 3 months, 1 year after operation, the experimental group was significantly lower than the control group (0.05). The vertebral height ratio of the responsible vertebral body in experimental group was significantly higher than that in control group and Cobb angle in experimental group was significantly lower than that in control group at 3 months and 1 year after operation (0.05), but at 3 months and 1 year after operation, the bone mineral density of lumbar spine and proximal femur in experimental group was significantly lower than that in control group (0.05). At 1 year after operation the total type I collagen amino-terminal elongation peptide and β-collagen degradation products in experimental group was significantly lower than that in the control group (<0.05), but the 25-hydroxyvitamin D operation in experimental group was significantly higher than that in control group(<0.05). The incidence of postoperative complications such as fever, dizziness, osteoarthritis, muscle and soft tissue pain and adjacent vertebral re-fracture in experimental group was significantly lower than that in control group (<0.05).@*CONCLUSION@#Zoledronic acid injection combined with vitamin K2 regimen can be used for anti-osteoporosis treatment of OVCFs vertebroplasty. It has a definite curative effect and a high safety factor. It is worth popularizing.
