AbstractVertebroplasty (VP) effectively treats vertebral compression fractures (VCFs). However, the issue of secondary new VCFs (SNVCFs) after VP is yet to be addressed. Therefore, identification of risk factors for SNVCFs after VP may aid the development of strategies to minimize SNVCF risk. This study aimed to retrospectively evaluate risk factors for SNVCFs after VP, including those associated with the type of anti-osteoporotic treatment administered after VP. Data from 128 patients who underwent single-level VP were collected and reviewed. Patients were divided into 2 groups: those with (n = 28) and without (n = 100) SNVCF within 1 year of VP. We collected the following patient data: age, sex, site of compression fracture, medical history, bone mineral density (BMD), history of long-term steroid use, history of osteoporosis drug use, duration between fracture and VP, VP implementation method (unilateral or bilateral), cement usage in VP, cement leakage into the disc, compression ratio before VP, pre- and postoperative recovery ratio of the lowest vertebral body height, and kyphotic angle of fractured vertebrae. These data were analyzed to identify factors associated with SNVCFs after VP and to investigate the effects of the type of anti-osteoporotic treatment administered for SNVCFs. SNVCFs occurred in 28 patients (21.9%) within 1 year of VP. Logistic regression analysis identified BMD, cement leakage into the disc, and long-term steroid use to be significantly associated with the occurrence of SNVCFs. The group treated with zoledronate after VP had a significantly reduced SNVCF incidence compared with the group treated with calcium (P < .001). In addition, the zoledronate group had a lower SNVCF incidence compared with the groups treated with alendronate (P = .05), selective estrogen receptor modulators (P = .26), or risedronate (P = .22). This study showed that low BMD, presence of an intradiscal cement leak, and long-term steroid use were risk factors for developing SNVCFs following VP. Additionally, among osteoporosis treatments prescribed for VP, zoledronate may be the preferred choice to reduce the risk of SNVCFs.Copyright © 2023 the Author(s).
