Vertebroplasty does not play a role in further fracture prevention. Antiresorptive agents are widely used to treat osteoporosis. Data from clinical trials show that antiresorptive agents (raloxifene and alendronate) reduce the risk of vertebral fracture by 40% to 50% after 3 years of treatment [9, 10]. Nonetheless, in the
treatment of severely osteoporotic patients, Entospletinib the therapeutic effect of antiresorptive agents is too slow, and the use of these agents is associated with a high risk of new-onset fractures. Teriparatide (rDNA origin) injection [recombinant human PTH(1–34)] is the first bone anabolic agent for the treatment of osteoporosis. Teriparatide administered once daily through subcutaneous self-injection results in a rapid and greater increase in vertebral bone mineral density (BMD) and a decreased risk of vertebral and non-vertebral fractures in postmenopausal women and men with osteoporosis [11, 12]. Teriparatide, with a mechanism different from that of antiresorptive agents, preferentially increases bone formation through direct early stimulation of osteoblasts. This increase in new bone formation results in a positive bone balance at the level of individual bone multicellular units and improved bone microarchitecture and quality [13]. We hypothesized that treating the learn more adjacent VCF after PVP requires a faster increase DNA Damage inhibitor in new bone
formation and improved bone strength and quality. This prospective cohort study aimed to assess the immediate and mid-term efficacy and safety of teriparatide for treatment of new-onset adjacent compression fractures after PVP. We prospectively compared the therapeutic effects of teriparatide and combined vertebroplasty with an antiresorptive agent in fracture prevention, BMD increase, and sustained pain relief. Patients and methods Patients All patients provided informed written consent before participating. We identified 50 patients who had
adjacent VCFs after vertebroplasty from November 2007 to December why 2010. VCF was diagnosed based on radiologic findings in all patients. All patients underwent magnetic resonance imaging (MRI) examinations for definitive diagnosis of new-onset osteoporotic VCFs when they had their first painful VCF. The exclusion criteria were spinal cancer, neurologic complications, osteoporotic vertebral collapse of greater than 90%, fracture through or destruction of the posterior wall, retropulsed bony fragmentation or bony fragments impinging on the spinal cord, medical conditions that would make the patient ineligible for emergency decompressive surgery if needed, and a likelihood of noncompliance with follow-up. All subjects completed a baseline questionnaire that inquired about use of alcohol and cigarettes, rheumatic arthritis, history of spine or other bone fractures, and history of corticosteroid use.
