New insights regarding osteoporosis treatment and fracture prevention are highlighted in the recent JBJS Guest Editorial What’s New in Osteoporosis: Emphasis on the Aging Athlete. Here, we summarize the 5 most compelling studies, as selected by co-author Ting Cong, MD.
Antiosteoporosis Medications
Researchers investigated whether denosumab use was associated with a decreased risk of developing diabetes in a cohort of 68,510 patients with osteoporosis (mean age, 77.7 years; 84.3% female). The study utilized data from the Taiwan National Health Insurance Research Database. Compared with a propensity-matched control group, the treatment group had a lower cumulative incidence of diabetes. The study authors concluded that these results “may help physicians choose an appropriate antiosteoporosis medication for patients with osteoporosis while also considering the risk of diabetes”1.
A separate study utilized the Taiwan National Health Insurance Research Database to investigate the possible cardioprotective effects of antiosteoporosis medications in a cohort of 41,102 patients ≥40 years old with newly diagnosed osteoporosis. Hormone replacement therapy was associated with a higher likelihood (odds ratio, 1.36) of cardiovascular disease. In contrast, denosumab, teriparatide, and bisphosphonate were each associated with lower odds of cardiovascular disease (odds ratios of 0.13, 0.52, and 0.80, respectively) relative to no drug treatment2.
Osteoporosis Among Men
To help address the lack of established guidelines for routine osteoporosis screening in men, researchers conducted a study to identify the age at which men begin to have an increased risk of fragility fractures. Among men without a pre-existing history of osteoporosis, the risk of fragility fracture increased after 70 years of age (p < 0.001), with the highest risk observed for those ≥81 years of age (p < 0.001)3.
High-Risk Patients on the Fracture Risk Continuum
The relationship between vitamin D level and trabecular bone score, grip strength, and gait speed were investigated in a study of 246 older women with osteoporosis and multiple comorbidities who resided in long-term care centers. After adjusting for covariates, the investigators observed an increase of 0.004 in spinal trabecular bone score (p = 0.0599) and an increase of 0.012 m/s in gait speed (p = 0.0144) for every 5-ng/dL increase in serum 25-OH vitamin D4.
Low-Risk Patients on the Fracture Risk Continuum
The comparative effectiveness of osteoporosis treatments in reducing fracture risk in postmenopausal women was reviewed in a network meta-analysis and meta-regression analysis of 69 randomized controlled trials5. The study demonstrated “the profound positive effect of anabolic agents on bone density in the spine compared with other body parts”, write Guest Editorial authors Dr. Cong et al.
