Osteoporosis causes an elevated fracture risk. We propose the continued use of T-scores as one means for diagnosis but recommend that, alternatively, hip fracture; osteopenia-associated vertebral, proximal humerus, pelvis, or some wrist fractures; or FRAX scores with ≥3% (hip) or 20% (major) 10-year fracture risk also confer an osteoporosis diagnosis. ⋯ As new ICD-10 codes become available, it is our hope that this new understanding of what osteoporosis represents will allow for an appropriate diagnosis when older individuals are recognized as being at an elevated risk for fracture.

Patients receiving alendronate for osteoporosis carry a significantly higher risk of developing upper gastrointestinal bleeding (GIB) and lower GIB (hazard ratio 1.32 and 1.84, respectively) after adjusting for potential confounding factors such as age, gender, co-morbidity, and some medications. The risk factors associated with GIB were further analyzed. ⋯ Patients receiving alendronates seemed to carry a higher risk for UGIB and LGIB, respectively, after adjustment for age, sex, underlying comorbidity, and certain medications.

Kyphoplasty has been shown to provide symptomatic relief of vertebral compression fractures refractory to medical therapy. However, few reports have focused on refracture of cemented vertebrae after kyphoplasty. The presence of cemented vertebrae refracture concurrent with cement fragmentation is an extremely rare condition. ⋯ The patient finally obtained therapeutic benefit of pain relief and bony union of T12 vertebral body by consistently adhering to anti-osteoporotic medication treatment. This case illustrated that patients who underwent kyphoplasty to treat osteoporotic vertebral compression fractures with intravertebral fracture should be strictly followed up and supervised in their anti-osteoporotic medication treatment. The interdigitation injection pattern of PMMA and sufficient PMMA filling with trabeculae in the kyphoplasty procedure also might prevent refracture of the cemented vertebrae concurrent with PMMA fragmentation.

In vitro data suggest that myokine irisin may affect bone metabolism by promoting osteoblast differentiation while inhibiting osteoclast differentiation. In this study, circulating irisin levels were associated with previous osteoporotic fractures but not with bone mass and were not affected by denosumab or teriparatide treatment for 3 months. ⋯ Circulating irisin levels were associated with previous osteoporotic fracture(s); whether this association is independent or is due to confounding by lower muscle mass, potentially reflected by lower creatinine levels, remains to be fully clarified.
