The phase 3 teriparatide Fracture Prevention Trial showed significant reductions in vertebral (VF) and nonvertebral (NVF) fractures; however, patient exposure was insufficient for full analysis of low-incidence fractures, including hip. We assessed fracture results in pooled data from four prospective, observational teriparatide studies. Ambulatory women and men with osteoporosis received subcutaneous teriparatide 20 µg/day for up to 24 months per routine clinical practice. Fracture rates were compared between 6-month periods, using 0 to 6 months of treatment as the reference period...

Male osteoporosis can occur with advanced age and with hypogonadism, with increased bone resorption and/or inadequate bone formation contributing to reduced bone mass and increased fracture risk. Abaloparatide is a selective PTH receptor agonist that increases bone formation and bone mass in postmenopausal women with osteoporosis and in estrogen-deficient animals. The current study evaluated the effects of abaloparatide in orchiectomized (ORX) rats, a model of male osteoporosis. Four-month-old Sprague-Dawley rats underwent ORX or sham surgery; 8 weeks later the ORX groups exhibited relative osteopenia vs sham controls, based on dual X-ray absorptiometry (DXA) and/or peripheral quantitative computed tomography (pQCT) assessments at the total body, lumbar spine, femur, and tibia...

INTRODUCTION: Proximal femoral fracture is associated with severe morbidity and mortality and high socioeconomic costs. The main mechanical complication of internal fixation in trochanteric fracture is lag-screw cut-out through the femoral head. Several factors are involved, but remain controversial. The aim of the present study was to determine risk factors for cut-out in internal fixation of extracapsular proximal femoral fracture. METHODS: A single-center retrospective study was conducted on a continuous series of 228 patients aged over 75 years, operated on for trochanteric fracture by gamma3 nail or DHS screw plate between July 2009 and December 2014...

Vitamin D is essential for the maintenance of calcium and phosphorus homeostasis, skeletal growth and various other metabolic processes. The prevalence of vitamin D deficiency in India is 50-90% in various studies. Factors such as low sunlight exposure, age-related decrease in cutaneous synthesis, and low dietary intake of vitamin D contribute to the high prevalence of vitamin D inadequacy which has emerged as a highly pervasive condition. Bone diseases such as rickets in children, osteomalacia and osteoporosis in adults are related with vitamin D insufficiency...

Limited information is available on the impact of bisphosphonate compliance levels on fracture risk in osteoporosis patients in France. The results of this nested case-control, retrospective study suggest that fracture risk did not significantly change with bisphosphonate compliance levels, except for highly compliant patients. PURPOSE/INTRODUCTION: This was the first study conducted in France to evaluate the impact of compliance levels for bisphosphonates, the most frequently prescribed first-line anti-osteoporotic treatment, on fracture risk...

Osteoporosis represents a major health problem in terms of compromising bone strength and increasing the risk of bone fractures. It can be medically treated with bisphosphonates, which act systemically upon oral or venous administration. Further, bone regenerative treatments in osteoporotic conditions present a challenge. Here, we focused on the development of a synthetic bone substitute material with local diminishing effects on osteoporosis. Composites were created using calcium phosphate cement (CPC; 60 wt%) and polylactic-co-glycolic acid (PLGA; 40 wt%), which were loaded with alendronate (ALN)...

BACKGROUND: Patients with chronic obstructive pulmonary disease have a high prevalence of osteoporosis, and different osteoporosis drugs are used to prevent fractures in these patients. Although the overall incidence of complete or incomplete, atypical femoral fracture (AFF) is low, long-term use of antiresorptive agents is associated with an increased risk of developing AFF. METHODS: We present a patient with chronic obstructive pulmonary disease with recurrent symptoms of an incomplete AFF who had been treated with glucocorticoids, and sequentially with alendronate, zoledronic acid, strontium ranelate, raloxifene, denosumab and finally with teriparatide...

Magnus Bernhardsson, Per Aspenberg
Background and purpose - Teriparatide accelerates fracture healing in animals and probably in man. Abaloparatide is a new drug with similar although not identical effects on the teriparatide receptor. Given at 4 times the teriparatide dose in a human osteoporosis trial, abaloparatide increased bone density more than teriparatide, and both reduced fracture risk. We investigated in mice whether abaloparatide stimulates fracture healing, and if it does so with the suggested dose effect relation (4:1). Patients and methods - In a validated mouse model for metaphyseal healing (burr hole with screw pull-out), 96 mice were randomly allocated to 11 groups: control (saline), teriparatide or abaloparatide, where teriparatide and abaloparatide were given at 5 different doses each...

The association between osteoporosis and polycyclic aromatic hydrocarbons was not clear. However, recent studies showed that both osteoporosis and polycyclic aromatic hydrocarbons were associated with reactive oxygen species. So we presumed that polycyclic aromatic hydrocarbons were associated with increased odds of osteoporosis. We found 3-hydroxyfluorene was associated with decreased odds of osteoporosis, while 2-hydroxyfluorene was associated with increased odds of osteoporosis. PURPOSE: Previous studies showed that polycyclic aromatic hydrocarbons were involved in the production of reactive oxygen species that played an important role in illness...

BACKGROUND: Bony increased-offset reverse shoulder arthroplasty (BIO-RSA) may address issues such as inferior scapular notching, prosthetic instability and limited postoperative shoulder rotation; all of which have been reported with the standard RSA and attributed to the medialized design. We hypothesised that this lateralization may increase the rate of scapular stress fractures. METHODS: A retrospective review of prospectively collected data was performed on patients who had undergone a RSA between January 2013 and October 2016...

Osteoporosis is a common complication of androgen deprivation therapy (ADT). In this large Swedish cohort study consisting of a total of nearly 180,000 older men, we found that those with prostate cancer and ADT have a significantly increased risk of future osteoporotic fractures. INTRODUCTION: Androgen deprivation therapy (ADT) in patients with prostate cancer is associated to increased risk of fractures. In this study, we investigated the relationship between ADT in patients with prostate cancer and the risk of incident fractures and non-skeletal fall injuries both compared to those without ADT and compared to patients without prostate cancer...
