The upper and lower thoracolumbar spine have been associated with different biomechanical outcomes. This concept, as it applies to osteoporotic fracture risk, has not been well documented. This was a case-control study of 120 patients seen in an osteoporosis clinic. Vertebral fractures were identified from lateral radiographs using Genant's semi-quantitative assessment method. An association between bone mineral density (BMD) T-scores and vertebral fracture location was assessed. In an additional analysis, the association between a history of any traumatic injury and possible predictor variables was also explored...

BACKGROUND: Fibroblast growth factor (FGF23) is a protein that is produced by osteoblasts and osteocytes. Increased serum levels of FGF23 have been associated with increased risks of osteoporotic fractures and cardiovascular disease, particularly in participants with poor renal function. Serum iron (Fe) has been suggested as a regulator of FGF23 homeostasis. OBJECTIVE: To determine whether Fe and iron status are determinants of the levels of intact FGF23 (iFGF23) in elderly men...

: We constructed a Markov microsimulation model among hypothetical cohorts of community-dwelling elderly osteoporotic Japanese women without prior hip or vertebral fractures over a lifetime horizon. Compared with weekly oral alendronate for 5 years, denosumab every 6 months for 5 years is cost-saving or cost-effective at a conventionally accepted threshold. INTRODUCTION: The objective of the study was to examine the cost-effectiveness of subcutaneous denosumab every 6 months for 5 years compared with weekly oral alendronate for 5 years in Japan...

INTRODUCTION: The management of highly comminuted distal radius fractures still remains a major treatment challenge. Articular comminution and compromised bone quality are the culprits. One novel approach is the technique of Internal Distraction Plating which involves "bridging" the fracture with the use of a standard 3.5mm plate applied dorsally in distraction from the radius, proximal to the fracture, to the long finger metacarpal distally, bypassing the comminuted segment. The plate is removed once fracture union has been achieved...

Osteoporosis (OP) increases the risk of bone fractures and other complications, and is thus a major clinical problem. In this study, we examined the effect of isopsoralen on the differentiation of bone-derived marrow mesenchymal stem cells (BMSCs) into osteoblasts and adipocytes, as well as bone formation under osteoporotic conditions. Primary femoral BMSCs isolated from C57BL/6 mice were used to evaluate the isopsoralen-mediated regulation of the expression of alkaline phosphatase (ALP), osteocalcin (OCN) and runt-related transcription factor 2 (RUNX2) during osteogenesis 2 weeks...

BACKGROUND: Bisphosphonates (BPs) are one of the most commonly used agents in the treatment of post-menopausal osteoporosis and other metabolic bone diseases. METHODS: Between 2010 and 2015, data of 22 osteoporotic women with femoral fractures due to low-energy trauma who received BPs previously were analysed. RESULTS: The mean duration of BP therapy was 7.6 years. The mean duration of union was 7.4 months. Five patients had non-union. Stress reaction was observed in the contralateral femur in 11 patients...

INTRODUCTION: In an ageing population the prevalence of osteoporosis and chronic respiratory diseases is expected to increase in the near future. Interestingly, several forms of corticosteroids, drugs implicated in osteoporosis pathogenesis, are prescribed to respiratory patients without taking into consideration their age and risk for osteoporotic fractures. The aim of this study was to investigate the risk for hip fracture of the elder individuals who are taking corticosteroids for respiratory disease, including inhalers...

Background. Interest in arthroplasty techniques for periarticular or intra-articular fractures in the elderly/osteoporotic patient continues to rise, including for geriatric acetabular fractures. In line with this, many acetabular fracture surgeons are now undertaking acute total hip arthroplasty in elderly/osteoporotic patients. Little is known however of the outcomes of this procedure, beyond the first year after surgery. Questions/Purposes. We determined the clinical outcomes of a series of elderly osteoporotic patients (mean age at surgery 77...

Elevated vertebral bone marrow fat (BMF) among individuals with osteoporosis has been established in histomorphometric studies. Several studies have found a negative correlation between BMF and bone mineral density (BMD) at the spine in men and women across different age groups. Animal studies have also observed bone loss with increased BMF in mice with induced diabetes. Our study objective was to test the hypothesis that the association between BMF and BMD varies by diabetic status. We performed a cross-sectional study of 156 men aged 74-96years from the Osteoporotic Fractures in Men (MrOS) study at the Pittsburgh clinical site...

Extreme phosphate levels (P) have been associated with mineralization defects and increased fracture risk. Whether P within normal range is related to bone health in the general population is not well understood. To investigate the association of P with bone mineral density (BMD) and fracture risk, we assessed two population-based cohorts: the Dutch Rotterdam Study (RS-I, RS-II, RS-III; n = 6791) and the US Osteoporotic Fractures in Men (MrOS; n = 5425) study. The relationship of P with lumbar spine (LS) and femoral neck (FN) BMD was tested in all cohorts via linear models; fracture risk was tested in RS-I, RS-II and MrOS through Cox models, after follow-up of 8...

BACKGROUND: Urinary stone disease (USD) is increasing in adult and pediatric populations Adult and pediatric studies have demonstrated decreased bone mineral density and increased fracture rates. USD has also been independently linked to increased rates of myocardial infarction and cerebral vascular accidents. Although USD is a multisystem disorder involving the kidneys, bone and vasculature, the molecular mechanisms linking these three organs remain unknown. METHODS: Calcium oxalate nephropathy was induced in C57BL/6J mice with intra-peritoneal (ip) injection of sodium glyoxolate...

BACKGROUND: In a previous population-based study on 3369 European men with self-reported prostate cancer (PCa), it was shown that androgen receptor (AR) haplotype designated H2 was associated with high levels of serum PSA (prostate-specific antigen) concentration, and, at the same time, with low risk for PCa. The aim of this study was to replicate this finding in other cohorts, with registry-based cancer diagnosis. METHODS: Using data from two population-based cohorts; the Malmö Diet and Cancer Study (MDCS, n = 12,121) and the Swedish Osteoporotic fractures in men study (MrOS, n = 1,120), 628 men with PCa and 1,374 controls were identified and genotyped...

Bisphosphonates are considered first-line agents in the treatment of postmenopausal osteoporosis based on extensive experience of use, safety, and proven efficacy in reducing vertebral, non-vertebral and femur fractures. However, post-marketing reports based on the treatment of millions of patients/year over lengthy periods of time have revealed the occurrence of initially unexpected adverse effects, such as osteonecrosis of the jaw and atypical femoral fracture, leading to the restriction of treatment duration with bisphosphonates by global regulatory agencies...

We investigated the prevalence and incidence of vertebral fractures worldwide. We used a systematic Medline search current to 2015 and updated as per authors' libraries. A total of 62 articles of fair to good quality and comparable methods for vertebral fracture identification were considered. The prevalence of morphometric vertebral fractures in European women is highest in Scandinavia (26%) and lowest in Eastern Europe (18%). Prevalence rates in North America (NA) for White women ≥50 are 20-24%, with a White/Black ratio of 1...

OBJECTIVES: We assessed how reprocessed and damaged drill bits perform relative to new drill bits in terms of drilling force required, heat generated at near and far cortices, and number of usable passes. METHODS: Nine pairs of non-osteoporotic human cadaveric femora were tested using 3 types of 3.2-mm drill bits (new, reprocessed, and damaged) in 3 investigations (force, temperature, and multiple usable passes). Operating room conditions were simulated. Force and temperature data were collected for each type...

The decline of tissue function in ageing is a consequence of many changes in the gene expression and other extrinsic factors. The molecular mechanisms underlying these changes are heavily investigated with focus on regulation of time-lapse gene expression. microRNAs, short non-coding RNA molecules are among the major regulators of gene expression. microRNAs have been shown to control ageing-related mechanisms and several evidence suggest age-related changes in microRNA transcriptome. However, the source regulator of time-lapse gene expression control still remains unknown...

Osteoporosis is a common disease in the elderly, which is related to fracture healing delay. In this study, the effects of treatment with sialoglycoprotein isolated from the eggs of Gadus morhua (Gm-SGP) on tibial fracture healing in ovariectomized (OVX) osteoporotic female C57BL/6J mice for 56 days post-fracture were investigated. The result showed that Gm-SGP treatment significantly increased serum angiogenic factors and bone formation markers on day 5 and 11 post-fracture when compared with the OVX group...
