View clinical trials related to Osteoporosis.
Filter by:Osteoporosis is a disease characterized by increased bone fragility and deteriorating bone micro-architecture. The main consequence of osteoporosis is low-trauma fractures, most often of the hip, spine and wrist. Recently, another type of low-trauma fracture, atypical femur fractures (AFFs), have received much attention. Little is known of the cause of these debilitating fractures; however, they have been associated with long term bisphosphonate use. What we currently know about AFFs is based on case reports or small case series, or studies using administrative databases or secondary analyses of bisphosphonate trials. While these reports provide some preliminary information on the relationship between long term bisphosphonate exposure and AFFs, detailed clinical data are absent. As we have established a network of specialists across southern Ontario our group is in a position to collect meaningful information on a larger group of patients who have experienced these debilitating fractures into a centralized AFF registry.
During their lifetime, approximately 50% of Canadian women and 30% of Canadian men will experience at least one fracture due to bone fragility (FF). Evidence is growing regarding prevention programs' effectiveness to prevent falls, but prevention of fractures through fall prevention programs has enjoyed limited success. Falls prevention programs and post-fracture screening programs leading to pharmacological treatment are very different strategies, with a shared ultimate goal. Coordination between those who repair fractures and those who manage the patient to prevent the next fracture is critical. The overarching aim of this proposal is to generate evidence-based knowledge about the effectiveness and cost-effectiveness of an integrated FF prevention program, as well as a portrait of the barriers and facilitating factors for such programs. More specifically, the objectives are: 1) to combine existing fall prevention and post-fracture management programs in the province of Quebec into integrated FF prevention programs; 2) to compare the performance of these integrated programs to control sites, using a pragmatic study design; 3) to identify barriers as well as factors that improve effectiveness across different implementation milieu; and 4) to develop and engage in active knowledge transfer activities in Quebec regions where integrated FF prevention programs are neither adequately nor successfully implemented. Drawing upon the literature on integrated healthcare, fall and fracture prevention, we hypothesize that an integrated FF program can reduce the risk of a subsequent fracture by at least 30% in the population of interest. The proposed team is poised to develop new interdisciplinary collaborations among healthcare practitioners and decision makers involved in the prevention of FFs. The program is built upon existing healthcare and structures and programs and in turn, will truly measure the effectiveness of an integrated FF prevention program. The results will ultimately lead to improvements in the existing knowledge base, address policy-relevant and health systems problems, and assist in the design and implementation of FFs prevention programs.
Osteoporosis is a prevalent health concern among older adults and is associated with an increased risk of falls that can cause fracture, injury or mortality. Identifying the factors related to falls occurring within this population is essential for the development of effective regimes for fall prevention. Studies have shown that muscle quality and good posture alignments are critical for balance control in older adults. People are diagnosed with osteoporosis often combining with muscles weakness, and increased spine kyphosis leading vertebral, fractures and poor balance control, even falls. Therefore, improving muscle quality, strengthening weak muscles and correcting postural alignment are essential elements for fracture and fall prevention in older adults with osteoporosis. The long-term objectives of this work are to prevent fracture and fall in older adults with osteoporosis by improving the function of degenerative muscles using exercise training.
This study will compare the effectiveness of denosumab treatment every 6 months with once yearly zoledronic acid treatment on bone mineral density (BMD) at various skeletal sites.
The overarching aim of this randomized clinical trial is to estimate the effect of dietary intake of calcium as compared to supplemental calcium on the vascular system and markers of vascular and bone health in postmenopausal women.
The primary purpose of participation in this study is to answer whether teriparatide is superior to risedronate in reducing the occurrence of new vertebral fractures during 24 months of therapy.
This open label comparison study examines the hypothesis that teriparatide given immediately following repair of an atypical subtrochanteric or diaphyseal femoral shaft fracture will enhance healing and improve bone mineral density compared to delayed treatment (after six months) with teriparatide or no treatment with teriparatide (patients who refuse therapy or for whom teriparatide is contraindicated). Patients with up-front teriparatide in addition will have greater quality of life measures and less pain compared to those with delayed or no therapy.
Low back pain is a common health issue in elderly population. According to the statistics, more than 80% of Taiwanese suffer low back pain in the life. The cause of low back pain includes lumbar spondylosis, osteoporosis, compression fracture, muscle strain, spondylolisthesis…etc. In addition to drugs and surgery, physical therapy is an alternative choice for conservative treatment. Therefore, in this study, the investigators propose to analyze the physical examination, diagnostic methods, X ray, physical therapy records, physical therapy methods and clinical outcomes in patients with the diagnosis including lumbar spondylosis, low back pain, osteoporosis, compression fracture, back pain treated at National Taiwan University Hospital and received rehabilitation at the Physical Therapy Center in recent ten years.
This study is to evaluate the benefit/risk of hormone replacement treatment among early menopausal women in China. This is a multi-centre, random, prospective study.
Most prevention efforts focus on promoting services (e.g. vaccination, screening tests). While some of these services have clear net benefit, many instead have possible or clear net harm. Currently, three quarters of services graded by the U.S. Preventive Services Task Force (USPSTF) have possible or clear net harm (C, I, and D services). Many of these services are delivered in healthcare settings at higher rates than what might be expected based on their potential for harm. This leads to adverse outcomes, excess costs, and missed opportunities to deliver more quality care. An important issue in delivering prevention messages is how to shift toward a focus on the appropriateness of prevention: encouraging services with clear net benefit and either discouraging or reducing demand for services with possible or clear net harm. Unfortunately, little is known about what drives overuse of potentially harmful screening services or how to make harms relevant to patients. This randomized controlled trial (RCT) of 775 patients at 4 primary care practices aims to 1) assess factors associated with intent to receive possibly or clearly harmful screening services and 2) determine whether and how patients' plans to get screened change with various presentations of information about harms (e.g. qualitative, quantitative, narrative, framed). The investigators will focus on three types of screening services: osteoporosis screening (previous C recommendation and now no recommendation for women < 65 years old with no fracture risk factors), prostate-specific antigen (PSA) screening (D recommendation for all men, regardless of age), and colorectal cancer (CRC) screening (C for ages 76-85).
