Active clinical trials for "Osteoporotic Fractures"

Osteoporotic fracture is one of the main causes of disability and death in elderly patients. Specific disease cohort study is an important basis for accurate prevention and treatment of senile osteoporotic fractures. Investigators plan to collect and manage the baseline and clinical information of more than 2000 elderly patients with osteoporotic fractures after surgery through the platform of special disease collaborative prevention and treatment system and medical record database of Suzhou Municipal Hospital in two years, and carry out short-term and long-term follow-up observation.

This is a randomized study to determine the effects of monthly romosozumab for one year or one-time zoledronic acid on bone mineral density (BMD) and biochemical markers of bone formation and resorption, in patients with spinal cord injury (SCI) and low BMD.

Osteoporosis is a disease characterized by low bone mass and structural deterioration of bone tissue leading to bone fragility (i.e., weakness) and an increased risk for fracture. Bone strength is a critical factor in a bone's ability to resist fracture and is clearly an important outcome in studies of osteoporosis. The current standard for assessing bone health and diagnosing osteoporosis is to use dual-energy x-ray absorptiometry (DXA) to quantify the areal bone mineral density (BMD), typically at the hip and spine. However, DXA-derived BMD has limited discriminatory accuracy for distinguishing individuals that experience fragility fracture from those who do not. One well known limitation of DXA-derived BMD is that it does not adequately assay bone strength. There is a critical unmet need to identify persons more accurately with diminished bone strength who are at high risk of experiencing a fragility fracture in order to determine an appropriate therapy. A potential new diagnostic approach to assess skeletal health and improve osteoporosis diagnosis is the use of Cortical Bone Mechanics Technology (CBMT). CBMT leverages multifrequency vibration analysis to conduct a noninvasive, dynamic 3-point bending test that makes direct, mechanical measurements of ulnar cortical bone. Data indicates that CBMT-derived ulnar flexural rigidity accurately estimates ulnar whole bone strength and provides information about cortical bone that is unique and independent of DXA-derived BMD. However, the clinical utility of CBMT-derived flexural rigidity has not yet been demonstrated. The investigators have designed a clinical study to assess the accuracy of CBMT-derived ulnar flexural rigidity in discriminating post-menopausal women who have suffered a fragility fracture from those who have not. These data will be compared to DXA-derived peripheral and central measures of BMD obtained from the same subjects.

The investigators' previous studies in 2014 and 2015 have demonstrated that among community-dwelling older adults with high osteoporotic fracture risks. many sarcopenia indices can be improved and bone mineral density (BMD) maintained with different exercise programs. In 2016, the investigators aim to determine the effects of 2 exercise interventions on posture corrections and further improvement of sarcopenic indices

This is a study on the effects of education on secondary fracture prevention in primary health care centers (PHCC) and referral from hospitals to these PHCC of patients with recent fragility fractures. The design is Cluster-randomized controlled study with two arms. 40 primary health care centers (PHCC) are included, each PHCC constitutes a cluster. The intervention group contains 20 PHCCs and the control group of the remaining 20 PHCCs. The educational part of the intervention is divided into three sessions; one web based course succeeded by two multiprofessional seminars with six months interval. During the intervention period patients enlisted at the intervention PHCCs, aged 60 or more who are diagnosed on a fragility fracture are referred to their respective PHCC. The primary outcome are the proportions of patients who receive bone specific treatment after their fracture in the intervention group compared to the control group.

This project anchors osteoporotic fractures, conduct registration and follow-up studies, and conduct prospective treatment studies. By registering for follow-up studies on osteoporotic fractures, it is planned to obtain epidemiological data through registration and follow-up studies; A prospective treatment study for patients with osteoporotic fractures is planned to explore effective treatment strategies through randomized controlled trials; To study biomarkers for osteoporotic refractures, we plan to establish a biomarker warning model through multi omics research; To study imaging biomarkers for osteoporotic refractures, a new imaging technology is proposed to establish an imaging omics warning model.

Cement-augmented pedicle screws (CPS) and hybrid construct (HC) consisting of pedicle screws and additional hooks are common methods in osteoporotic fracture of the thoracic and lumbar spine. No study has compared the surgical results between CPS and HC techniques for treatment of the osteoporotic thoracic and lumbar spine fracture. The aim of the retrospective study was to compare surgical results using CPS or HC for osteoporotic fractures in the thoracic or lumbar spine. Patients who received surgical treatment with CPS or HC for osteoporotic fractures in the thoracic or lumbar spine.

Osteoporosis is a skeletal disease leading to bone fragility and increasing the risk of fractures and still remains a major public health problem worldwide. Therefore it is crucial to prevent severe fractures responsible for excess of mortality and considerable morbidity. Patient at risk of fractures are currently identified as having osteoporosis using Dual-energy X-ray Absorptiometry (DXA), assessing the areal or projected Bone Mineral Density (aBMD g.cm-2). In Chile, the hip fracture occurrence is very similar to the international incidence. Due to the demographic and epidemiological transition, the number of hip fracture for patient older than 50 year, is expected to severely increase from about 6.500 (2007) to 30.000 (2050) without adequate preventive and / or therapeutic measures. Even if DXA remains the current gold standard, it is limited by the difficulty to set a threshold in the BMD distribution for osteoporosis diagnosis. Moreover, some medical conditions (chronic kidney disease, diabetes) or drugs (glucocorticoids) are associated with an increase of fracture risk without a BMD decrease. Quantitative ultrasound (QUS) have the advantages of portability, low cost, absence of radiation and need for a radiographic technologist or designated room, and are sensitive to both elasticity and geometry of the medium explored by the waves. Among QUS techniques, axial transmission (AT) is a technique for which transducers are aligned along the bone axis. Measured ultrasonic guided waves, associated with an appropriate waveguide model have the potential to yield estimates of material and/or geometrical cortical properties. In vivo combined estimation of both cortical thickness and porosity has been proposed using bidirectional axial transmission (BDAT). BDAT measurement has been recently validated on ex vivo specimen (radius and tibia) and has been tested in a pilot clinical study, in which cortical porosity measured at the one-third distal radius has been found as discriminant of low trauma fractures as DXA. Cortical porosity is increasingly recognized as a major contributor to bone fragility. The hypothesis underlying this project are that (1) it is possible to obtain robust and accurate estimates of cortical thickness and porosity using an improved BDAT device and (2) these estimates are of clinical interest in the context of osteoporosis in elderly. Moreover, novel parameters obtained from automatic classification tools will be tested.

Implant anchorage is difficult in patient with osteoporotic bone. To improve the implant bone interface, the ISS stabilization system has been developed. The goal of the study is to investigate the efficacy the ISS augmentation compared to the standard PMMA augmentation of pedicle screws in the treatment of patients suffering from osteoporotic/osteopenic thoracolumbar fracture. The study has two phases, a pilot phase followed by a pivotal phase. The data will be used to measure clinical and radiological performance and usability of both systems.

The purpose of this study is to determine the outcomes of severe osteoporotic fractures hospitalized in France, the risk of incident severe fracture at 2 years and 5 years and the risk of mortality over 2 and 5 years.
