Osteoporosis is a widespread medical condition among older people. It causes the bones to weaken and become more likely to break. Osteoporosis and bone fracture risk are currently evaluated by looking at clinical risk factors and measuring bone mineral density (BMD). The lower the BMD is, the higher the risk of osteoporotic fractures in the future. An X-ray device called DXA is the main tool used to diagnose osteoporosis and fracture risk clinically. DXA measures two-dimensional BMD in the hip and spine. However, DXA devices are often not readily available at the point of care. The POROUS ultrasound device offers a different approach by measuring various properties of the outer layer of the bone in the lower leg. It has several advantages over DXA: (1) higher and three-dimensional image resolution; (2) the ability to measure bone properties without radiation; (3) portability, it is a mobile medical device; 4) lower operational costs. For this clinical study, we will recruit men and women between the ages of 21 and 55. Most of these study participants will not have evident clinical risks for osteoporosis. The goal for including this age group is to estimate the range of BMD values for younger people before BMD declines with age. In a separate clinical study, we are recruiting older participants. The study is anticipated to last one year. Our major research questions are: * Can the POROUS ultrasound device estimate BMD? * How does its performance compare to DXA? * What is the safety of the new device? The participants will: * answer questions about their medical history. * be measured for height and weight. * be examined with the two devices, DXA and POROUS.
NCT01144377
The primary objectives of this study include evaluating the dose response of LY2541546 using bone mineral density (BMD) change from baseline as compared to placebo and evaluating the overall safety and tolerability of LY2541546 following multiple subcutaneous administrations in postmenopausal (PMP) women with low BMD. Following the last dose of study drug, participants will be able to participate in a 12 month extension to collect additional safety and efficacy data (no further treatment will be administered during this extension).
NCT00176579
RATIONALE: Measuring bone mineral density may help doctors predict whether prostate cancer will come back. It may also help the study of prostate cancer in the future. PURPOSE: This clinical trial is studying whether bone mineral density affects cancer recurrence in patients with early stage prostate cancer.
NCT00587925
Bone Mineral Density (BMD) as measured by X-ray shows the amount of calcium in the bone. Low BMD may reflect osteoporosis, a condition where there is an increased risk of fracture. Women who have gone through menopause have a higher risk of getting osteoporosis because they lose calcium from their bones much faster than younger women. Women with breast cancer may have an additional risk for getting osteoporosis because of the effects of their treatment with chemotherapy. The purpose of this study is to see what levels of BMD post-menopausal women with breast cancer have, and to see if the level of BMD changes during a women's treatment after her surgery. This trial studies changes in BMD and markers of bone activity in women receiving treatment for early stage breast cancer.

NCT00277251
This trial will test the hypothesis that among 20 children and adolescents from Children's Hospital, Boston with Crohn's disease, ulcerative colitis, systemic-onset juvenile rheumatoid arthritis, juvenile dermatomyositis, systemic lupus erythematosus, mixed connective tissue disease and vasculitis, treatment of glucocorticoid-associated osteopenia and osteoporosis with 18 months of alendronate (FOSAMAX®, Merck \& Co., Inc.) will result in greater improvement in the mean change of individual AP spine bone mineral density (BMD) (gm/cm2) determined by dual energy X-ray absorptiometry (DXA) than treatment with 18 months of standard of care therapy.
NCT05387200
This study aims to prove non-inferiority of the efficacy of Masibone S (alendronate sodium trihydrate 70mg, oral solution) on the treatment of postmenopausal osteoporosis compared to the efficacy of Fosamax (alendronate sodium 70mg, oral tablet). The effect of Masibone S and Fosamax on bone mineral density in postmenopausal women with osteoporosis will be compared and analyzed. This study included a total 170 patients (85 per subgroup) for multi-center, randomized, open-label, parallel clinical trial. The drugs will be maintained for a total of 48 weeks. The primary endpoint is the difference of bone mineral density change at lumbar spine measured by DEXA between two groups.
NCT00688246
RATIONALE: Learning about the effect of exemestane on bone mineral density in postmenopausal women at increased risk of breast cancer may help plan treatment, decrease the risk of broken bones, and help patients live more comfortably. PURPOSE: This research study is measuring bone mineral density in postmenopausal women at increased risk of developing breast cancer who are receiving exemestane on clinical trial CAN-NCIC-MAP3.
NCT05937945
Clinical trials for osteoporosis are designed to assess the safety and effectiveness of novel osteoporosis treatments. These trials play a crucial role in establishing whether these new treatments outperform existing options and provide substantial evidence to support their adoption within the wider population. The primary aim of this particular study is to investigate the experiences of individuals diagnosed with osteoporosis who participate in a distinct clinical trial involving a medical intervention. The focus will be on closely monitoring the rates of trial completion and withdrawal among these participants.
NCT00698984
The purpose of this study is to obtain information about the effect of a combination of genistein, PUFAs, vitamin K and D (BONISTEIN(R) bone blend) on bone health, determined as bone mass density/content and bone biomarkers after 6-months treatment in 70 healthy postmenopausal women. In addition, safety and tolerability will be investigated.
NCT02435147
The purpose of this study is to validate the long-term benefit of denosumab for osteoporosis treatment in a real-world clinical practice setting. We hypothesize that continued therapy (36+months) with denosumab will increase both trabecular bone score (TBS) and femur strength index (FSI) and reduce fracture and other bone health risks among post-menopausal women with osteoporosis.
NCT05721898
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.
NCT00114556
Following liver transplantation, rapid bone loss occurs, particularly within the first 6 months post-transplant. This may be associated with fractures, most notable vertebral. The ability to assess osteoporosis therapies in this system may provide useful information for osteoporosis management in general. Hypotheses: 1. That treatment with the bisphosphonate, zoledronate, at the time of liver transplantation and at 1 month post-transplantation will prevent the early transplant-related bone loss (measured by bone densitometry and biochemical bone markers at 3 months) seen in patients who are not treated with a bisphosphonate 2. That continuing treatment with zoledronate at 3 monthly intervals for a total duration of 12 months will result in further improvements in bone density beyond that seen at 3 months 3. That calcium and vitamin D (vit D) supplementation of liver transplant patients does not prevent marked bone loss following transplantation.
NCT02566655
The purpose of this study is to evaluate the safety of intravenous infusion of fucosylated autologous bone marrow cells as a new therapy in patients with established osteoporosis by a prospective, single-center, open, non-randomized and unblinded clinical trial.
NCT00634816
Specific subgroups of children who survive treatment for childhood malignancies have been shown to develop relative osteopenia following chemotherapy and are felt to be at risk for developing osteoporosis later in life due to their inability to reach peak bone mass during childhood.
NCT06567054
Osteoporosis is a widespread medical condition among older people. It causes the bones to weaken and become more likely to break. Osteoporosis and bone fracture risk are currently evaluated by looking at clinical risk factors and measuring bone mineral density (BMD). The lower the BMD is, the higher the risk of osteoporotic fractures in the future. However, most bone fractures occur in people who do not have very low BMD values. This means that osteoporosis and fracture risk are often not diagnosed. Many of these non-diagnosed patients would benefit from treatment to reduce the probability of bone fractures. An X-ray device called DXA is the main tool used to diagnose osteoporosis and fracture risk clinically. DXA measures two-dimensional BMD in the hip and spine. The POROUS ultrasound device measures various properties of the outer layer of the bone in the lower leg. It has several advantages over DXA: (1) its image resolution is higher and three-dimensional; (2) it can detect bone changes without radiation; (3) it can detect these bone changes early and how they change over time. For this clinical study, we will recruit men and women over 55 years old. Most will have clinical risk factors, such as background diseases, for developing osteoporosis. The study is anticipated to last 4 years. Our major research questions are: * Can the POROUS ultrasound device predict fracture risk? * How does its performance compare to DXA? * What is the safety of the new device? The participants will: * answer questions about their medical history. * be measured for height and weight, and take a physical test. * be examined for the presence of 'silent' fractures in the spine. * be examined at the beginning and end of the study with the two devices, DXA and POROUS. * be called by telephone every six months and asked if they suffer from new bone fractures, take any medication that might affect their bones, or if their health status has changed. The participants will be monitored for 3 years.
NCT02156999
To examine the changes of bone mineral density and bone turnover markers after Bonviva treatment in osteoporotic patients
NCT05845021
The goal of this clinical trial is to observe the impact of a surgeon-driven bone health referral pathway following lower extremity arthroplasty. The main question this study aims to answer is: 1\) What is impact of a surgeon-driven bone health referral pathway on implant-related complications and fragility fractures when compared to standard of care primary care provider referral. Researchers will compare the endocrinology referral pathway and standard of care to see if there is a difference in treatment rates, fragility fractures, and implant-related complications following lower extremity arthroplasty.
