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.
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.
NCT00433160
To evaluate the efficacy of teriparatide based on measurements of bone mineral density at lumbar spine
NCT03232476
Clinical trial to investigate effect of voluntary upper extremity loading in combination with anabolic osteoporosis 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.
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.
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.
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.
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.

NCT04231682
Organ transplant recipients are known to suffer from bone loss and subsequent fractures after the transplant operation with the most rapid bone loss occurring within the first 3-12 months. Guidelines for prevention and treatment of this serious complication are only written by individual medical societies interested in each organ (separate kidney from liver or heart transplants management) and they are based on studies done with limited medications choices. The majority of studies are done with the use of bisphosphonates, and there are very limited, or no data, on the effect of other medications used for Osteoporosis, including the use of denosumab. This study will focus on the evaluation of the efficacy and safety of denosumab 60mg use early (within first 3 months) after Liver Transplantation in the management of bone loss and prevention of fragility fractures. Different tests will be used to study the effect of the medication on the skeleton, including imaging studies as well as specific labwork.

NCT01935232
Osteoporosis is a disease that leads to impaired skeletal strength and increased fracture risk. Among 200 million osteoporotic patients (Tarantino, Cannata et al. 2007) most are diagnosed only after a fracture. We expect with our aging population to see a significant increase in the prevalence of osteoporosis. It is estimated that over 75% of osteoporotic patients are not diagnosed and do not receive treatment for their condition. This research plan describes a study for clinical validation of the novel ultrasound device (Bindex®, Bone Index Finland Ltd.). In a preliminary study, the technique has been validated in a Finnish postmenopausal woman population of 285 healthy and 56 osteoporotic subjects (n = 341 in total). Significant and good correlation was observed between Density Index (DI) determined with Bindex and femoral neck bone mineral density determined with DXA (r = 0.65 - 0.70). In addition, with determination of 90% sensitivity and specificity thresholds, significant number (65-75%) of patients could be diagnosed without additional verification with DXA. For validation of the technique in US population, our study plan is presented for determination of diagnostic thresholds for osteoporosis. Taken together, DI with Bindex, lumbar spine and femoral bone BMD with DXA are obtained from 500 postmenopausal women and 140 men. The study will be carried out at the HealthEast Osteoporosis Care service in Woodbury, MN. 1. To investigate the capability of DI for prediction of proximal femur and lumbar spine BMD; 2. To develop national diagnostic thresholds for DI in prediction of osteoporosis status with a reference population (American-Caucasian) of 500 (if prevalence of osteoporosis is 20%) post-menopausal females (50-90 years); 3. To investigate ability of Density Index + FRAX with BMI in fracture risk prediction; 4. To investigate correlation between lumbar spine or proximal femur BMD and Density Index in 140 men at wide age range (20-90 years), 70 with osteoporosis and 70 with normal or low bone mass. Determine diagnostic thresholds for DI in men.
