16 Clinical Trials for Osteopenia
To compare the diagnostic accuracy of extra-oral x-rays with intra-oral x-rays, in contrast to clinically observed measurements, for the detection of calculus and bone loss of either the suprabony or infrabony types in patients undergoing periodontal surgery.
This phase III trial tests whether high-dose vitamin D works in treating androgen-deprivation therapy (ADT)-induced bone loss in patients with prostate cancer who are undergoing androgen-deprivation therapy. Vitamins are substances that the body needs to grow and develop normally. Vitamin D helps the body absorb calcium. Calcium is one of the main building blocks of bone. A lack of vitamin D can lead to bone diseases such as osteoporosis or rickets. This trial may help researchers determine if high-dose vitamin D helps keep bones strong, lowers number of falls, and lessens fatigue in men getting androgen-deprivation therapy.
The purpose of this research study is to see whether receiving a bisphosphonate medication called risedronate can reduce bone and muscle loss following bariatric surgery. Participation will involve up to 6 study visits and last about 1 year. Risedronate is a medication that prevents bone breakdown and has been approved by the US Food and Drug Administration (FDA) for the prevention and treatment of osteoporosis in older men and women. However, risedronate has not been approved for the prevention of bone and muscle loss following vertical sleeve gastrectomy. Participation in this study will involve completing two visits before beginning the intervention. Participants who qualify will be scheduled to begin the intervention program which will involve taking 6 monthly doses of a risedronate or placebo pill. Participants will then receive monthly contacts by study staff during this time to remind participants to take the intervention pill and ask about any adverse events. After the completion of intervention period, participants will complete up to 4 follow up study visits at 6 months (2 visits) and at 12 months (2 visits).
This clinical trial will investigate the effects of three surgical procedures and the associated post-operative rehabilitation to optimize time to return to military duty, work and sports, and patient-reported physical function for military personnel and civilians with traumatic anterior shoulder instability and 10-20% glenoid bone loss.
The purpose of this research is to identify strategies that minimize bone loss that occurs when older adults lose weight. Participation in this research will involve up to nine assessment visits and last up to two years.
The purpose of this clinical trial is to assess if the addition of DFDBA fibers to DBBM results in greater vital bone formation than the addition of DFDBA particles to DBBM. The study team will examine the effects of the addition of DFDBA fibers to DBBM on vital bone formation. Specifically, we will assess histologically the percent vital bone formation with each of the groups during implant placement, six months after the sinus augmentation procedure. We will also evaluate the radiographic volume achieved with both groups of materials.
Patients with Type 1 Diabetes Mellitus (T1DM) have a higher risk of low-trauma (osteoporotic) fracture that is 7-12 times higher than non-diabetics. The bone density of people with Type 1 Diabetes is higher at the time of fracture than in non-diabetics. This suggests the presence of underlying bone tissue mechanical defects. The potential benefits to participants would be knowledge gained about their bone density and the results of laboratory tests. On a wider scale, there may be general benefits to society because the knowledge gained from this study may help better understand the effects of diabetes on bone health
The goal of this clinical trial is to learn the impact of lutein, zeaxanthin, and fish oil (LZF) supplementation in healthy adults. The main question it aims to answer is: Will supplementation with LZF improve macular pigment optical density (MPOD), cognitive performance and bone mass compared to controls after six months? Subjects with an MPOD \<.43 will significantly improve MPOD after 6-months of LZF supplementation. Consuming a LZFO supplement for 6-months will improve visual cognitive performance. Consuming a LZFO supplement for 6-months will improve bone density. Participants will be asked to take either a LZF supplement or placebo daily for 6 months.
The design is a single blinded, dual comparative study of ultrasound versus micro-CT/LASCA in one study group. Up to a total of 140 subjects registered will be recruited. Subjects who are treatment planned for extraction of a hopeless tooth and socket augmentation with bone graft and are planned for a dental implant surgery. The socket will be evaluated before the extraction and multi-time points during healing until an implant is placed with various evaluation tools, including ultrasound.
The goal of this clinical trial is to test whether potassium citrate improves skeletal health in adults and children with chronic kidney disease. The main questions it aims to answer are: * To evaluate effects of potassium citrate treatment on bone quality and strength. * To evaluate mechanism(s) underlying the effects of potassium citrate on skeletal health. Participants will be asked to: * provide blood, urine and answer questions about health and diet three times during an 8 months period * undergo advanced bone imaging with high resolution-peripheral quantitative CT scan twice during 8 months * take study pills for 4-6 weeks at the beginning of the study to ensure safety * take either potassium citrate or placebo for 6 months during the blinded portion of the study As part of the study, there will be a run-in period followed by the placebo-controlled randomized clinical trial. Researchers will compare the bone imaging between the potassium citrate and the placebo groups at the end of the study.
The primary objective of this study is to evaluate the impact of LF111 and drospirenone (DRSP) 3.5 mg chewable tablets on bone mineral density (BMD) at the lumbar spine after 12 months (13 medication cycles) of investigation in comparison to non-hormonal contraceptive methods. Secondary objectives include further evaluating the impact of LF111 and DRSP 3.5 mg chewable tablets on BMD and bone turnover after 12 months (13 medication cycles) in comparison to non-hormonal contraceptive methods and assessing the general safety and tolerability of LF111 and DRSP 3.5 mg chewable tablets in comparison to non-hormonal contraceptive methods. Exploratory objectives include evaluating the impact of LF111 and DRSP 3.5 mg chewable tablets on body fat and lean mass after 12 months (13 medication cycles) of investigation.
This study will compare two techniques to achieve increase in ridge dimensions as a preparation for dental implants using a resorbable barrier membrane and bone particulate allogenic graft hydrated with saline or a growth factor called Recombinant Human Platelet-Derived Growth Factor (rhPDGF).
Long bone defect (LBD) is defined as a focalized loss of bone tissue in any long bone of the upper or lower extremity. Long bone defects are a complex problem, that may arise as a complication of many different pathologies, such as trauma, tumors or infection. Whereas post-traumatic defects are the largest group. Reports estimate that there are almost 4 million bone grafting procedures worldwide per year. However, limb reconstruction in the context of a bony defect is challenging and up to date there is little evidence and treatment recommendations. In a multi-national approach, the aim of this project is to set up an international, multicenter registry to gather information and details on prevalence or incidence, current treatments, complications and outcome.
The objectives of the study are to confirm safety and performance of the Zimmer Nexel Total Elbow when used in primary or revision total elbow replacement.
The objective of this study is to examine if calcium and vitamin D supplements and/or prune can prevent bone loss in postmenopausal women.
The purpose of this study is to find out if one year of romosozumab (Evenity®), a monthly injection given in the arm under the skin, prior to an infusion of zoledronic acid Reclast®, works to treat bone loss and prevent it from worsening in older women (ages 65 and older) who have osteoporosis and reside in long-term care (LTC) facilities.
