Filter by:The first objective is to determine the efficacy of calcium and vitamin D supplementation at doses of 1200 mg and 800 IU, respectively, to reduce the incidence of falls and fractures in non-institutionalized elderly people. The second objective is to measure and compare treatment groups (calcium and vitamin D vs placebo) as regards muscle strength and musculoskeletal function, bone mineral density, calcidiol level and treatment safety.
This randomized, placebo-controlled study will evaluate the effectiveness of the adjunctive use of teriparatide for the healing of Jones fractures.
Hypothesis: There are 5 support buttresses in the complex osteocartilaginous architecture of the nose. 1. The membranous septum; 2. The Right nasal bone; 3. The Left nasal bone; 4. The perpendicular plate of the ethmoid; 5. The vomer, vomerine groove and anterior nasal spine.
The Cohort of Swedish Men began in 1997, when all men born between 1918 and 1952 and residing in two counties in central Sweden received a questionnaire including about 350 items concerning diet and other lifestyle factors. A second questionnaire was sent out in 2008-09.
The Swedish Mammography Cohort began in 1987-1990, when 66,651 women living in two counties in central Sweden completed a mailed questionnaire that included items about their diet, parity, age at first child's birth, history of breast cancer in family, weight, height, and education. Follow-up questionnaires have been sent out in 1997 and in 2008-09.
Hypothesis: Polycaprolactone / Tricalcium Phosphate Orbital (PCL / TCP) Implant is as effective in the reconstruction of the Orbital walls as Titanium Mesh implant. In this study we will be conducting a randomised trial to compare implants made of 2 materials for Orbital reconstruction - Polycaprolactone / Tricalcium Phosphate (PCL / TCP) - Titanium Patients to be recruited : - 80 randomised equally into the 2 groups - age range: 21 - 70 - includes orbital wall defects from trauma, after osteotomies - excludes patients with Diabetes Mellitus, known allergies to polycaprolactone & its analogues, know allergies to Tricalcium Phosphate & its analogues, infections generalised & around the orbital region Trial Duration: April 2010 - March 2015 Follow up: - postoperative 1 week, 1 month, 3 months, 6 months, and 12 months - Computer Tomographic (CT) scan of Orbits immediate postoperative and at 12 months appointment
Aim of the study is to assess feasibility and safety of a public territorial radiology service for home hospitalized frail elderly patients whose health conditions discourage the transportation to hospital.
Fragility fracture is common due to global aging problem, incurring huge healthcare expenditure. The occurrence of fragility fracture is usually caused by a fall incidence of an elderly with low bone quality and poor balancing ability. Therefore, any approach to improve or retard both sarcopenia and osteoporosis will be helpful to prevent osteoporotic fracture incidence. With the intensive research on low magnitude high frequency vibration (LMHFV), many scientific evidences support the application of this biophysical modality on elderly to maintain or improve the musculoskeletal tissues in elderly. Many previous studies showed the osteogenic properties of vibration treatment and its positive effects on muscular performance and blood circulation. The investigators' previous reports also indicated that LMHFV could enhance the bone quality in spine and tibia in elderly after one-year intervention, as well as the balancing ability with high compliance. In animal studies, the application of LMHFV on fracture healing also demonstrated the significant acceleration of healing by inducing callus formation and maturation, from which upregulation of collagen I, II and BMP-2 gene expression was detected at molecular level. To date, the long-term efficacy of LMHFV on reducing fracture risks and fracture rate is, however, not available, which needs a systematic large-scale study to answer this important research question. Therefore, the hypothesis of this study is that LMHFV can maintain or enhance the performance of various tissues of the musculoskeletal system in community elderly, thus reducing the fracture risks and fracture rate. A large-scale prospective randomized clinical trial will be conducted in multiple communities to investigate the long-term effect of LMHFV on fracture rate and reduction of fracture risks in community elderly, in which multi-factorial effects, in terms of muscle and bone, on musculoskeletal system will also be evaluated. A total of 704 elderly from 28 community centres will be recruited within 1.5-year time for a 18-month LMHFV treatment, who will be assessed on the fracture risks at fixed time points while their fracture rates on the third year of this study will be regarded as primary outcome for analysis. The findings of this study will provide very useful scientific data to support the application of LMHFV for elderly. The ultimate goal is to reduce the fracture rate and the quality of life of community-living elderly.
Introduction: The orthopaedic surgeon is frequently exposed to ionizing radiation, especially during intraoperative fluoroscopy. It is expected that using a laser guided fluoroscopy technique, which should improve accuracy of radiography, should also reduce the amount of time of exposure to radiation. Finally, the literature appears controversial in this matter with no clear conclusions that could be drawn from such. Hypothesis: The test hypothesis is that the use of the laser-aiming device for fluoroscopy in several orthopaedic procedures will reduce the exposure of the patient and the surgeon to the damaging effects of radiation. The null hypothesis then states that there will be no difference in exposure to radiation between the group using the laser device and the group not using the apparatus. Methods: A prospective randomized controlled trial will be performed in which patients undergoing fluoroscopy will be randomly allocated to two groups. One group will undergo imaging with use of the device throughout the procedure and the other group will undergo radiation without the laser guided device. Number and time of exposure will be recorded for each procedure. It is of the utmost importance that the complexity of the procedures remains relatively similar. It is believed that a good measure of complexity is the surgical time. Therefore, any procedures that are statistically similar from a set mean (p > 0.05) would be included into the study. It is also important that one or two surgeons with similar expertise and years of experience perform the surgeries to avoid confounding factors. It is expected that throughout the duration of the study (8 weeks) 50-100 cases would be reported which would produce statistically significant results. The results will be analyzed by calculating confidence intervals and differences between means of continuous data and significance levels by the Student's t test. Statistical significance will be set to P < 0.05. Risks and Benefits: This study involves minimal risk. The use of the laser guide will not increase or introduce any risks other than the associated inherent surgical risks. The risks usually associated with this type of studies concern breach of confidentiality. To reduce this risk, research numbers will be assigned to subjects' data collected during the procedure, whose personal information will be found in another password-protected database. This study will help the investigators to investigate a technique that may help reduce the amount of time that a patient is exposed to radiation.
The investigators earlier have shown that treatment of patients with juvenile osteoporosis with alendronate (Fosamax) for 12 months increased the bone density without side effects. In an open label study (10 patients) and double blind, crossover study (11 patients alendronate and 11 patients placebo), the investigators have further observed that alendronate increased the bone density significantly where as placebo (calcium and vitamin D) increased only minimally. These trials were completed. Thus, a post study is designed to evaluate the current status of the bone density and fractures after the patients discontinued the alendronate treatment. No treatment is involved.
