Active clinical trials for "Fractures, Compression"

Percutaneous vertebroplasty is now a common procedures of patients with acute osteoporotic vertebral compression fractures in medical units all over China, but the efficacy and essentiality of the surgery remain uncertain and is the subject of this study. This is a multiple center open-label randomised trial. Patients were randomly allocated to percutaneous vertebroplasty or conservative treatment. Because of the procedure , neither patients nor investigators were blinded. The primary outcome was pain relief at 1 month and 1 year.

Vertebroplasty in the symptomatic osteoporotic vertebral fracture has become increasingly popular. However, there have been some limitations in restoring the height of the collapsed vertebrae and in preventing the leaking of cement. In the severely collapsed vertebrae of more than two thirds of their original height, vertebroplasty is regarded as a contraindication. We tried postural reduction using a soft pillow under the compressed level. This study was undertaken to investigate the effectiveness of the combination of postural reduction and vertebroplasty for re-expansion and stabilization of the osteoporotic vertebral fractures. single level vertebral compression fracture were treated with postural reduction followed by vertebroplasty. We analyzed the degree of re-expansion according to the onset duration.

Osteoporotic vertebral compression fractures (OVCFs) are serious health problems. Transplantation of mesenchymal stem cells (MSCs) has gained considerable attention to treat osteoporosis and OVCFs because implanted healthy MSCs could be differentiated into osteoblasts and reduce the susceptibility of fractures by facilitating new bone formation. This study compares teriparatide (PTH 1-34) injection to combined treatment with Wharton's jelly-derived MSCs (WJ-MSCs) and teriparatide (PTH 1-34) in patients with OVCFs. It is a randomized, open-label, phase 2 study.

This post-market surveillance research project consists of data collection at specified time points using standard questionnaire instruments to compare pain level, mobility and function pre and post procedure using the D-Fine StabiliT® Vertebral Augmentation System and StabiliT® Bone Cement, an FDA approved product used in the standard treatment of vertebral compression fractures.

This study aimed to assess the sensory and kinematic components of the limits of stability (LOS) test in patients with vertebral compression fracture (VCF) .

The etiology and pathogenesis of osteoporosis has been extensively discussed. The relationship between bone blood circulation and the formation of bony trabeculae has been less understood. There is plenty of indirect evidence highly suggestive of the correlation between these two factors, such as: the number of blood vessels in the per unit area of the bone marrow was decreased in the osteoporotic bone, indicating the possible role of a microvascular defect in the pathogenesis of osteoporosis. Furthermore, the bone mineral density in severe arteriosclerotic patients was lower than in the less affected subjects. In a large scale epidemiologic study, diminished bone mineral density was strongly associated with increased deaths from stroke. Osteopenia was also associated with an increased risk of stroke. These reports highly suggest the effect of ischemia on bone metabolism and make the investigators more interested in further investigation. A dynamic contrast-enhanced magnetic resonance (MR) study was used recently in evaluating the blood perfusion of bone tumors. This method also has a strong correlation with the microsphere blood flow measurements. The investigator (T.F. Shih) used the dynamic MR in her recent two researches: To differentiate benign versus malignant spinal compression fractures. To evaluate the blood perfusion of non-fractured, normal-appearing vertebral bodies and find its significant correlation with aging and sex. The alterations of bone marrow perfusion are synchronous with the changes of bone mineral density. Thus, based on the investigators' previous research work, they propose to further explore the relationship between bone marrow perfusion and bone mineral density in different age groups.

This is an observational study to investigate the prevalence of osteoporotic fractures in post menopausal patients. Post menopausal patients who visit OS(orthopedic surgery) including GHs(general hospitals) and clinics will be enrolled.

Vertebral compression fractures in osteoporotic patients is a major healthcare problem. Percutaneous vertebroplasty is commonly used to restore stability of the vertebra and to alleviate pain. However, the anesthetic techniques commonly used during these procedures such general anesthesia or a combination of local anesthesia and sedation are not satisfying as they are associated either with side effects or insufficient pain reduction. This study compares the standard procedure of local anesthesia to a new technique of fluoroscopy-guided epidural anesthesia carried out by the radiologist. The investigator's hypothesis is that fluoroscopy-guided epidural anesthesia provides better pain relief during the injection of high viscosity cement and thus, reduces the need of additional intravenous analgesia by remifentanil (morphine analogue) minimizes remifentanil potential adverse effects such as respiratory depression, hypoxemia, pruritus and nausea improves working conditions and satisfaction of the radiologist improves the global satisfaction of the patient It is a monocentric, prospective, comparative and randomized study.

The purpose of this study is to investigate patient related factors that contribute to increased risk of recurrent fractures and to investigate patient adherence to prescribed anti-osteoporotic drugs.
