OBJECTIVE Complex vertebral confluence aneurysms remain clinically challenging despite the rapid technological advances in endovascular technology. Therefore, animal confluence aneurysm models are urgently needed for the preclinical development of related medical devices and training clinicians. This study aimed to establish canine confluence aneurysm model and evaluate hemodynamics in this mod...
BACKGROUND Vertebral size and especially cross-sectional area (CSA) are independently associated with vertebral fracture risk. Previous studies have suggested that physical activity and especially high-impact exercise may affect vertebral strength. We aimed to investigate the association between high-impact exercise at 31 and 46 years of age and vertebral dimensions in midlife. METHODS We use...
We examined the incidence of vertebral and non-vertebral fractures in published randomised clinical trials using calcitonin by parenteral injection or intranasal spray. Trials were reviewed that compared calcitonin with placebo, no therapy, or calcium with or without vitamin D, and that mentioned fracture as an outcome. Studies that compared the effect of calcitonin with other active treatments...
BACKGROUND Glucocorticoid (GC) therapy is associated with an increased risk of fractures. The main objective of this study was to determine the prevalence of undiagnosed vertebral fractures in women chronically using GC therapy for autoimmune disorders. We also determined the prevalence of non-vertebral fractures, and investigated whether factors such as quality-of-life and future fracture risk...
The incidence and prevalence of type 2 diabetes (T2D) continue to escalate at an unprecedented rate in the United States, particularly among populations with high rates of obesity. The impact of T2D on bone mass, geometry, architecture, strength, and resistance to fracture has yet to be incontrovertibly characterized because of the complex and heterogeneous nature of this disease. This study ut...
The aim of this study was to assess the usefulness of the inbred rat model for studies of genetic influences on skeletal fragility. We characterized bone mass, geometry, and skeletal biomechanics in 11 inbred strains of rats. This study showed that considerable variation exists in bone structure, areal bone mineral density (aBMD), and fragility phenotypes among inbred strains of rats. Interesti...
When neck pain is associated with pain, numbness, or weakness in the arm, shoulder, or hand, further investigation is needed as these are symptoms indicating pressure on one or more nerve roots. Evaluation necessitates a neurologic examination and imaging using an MRI/CT scan. A degenerating disc loses some thickness and is less flexible, causing inter-vertebrae space to narrow. A radiologist d...
BACKGROUND Goniometers can be used to assess shoulder ROM with reasonable accuracy, but not internal rotation. Vertebral level, as determined by the hand-behind-the-back method, is used frequently but its reproducibility is questionable. We therefore devised a new measuring tape-based method for determining vertebral level. QUESTIONS/PURPOSES We (1) compared the accuracy of a measuring tape-b...
BACKGROUND Raloxifene hydrochloride therapy reduces the risk for vertebral fractures at 3 years, but the effects on clinical vertebral fractures in the first year are not known. METHODS The Multiple Outcomes of Raloxifene Evaluation (MORE) Trial enrolled 7705 women with osteoporosis, defined by prevalent vertebral fractures and/or a bone mineral density (BMD) T score at or below -2.5, who wer...
