INTRODUCTION FRAX®, an assessment algorithm for estimating fracture probability, has been widely used for the evaluation of osteoporosis since 2008. Its clinical use requires that osteoporotic fracture probability is established at which treatment can be recommended. OBJECTIVES The aim of the present study was to explore possible treatment thresholds for Poland. PATIENTS AND METHODS The FRA...

In this paper, the imaging of hydraulic fractures from tilt measurements is investigated with regards to model selection. The quantitative selection of the most probable model in a finite set of fracture geometry and loading is carried out using Bayes factors. The modeling error variance is also estimated during the inversion procedure. Such model selection method allows to retrieve a known lim...

A new method is used to quantify the relationships between stress field and primary fracture characters (aperture, density) in low-permeability sandstone reservoirs based on laboratory experiments and mathematical development, through which, quantitative fracture modeling is set up. Using this modeling, we can load it into the stress analysis software (Ansys 10.0) to acquire 3D palaeo stress fi...

this report presents a 3.5-year-old boy who was hospitalized for limping. medical history and physical exams were not suggestive for any definitive diagnosis. laboratory and radiographic exams did not support any specific diagnosis either. subsequently bone scan was performed and increased activity in the ankle due to cuboid fracture was incidentally observed.

Med., 1974, 113 (4), 313-317 Replicas from complementary freeze-fracture faces of the rabbit rod outer segments were examined in an electron microscope. By this method two dissimilar faces, A and B, were visualized in a disc. The A face, toward the inteadisc spa...

Polyether-ether-ketone (PEEK) is an alternative to metal alloys in orthopaedic applications. It gives significant advantages including excellent mechanical properties and non-toxicity. In this work, a set of specimens with different notched radii were selected to examine the effect of triaxial state of stress on the fracture behavior of PEEK. Fractographic analysis via scanning electron microsc...

i ntroduction: vertical root fracture (vrf) is the longitudinal fracture of the root in endodontically treated teeth. considering the limitations of two-dimensional radiographic images in detection of vrf and introduction of cone-beam computed tomography (cbct), this study was designed to find the sensitivity, specificity and accuracy of cbct and periapical (pa) radiography in detection of vrfs...

UNLABELLED Graduated compression stockings carry a potential risk of pressure, vascular and other complications. Current understanding of deep vein thrombosis (DVT) risk leaves it uncertain whether patients with hip fracture should wear stockings on both legs. OBJECTIVES To determine the association between the side of the hip fracture and the subsequent occurrence of symptomatic lower limb D...

OBJECTIVES to evaluate orthogeriatric and nurse-led fracture liaison service (FLS) models of post-hip fracture care in terms of impact on mortality (30 days and 1 year) and second hip fracture (2 years). SETTING Hospital Episode Statistics database linked to Office for National Statistics mortality records for 11 acute hospitals in a region of England. POPULATION patients aged over 60 years...

Osteoporosis is a common bone disease that increases the risk of fracture. Hip-fracture screening methods based on flnite element analysis depend segmented computed tomography (CT) images; however, current femur segmentation require manual delineations large data sets. Here we propose deep neural network for fully automated, accurate, and fast proximal from CT. Evaluation set 1147 femurs with gr...
