The purpose of this cross-sectional case-control study was to determine whether indices of bone structure at the 4% site of the radius discriminate women who have sustained a recent low-energy fracture of the contralateral distal radius (n = 21) from women with.Ty - jour t1 - bone strength and structural deficits in children and adolescents with a distal forearm fracture resulting from mild trauma au - farr,joshua n au - amin,shreyasee au - melton,l joseph au - kirmani,salman au . 1995/9/4 a dedicated computed tomography system was used to acquire transaxial images of the distal radius to assess trabecular bone structure in vivo we segmented trabecular bone from the marrow and soft tissue background by postprocessing the image with a region. 2015/9/1 objective: to describe cortical and trabecular volumetric bone mineral density (vbmd), bone mineral bone structure and geometric properties at the radius and tibia in adolescent endurance-trained cyclists gonzález-agüero, alex phd olmedillas, hugo phd. Osteoporosis is a metabolic bone disorder that is characterized by reduced bone mass and a deterioration of bone structure which results in an increased fracture risk since the disease is preventable, diagnostic techniques are of major importance. 1997/12/1 high resolution magnetic resonance (mr) images of the distal radius were obtained at 15 tesla in premenopausal normal, ravinder regatte, gregory chang, 7t mri of distal radius trabecular bone microarchitecture: how trabecular bone quality varies imaging.
Radius and ulna the radius and the ulna constitute as the bones of the forearm the antebrachial region, as it is clinically known, this is a projection of the lateral aspect of the distal end of the radial bone that margins the carpal articular surface superiorly. Has a structure similar to human trabecular bone with a pore diameter of 200 and 500 μm despite its natural other studies on the use of cap in the treatment of distal radius fractures are uncontrolled case series to show it is a safe material and that. 2012/12/8 bone structure at the distal radius during adolescent growth j bone miner res 200924: 1033 trabecular bone structure of the distal radius, the calcaneus, and the spine: which site predicts fracture status of. Rationale and objectives: to compare trabecular bone structure measures obtained in magnetic resonance images of the distal radius and the calcaneus as well as computed tomographic images of the spine versus bone mineral density (bmd) of.
