Damage initiation sites in osteoporotic and normal human cancellous bone.
Using a finite element (FE) method called biomechanical stereology, Wang et al. previously reported increased microcrack formation and propagation in bone samples from patients with a history of osteoporotic fracture as compared to normal subjects. In this study, we re-analyzed the data from Wang's report to determine the microscopic differences between bone tissue from osteoporotic patients an...
متن کاملMetabolic studies of human bone in vitro. I. Normal bone.
It has long been apparent that the key to understanding the pathophysiology of metabolic bone disease lies in understanding human skeletal physiology at the tissue level. Although some gross and microscopic structural disturbances (1, 2) and changes in total skeletal mineral content (3) have been correlated with certain types of metabolic bone disease, rates of accretion and resorption have bee...
متن کاملBone mineral densities in normal Bangladeshi women
fracture. Several chronic medical conditions, medications, and life style factors affect bone mineral accrual. This study aims to evaluate the bone mineral densities and hip axis lengths in the local population. Materials and Methods: 336 normal Bangladeshi women age ranges 20 to 70 years had evaluation of their bone mineral densities (BMDs) by means of dual X-ray absorptiometry (DXA). Results:...
متن کاملBone mineral content of the lumbar spine in normal and osteoporotic women: cross-sectional and longitudinal studies.
1. Bone mineral content of the second, third and fourth lumbar vertebrae was determined in normal women and women with clinical osteoporosis by using dual-photon (153Gd) absorption. 2. A cross-sectional study of 70 normal (aged 19-88 years) showed a bone loss of 44% from the age of around 34 years throughout life. 3. Longitudinal data from 59 normal women confirmed that the vertebral bone loss ...
متن کاملHistomorphometric Analysis of Newly-formed Bone Using Octacalcium Phosphate and Bone Matrix Gelatin in Rat Tibial Defects
Background: Repair of bone defects is challenging for reconstructive and orthopedic surgeons. In this study, we aimedto histomorphometrically assess new bone formation in tibial bone defects filled with octacalcium phosphate (OCP),bone matrix gelatin (BMG), and a combination of both.Methods: A total of 96 male Sprague Dawley rats aged 6-8 weeks weighing 120-150 g were randomly allocatedinto thr...
