In clinical research protocols, HR-pQCT images (XtremCT Scanco, voxel size: 82 (μm3) are carried out to evaluate trabecular and cortical bone changes induced by osteoporosis and treatments. Micro-computed tomography (μ-CT) has become a standard tool for examination of trabecular and cortical bone in 3D.The purpose of this study is to evaluate the accuracy of cortical and trabecular measurements derived from HR-pQCT images with morpho...

Depth and location dependence of subchondral trabecular structure across the tibia in human osteoarthritic knee versus normal knee: a micro-CT study

Bouhadoun Hamid , Engelke Klaus , Laredo Jean Denis , Chappard Christine

Objective: To determine differences between osteoarthritic (OA) knees with normal knees for subchondral trabecular bone structure according to depth and location in the tibial plateau.Methods: In a population of 30 cadaveric left knees (18 women and 12 men, mean age: 79.1 years±8.2, range: 6390) the Kellgren-Lawrence (KL) score was determined from post mortem radiographs: OA=KL&gE;2 (n=6 women, n=5 men) and controls=KL &#8804...
