Bone geometry of the hip is associated with obesity and early structural damage - a 3.0 T magnetic resonance imaging study of community-based adults

Abstract

© 2015 Teichtahl et al.; licensee BioMed Central.Introduction: The mechanism by which obesity increases the risk of hip osteoarthritis is unclear. One possibility may be by mediating abnormalities in bony geometry, which may in turn be associated with early structural abnormalities, such as cartilage defects and bone marrow lesions. Methods: One hundred and forty one older adults with no diagnosed hip osteoarthritis had weight and body mass index measured between 1990 and 1994 and again in 2009 to 2010. Acetabular depth and lateral centre edge angle, both measures of acetabular over-coverage, as well as femoral head cartilage volume, cartilage defects and bone marrow lesions were assessed wi..
