Objective: To emphasize the clinical importance, and quantify the degree of underreporting of vertebral fractures (VF) with and without edema on spinal magnetic resonance (MR) imaging.Methods: All spinal MR images obtained for patients ≥45 years, hospitalized from 1/6/2014 to 31/12/2015 at a single tertiary-care institution, were retrospectively reviewed to identify prevalent VFs. VF and fracture severity were classified using Genant’s method....

Hypoxia and the hypoxia-inducible factor 1alpha (Hif1alpha) are known to play critical physiological functions in endochondral bone development. However, their role in abnormal cartilage formation (chondrodysplasia) is unknown. Our goal was to test the possibility that altered oxygen homeostasis, which would result in abnormal Hif1alpha expression and activity, could lead to chondrodysplasia. This was done using matrix metalloproteinase (MMP) 9 and 13 deficient mice, which pre...
