From: Brinjikji et al (2015) Systematic Literature Review of Imaging Features of Spinal Degeneration in Asymptomatic Populations Am J NeuroRadiol 36:811–16 Apr 2015
BACKGROUND AND PURPOSE: Degenerative changes are commonly found in spine imaging but often occur in pain-free individuals as well as those with back pain. We sought to estimate the prevalence, by age, of common degenerative spine conditions by performing a systematic review studying the prevalence o...
