Abstract：
BACKGROUND:Magnetic resonance imaging (MRI) findings in asymptomatic patients have been described for hips, knees, ankles, shoulders, and intervertebral disks. No such description exists for the elbow. METHODS:MRI scans of 189 asymptomatic elbows divided into 3 groups by age (group 1, 20-39 years; group 2, 40-59 years; and group 3, ≥60 years) were evaluated for abnormalities within 13 anatomic structures using a novel classification system. RESULTS:At least 1 variation was found in all elbows. Of the 13 structures, 8 showed an increase in the prevalence and intensity of signal changes with aging, 2 remained the same, and 2 showed a decrease. One anatomic structure showed no variations in any elbow. CONCLUSIONS:Elbow MRI variations may be seen regardless of symptoms. These changes appear to increase in prevalence and intensity with age. Results from this study can be used to help guide the clinician in interpreting MRI findings of the elbow. We hope this study helps provide a contextual background for discussing MRI findings with patients and differentiating age-related variations from true pathology.
