Prospective ultrasound study of 90 asymptomatic adults aged 30–99, examining both shoulders to determine how age, hand dominance, and gender affect rotator cuff pathology prevalence. Ultrasound criteria were validated against unembalmed cadaver specimens before clinical application. The central question: how common are cuff tears in people who have never sought care for shoulder pain?
A 70-year-old presents with new shoulder pain after a minor fall, and the MRI shows a full-thickness supraspinatus tear. Before you plan surgery, consider: this paper tells you there is greater than a 50% chance that tear was present before the fall.
When evaluating an older patient with shoulder pain and cuff pathology on imaging, the imaging finding alone does not confirm the tear is the pain generator. Base your management on examination, functional deficit, and symptom duration — not the scan.
When counseling patients about incidental cuff findings on MRI obtained for other reasons, age-specific prevalence data from this paper gives you concrete numbers: roughly 1 in 10 adults in their 40s has a tear, rising to 1 in 2 by their 60s and 4 in 5 by their 80s.
One nuance worth knowing: the absence of a dominance effect applies to the general population, not overhead athletes. Do not use this data to dismiss cuff pathology in a competitive swimmer or pitcher.
