Shoulder MRI Findings in Adults Over 40: What Do Abnormalities Really Mean? (2026)

Imagine discovering that nearly every person over 40 has something 'wrong' with their shoulders—but 90% of them feel absolutely fine. That’s the surprising conclusion of a recent study that turned the medical world’s understanding of shoulder pain on its head. But here’s where it gets controversial: those MRI scans showing 'abnormalities' might be misleading both patients and doctors alike. Let’s unpack why this research could change how we approach shoulder pain forever.

The study analyzed 1,204 shoulders from adults over 40, revealing that 90% (1,076 shoulders) showed no symptoms at all. Of these symptom-free shoulders, a staggering 96% (1,039 shoulders) had rotator cuff abnormalities like fraying or degeneration. Meanwhile, 10% of shoulders (128) reported pain—but even here, 98% (126 shoulders) had similar structural changes. Here’s the twist: when researchers compared the two groups, common issues like tendinopathy and partial tears appeared equally often in both painful and pain-free shoulders. And this is the part most people miss: while full-thickness tears initially seemed more common in painful shoulders, statistical adjustments for other MRI findings erased this difference entirely.

So what does this mean for patients? The authors argue that terms like 'abnormalities' or 'tears' create unnecessary panic. Think about it: if nearly everyone has these changes as they age, shouldn’t we stop labeling them as 'abnormal'? The study recommends shifting language to neutral terms like 'structural alterations' or 'degeneration'—phrases that describe what’s happening without implying trauma or the urgent need for surgery. One researcher bluntly asks, 'Are we pathologizing normal aging by calling these findings abnormalities?'

Orthopedic surgeons Edgar Garcia-Lopez and Brian Feeley from UC San Francisco back this linguistic shift in an accompanying editorial. They challenge the medical community with a provocative question: How often are we ordering MRIs for shoulder pain when we shouldn’t? Their radical suggestion? For non-injury-related pain, try 2-3 months of physical therapy first. Only if symptoms persist should imaging enter the picture. But here’s the kicker: even after an MRI, treatment decisions should hinge on functional limitations—like whether you can’t lift your grandchild or reach for groceries—rather than what appears on a scan.

Could your MRI be lying to you about your shoulder pain? What if the 'tear' your doctor showed you is just another wrinkle of aging? This study forces us to confront uncomfortable truths about how we interpret imaging—and whether structural changes alone should ever dictate treatment. Share your thoughts: Should medical professionals abandon terms like 'tear' entirely, or does clearer language risk downplaying serious conditions? Let’s start a conversation that could reshape how we view pain—and aging—forever.
