Some adults over 40 have shoulder pain, but nearly all have "abnormal" joints.
Breaking the findings down to shoulders instead of people, of the 1204 shoulders in the study, 1,076 (90 percent) were asymptomatic while 128 (10 percent) were symptomatic. Of the 1,076 asymptomatic shoulders, 96 percent had RC abnormalities (1,039 of 1,076) and of the 128 symptomatic shoulders 98 percent had abnormalities (126 of 128). Prevalence of tendinopathy and partial-thickness tears were similar between the symptomatic and asymptomatic groups. It initially looked like full-thickness tears were more common in the symptomatic groups, but when researchers adjusted for other factors, including additional abnormalities spotted in the MRIs, the difference between the symptomatic and asymptomatic groups vanished. Context The authors argue that the findings suggest clinicians should rethink MRI findings, changing not just how they’re used, but also how they’re explained to patients. The language in particular should change given that “abnormalities” are ubiquitous—thus normal—and shouldn’t be described in terms that indicate a need for repair, like “tear.” “While we refer to these findings as abnormalities, many likely represent normal age-related changes rather than clinically relevant structural changes,” the authors write. “Adopting more precise and less value-laden terminology—such as lesion, defect, fraying, disruption, structural alteration, or degeneration—may help reduce patient anxiety and the perceived need to do something or fix something by avoiding language that implies trauma or a requirement for repair.” In an accompanying editorial, two orthopedic surgeons from University of California, San Francisco, Edgar Garcia-Lopez and Brian Feeley, agree with the language shift and caution clinicians to proactively put MRI findings in context. They also address the glaring question of when MRIs should even be used for shoulder pain. They suggest that for pain that’s not related to an injury, clinicians should first try a couple months of watch-and-wait with rest or physical therapy to regain function. If there’s no meaningful improvement, an MRI may be warranted. But they stressed that any further decisions on treatment should be based on the patient’s history, clinical exam, and functional limitations of their shoulder—not just what’s seen on the imaging. “Of course, the findings of this study are not meant to dissuade clinicians from using MRI when appropriate, but to reinforce that the diagnosis and management of shoulder pain should be guided primarily by functional limitations,” the surgeons write.
