“…Historical self-report information may be affected by recall bias when elicited from respondents. However, we excluded in our analysis the subjects who presented at least one symptomatic shoulder because impairment on one shoulder could be a risk factor for the contralateral side28 ) . Finally, the original work was an observational cross-sectional study13,14,15 ) ; therefore, the sample was assessed at one time point, so no surgical confirmation or clinical follow-up for the abnormalities was found.…”

[Purpose] The aim of this study was to estimate the prevalence of abnormal shoulder ultrasonographic findings in a sample of asymptomatic women. [Subjects and Methods] A secondary analysis of a cross-sectional study was performed. We recruited 305 women (aged 18–56 years). All the subjects had a structured interview screening for self-reported symptoms and underwent a shoulder ultrasonographic examination, in which both shoulders were examined. The radiologist was blinded to the clinical history of the participants. All detectable shoulder abnormalities were collected. [Results] Of the subjects, 228 (74.75%) were asymptomatic at both shoulders, and 456 asymptomatic shoulders were analyzed. Lack of uniformity (supraspinatus, infraspinatus, subscapularis, and biceps brachii long head) was found in 28 shoulders (6.14%), 19 (4.17%) on the dominant side and 9 (1.97%) on the non-dominant side. Tendinosis (supraspinatus, infraspinatus, subscapularis, and biceps brachii long head) was found in 19 shoulders (5.32%), 12 (2.63%) on the dominant side and 7 (1.53%) on the non-dominant side. Calcification and other abnormal findings were reported. [Conclusion] The most common abnormalities were calcifications within the rotator-cuff tendons and humeral head geodes; other degenerative findings were less common.

Purpose The purpose was to 1) determine whether standard clinical muscle fatty infiltration and atrophy assessment techniques using a single image slice for patients with a rotator cuff tear (RCT) are correlated with three-dimensional measures in older individuals (60+ years), and 2) determine whether age-associated changes to muscle morphology and strength are compounded by a RCT. Methods Twenty older subjects were studied, 10 with a RCT of the supraspinatus (5M/5F) and 10 matched controls. Clinical imaging assessments (Goutallier, Fuchs scores; cross-sectional area ratio) were made for RCT subjects. Three-dimensional measurements of rotator cuff muscle and fat tissues were made for all subjects using MRI. Isometric joint moment was measured at the shoulder. Results There were no significant associations between single-image assessments and three-dimensional measurements of fatty infiltration for supraspinatus and infraspinatus. Compared to controls, RCT subjects had significantly increased fatty infiltration percentages for each rotator cuff muscle (all p≤0.023), reduced whole muscle volume for supraspinatus, infraspinatus, and subscapularis (all p≤0.038), and reduced fat-free muscle volume for supraspinatus, infraspinatus, and subscapularis (all p≤0.027). Only teres minor (p=0.017) fatty infiltration volume was significantly greater for RCT subjects. Adduction, flexion, and external rotation strength (all p≤0.021) were significantly reduced for RCT subjects, and muscle volume was a significant predictor of strength for all comparisons. Conclusions Clinical scores using a single image slice do not represent three-dimensional muscle measurements. Efficient methods are needed to more effectively capture three-dimensional information for clinical applications. RCT subjects had increased fatty infiltration percentages likely driven by muscle atrophy rather than increased fat volume. Muscle volume’s significant association with strength production suggests that treatments to preserve muscle volume should be pursued for older RCT patients. Level of Evidence Level II, diagnostic study, with development of diagnostic criteria on the basis of consecutive patients with universally applied reference “gold” standard.

“…At any given time, the prevalence of asymptomatic RCTs is greater than that of symptomatic RCTs. 2 Many RCTs also cause restriction of shoulder function. 3 Epidemiologically, their prevalence increases with age, with 54% of asymptomatic patients aged 60 years and greater having sustained either a partial or complete RCT on magnetic resonance imaging.…”

The Prevalence of Rotator Cuff Tears

Abstract: Patients treated for partial and full-thickness rotator cuff tears have a significantly higher risk of having a tear on the contralateral side and have noticeable deficits in their shoulder function regarding activities of daily living even if the tear is otherwise asymptomatic.
