Key result
Rotator cuff tears were associated with cystic changes at the attachment of the supraspinatus and subscapularis tendons (28% vs 0% in intact cuffs), whereas bare bone cysts were related to aging.
Why the study?
Does MR imaging reveal a relationship between cystic changes of the humeral head and rotator cuff tears in patients with painful shoulders?
Population
134 patients with 140 painful shoulders
Comparison
MR imaging vs Shoulders with versus without rotator cuff tears
Design
Cross-sectional

Cystic changes at tendon attachments on MRI may aid rotator cuff tear identification; leaves open diagnostic utility pending prospective validation.
Observational (n=134)
Does MR imaging reveal a relationship between cystic changes of the humeral head and rotator cuff tears in patients with painful shoulders?
Absolute Event Rate: 28% vs 0%
Cystic changes at the attachment of the supraspinatus and subscapularis tendons on MRI are highly specific for rotator cuff tears, whereas cysts in the bare bone area are age-related.
Sano et al. (1998) conducted an observational in Painful shoulders (n=134). Rotator cuff tears vs. Intact rotator cuff was evaluated on Cystic changes at the attachment of the supraspinatus and subscapularis tendons. Rotator cuff tears were associated with cystic changes at the attachment of the supraspinatus and subscapularis tendons (28% vs 0% in intact cuffs), whereas bare bone cysts were related to aging.
