MRI findings predict shoulder stiffness for rotator cuff tears
Leesburg - Researchers conducted a study to evaluate the relationship between stiff shoulder in patients with a full-thickness rotator cuff tear and MRI findings and found that two MRI findings--joint capsule oedema and thickness at the axillary recess, specifically--proved useful in predicting stiff shoulder in patients with rotator cuff tears, according to an article in the American Journal of Roentgenology (AJR).
Studying 106 patients with small to large (< 5 cm) full-thickness rotator cuff tears, in addition to joint capsule oedema and thickness in the axillary recess, Yoon Yi Kim of Korea's Veterans Health Service Medical Center assessed obliteration of the subcoracoid fat triangle, fatty degeneration of the torn rotator cuff muscle, and degree of retraction.
Tear size and location were determined by MRI findings and operative report, while associations between MRI findings and preoperative passive range of motion (ROM) were evaluated with simple and multiple linear regression analyses and proportional odds logistic regression analysis.
