The aim was to assess diagnostic accuracy of 15 shoulder special tests
for rotator cuff tears. DESIGN: From February 2011 to December 2012, 208
participants with shoulder pain were recruited in a cohort study. RESULTS: Among
tests for supraspinatus tears, Jobe test had a sensitivity of 88% (95% confidence
interval [CI], 80%-96%), specificity of 62% (95% CI, 53%-71%), and likelihood
ratio of 2.30 (95% CI, 1.79-2.95). The full can test had a sensitivity of 70%
(95% CI, 59%-82%) and a specificity of 81% (95% CI, 74%-88%). Among tests for
infraspinatus tears, external rotation lag signs at 0 degrees had a specificity
of 98% (95% CI, 96%-100%) and a likelihood ratio of 6.06 (95% CI, 1.30-28.33),
and the Hornblower sign had a specificity of 96% (95% CI, 93%-100%) and
likelihood ratio of 4.81 (95% CI, 1.60-14.49). CONCLUSIONS: Jobe test and full
can test had high sensitivity and specificity for supraspinatus tears, and
Hornblower sign performed well for infraspinatus tears. In general, special tests
described for subscapularis tears have high specificity but low sensitivity.
These data can be used in clinical practice to diagnose rotator cuff tears and
may reduce the reliance on expensive imaging.
