Purpose[edit | edit source]
To test for the presence of rotator cuff tears
Technique[1][2][3][edit | edit source]
Patient is seated with examiner standing behind patient. Have patient relax - palpate anterior margin of the acromion through the deltoid - while doing this grasp the patients arm with other hand at the elbow/forearm (patients elbow should be flexed to ~ 90 degrees) and bring into extension. Passively internally and externally rotate patients arm to palpate rotator cuff tendons. Presence of palpable or prominent eminence (Greater tuberosity) and/or rent (defect or 'sulcus') is indicative of full thickness tear. 1,2,3
Evidence[edit | edit source]
Wolf and Agrawal1 report Sensitivity and Specificity of 95.7% (.963) and 96.8% (.973) respectively with a positive predictive value of 95.7%, negative predictive value of 96.8% and a diagnostic accuracy of 96.3%. Cleland3 calculates a +LR of 32.0 and -LR of .04. Lyons and Tomlinson2 reported Sn of 91% (.91) and Sp of 75% (.75).
