This is a prospective study of ultrasonography of the rotator cuff mechanism as an alternative to arthrography for screening rotator cuff tears. Seventy-two patients (40 men and 32 women) with possible rotator cuff tears were referred for shoulder arthrography. Before arthrography, bilateral shoulder sonography was performed by a technician under the direction of a radiologist. Arthrograms and sonograms were read separately, and a decision as to the absence or presence of a rotator cuff tear was made without knowledge of the results of the other examination. The results showed 90% sensitivity and 91% specificity, with a positive accuracy of 87%, and a negative accuracy of 93%. Ultrasonography of the rotator cuff is a noninvasive, painless, and cost-effective screening method for patients with a suspected rotator cuff tear. Author-abstract.
