Abstract
PURPOSE: To compare shoulder ultrasonography with arthroscopy for detecting specific rotator cuff tears. METHODS: 96 shoulders in 56 men and 34 women aged 28 to 65 (mean, 42) years with rotator cuff problems underwent a shoulder ultrasonography by a single radiologist, and then a shoulder arthroscopy by a single surgeon. The ultrasonographic and arthroscopic findings were compared with regard to tendon-specific tears and disparities in diagnosis. RESULTS: For detection of supraspinatus tendon tears, ultrasonography attained a sensitivity of 89%, specificity of 43%, positive predictive value of 76%, and negative predictive value of 100%. For detection of subscapularis tendon tears, ultrasonography attained a sensitivity of 30%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 78%. Sensitivity, specificity, and predictive values were good in larger full-thickness tears, but were significantly reduced in sub-centimetre and partial-thickness tears, particularly of the subscapularis tendon. CONCLUSIONS: Surgeons should be aware of the potential disparities between ultrasonographic and arthroscopic findings and be prepared to adjust the surgical procedure during arthroscopy.
