PURPOSE:
The purpose of this study was to verify whether arthrosonography improves diagnostic accuracy in diseases of the shoulder and provides additional information for therapeutic planning, compared with conventional sonography.
METHODS:
We prospectively studied 113 consecutive patients with chronic shoulder pain. Sonography was performed before and after arthrography, with the radiologist blinded to the results of arthrography. When a rotator cuff tear was detected sonographically, its type, location, and size were recorded; we also evaluated any changes in the subacromial-subdeltoid bursa and any abnormalities in the biceps tendon sheath. The diagnostic accuracy of conventional sonography and arthrosonography was compared with that of arthrography for rotator cuff tear. Changes in the subacromial-subdeltoid bursa and biceps tendon sheath seen on conventional sonography were also compared with those seen on arthrosonography.
RESULTS:
The sensitivity and specificity of conventional sonography in the diagnosis of rotator cuff tear were 86% (25/29) and 95% (80/84), respectively; for arthrosonography, the values were 97% (28/29) and 95% (80/84), respectively. The differences in sensitivity and specificity for the 2 sonographic techniques were not statistically significant (p > 0.05). The accuracy in localizing the tear was also not significantly different between the 2 sonographic techniques. Synovial proliferation was more easily detected with arthrosonography than it was with conventional sonography in the subacromial-subdeltoid bursa (p < 0.01) and in the biceps tendon sheath (p < 0.0001).
CONCLUSIONS:
Our preliminary results suggest that although arthrosonography was not superior to conventional sonography in the diagnosis of rotator cuff tears, it may provide a better assessment of the size of tears and additional information about synovial proliferation in the subacromial-subdeltoid bursa and the biceps tendon sheath.
