Abstract
To determine the value of ultrasonography (US) in the detection of Hill-Sachs lesion of the humerus in comparison with double-contrast computed tomographic arthrography (CTA) and with arthroscopy. US and CTA were performed on 92 patients, 86 of whom subsequently underwent arthroscopy. The findings of US, CTA and arthroscopy in these 86 patients in the diagnosis of Hill-Sachs lesion were analyzed. In the detection of Hill-Sachs lesion US showed a sensitivity of 91% (21 of 23), a specificity of 95% (60 of 63) and an accuracy of 94% (81 of 86) when compared with CTA, and a sensitivity of 94% (18 of 19), specificity of 91% (61 of 67) and accuracy of 91% (79 of 86) when compared with arthroscopy. In only 2% (2 of 86) of patients was there reduced visualization because of restriction of movement. Hill-Sachs lesion and its relationship to the humeral head can be reliably diagnosed with US.
