Abstract

PURPOSE
This study evaluated the usefulness of ultrasonography for a diagnosis of acetabular labral tear in femoroacetabular impingement (FAI).
MATERIALS AND METHODS
From March 2010 to October 2011, an ultrasonographic examination was performed in 58 patients(58 hips: 26 men and 32 women) with acetabular labral tear. The sensitivity and positive predictive value of ultrasonography were evaluated for 58 cases with acetabular labral tear confirmed by hip arthroscopy.
RESULTS
The sensitivity and positive predictive value for an acetabular labral tear using ultrasonography was 89.6% and 100%, respectively. The concordance rate of an acetabular labral tear between arthroscopy and ultrasonography was 84.6%.
CONCLUSION
Hip ultrasonography can make a significant contribution to a pathologic diagnosis and isa useful diagnostic tool for acetabular labral tears.
