Sonographic Evaluation of Anterosuperior Hip Labral Tears With Magnetic Resonance Arthrographic and Surgical Correlation

Abstract

When the arthroscopic results were used as the reference standard, our preliminary study revealed that sonography managed to show anterosuperior labral abnormalities, although it had a lesser diagnostic ability than MR arthrography in diagnosing anterosuperior labral tears. Additional investigations including larger numbers of patients are required to determine whether sonography can be an alternative or adjunctive imaging technique for diagnosis of hip labral tears, especially in patients who decline or are unable to undergo MR arthrography.
