Ultrasonic Diagnosis of Tear of the Anterior Superior Labrum of the Hip

Completed

• Conditions: Acetabular Labrum Tear
• Interventions: Diagnostic Test: conventional ultrasound diagnosis of the hip joint, contrast-enhanced ultrasound, and high-resolution single hip MRI

• Registration Number: NCT04966728
• Lead Sponsor: Peking University Third Hospital

Brief Summary

The patients were divided into two groups, one group was a suspected hip joint anterior superior labrum tear, and the other group was a non-hip joint disease. The patients received conventional ultrasound diagnosis of the hip joint, contrast-enhanced ultrasound, and high-resolution single hip MRI for surgery Perform diagnostic power test for the gold standard.

Detailed Description

The patients were divided into two groups, one group was patients with suspected anterior superior labrum tear, and the other group was patients with non-hip joint diseases. Routine ultrasound diagnosis of the hip, contrast-enhanced ultrasound, and high-resolution single hip MRI were performed. For patients undergoing hip arthroscopic surgery after diagnostic occlusive treatment, the results of arthroscopic exploration are used as the diagnostic gold standard. A tear detected during the operation was judged to be positive, and a tear not detected was judged to be negative. For patients who have not undergone hip arthroscopic surgery after the closure treatment, if the MRI of the hip is performed, the MRI result is the gold standard. The diagnosis of tearing was judged as positive, and the undiagnosed tearing was judged as negative. This study was used to compare (1) the diagnostic efficacy of hip joint contrast-enhanced ultrasound and high-resolution single hip MRI in patients with suspected anterior superior labrum tear. (2) Comparison of the diagnostic efficiency of contrast-enhanced hip joint ultrasound and conventional ultrasound in patients with suspected anterior superior labrum tear. (3) In the process of judging the hip joint anterior superior labrum tear by conventional ultrasound and contrast-enhanced ultrasound of the hip joint, the consistency of repeated readings and the comparison of the consistency between readers.
