In this study, ultrasound diagnosis was performed for patients with hip joint anterior superior labrum tear, and the final surgical observation was used as the gold standard to evaluate the diagnostic efficacy of ultrasonic measurement of the hip joint anterior superior labrum area in the diagnosis of labrum tear.

In this study, ultrasound diagnosis was performed for patients with a torn anterior superior labrum of the hip joint, and the final surgical observation was the gold standard. The control group selected patients with non-hip joint reasons to come to the ultrasound department of our hospital for diagnosis at the same time. Both the case group and the control group were included in the study at a rate of 1.1 times. This study plans to include 149 cases in the case group and 297 cases in the control group. This study was used to evaluate the diagnostic efficacy of ultrasonic measurement of the area of the anterior superior labrum of the hip in the diagnosis of labrum tears.
