A Prospective Case-control Clinical Study of the Ultrasound Imaging Reporting and Data System for Diagnosis of Anterosuperior Acetabular Labral Tears

labral echo homogeneity

时间窗: After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants.

Labral echo homogeneity is divided into homogeneous and heterogeneous.

labral shape

时间窗: After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants.

Labral shape was divided into regular and irregular (there are potholes at the lip edge of the labrum or labrum are too full and swollen).

labral hypoechoic cleft

时间窗: After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants.

Whether to tear was divided into yes and no.

labral focal hyperechoic area

时间窗: After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants.

According to whether there is a focal hyperechoic area in the acetabular labrum, it is divided into yes and no.

labral echogenicity

时间窗: After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants.

Echo intensity can be divided into Hypoecho, Isoecho and hyperecho.

Paralabral cysts

时间窗: After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants.

Absent or Present

Cortical Bone of Ilium

时间窗: After the completion of data collection and a week of data collation, two ultrasound physicians who had undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound images of all participants.

According to the continuity of the cortical bone of the ilium, it can be divided into continuous and interrupted.

Max cross-section area of labrum

时间窗: After the data collection and a week of data collation, two ultrasound physicians undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound of all participants. Take the average value of three times.

The largest area of the anterior superior labrum of the hip.

Hip Capsule Thickness

时间窗: After the data collection and a week of data collation, two ultrasound physicians undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound of all participants. Take the average value of three times.

The anterior superior articular capsule of the hip was ultrasonically measured in the thickest area.

Thickness of Articular Cavity

时间窗: n and a week of data collation, two ultrasound physicians undergone one month of specialized reading training spent two weeks interpreting the hip labrum ultrasound of all participants. Take the average value of three times.

The ultrasound was located at the longitudinal section of the femoral neck and measured the maximum thickness of the joint cavity of the femoral neck recess.
