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

labral echo homogeneity

Labral echo homogeneity is divided into homogeneous and heterogeneous.

Time frame: 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

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).

Time frame: 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 hypoechoic cleft

Whether to tear was divided into yes and no.

Time frame: 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 focal hyperechoic area

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

Time frame: 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 echogenicity

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

Time frame: 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.

Paralabral cysts

Absent or Present

Time frame: 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.

Cortical Bone of Ilium

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

Time frame: 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.

Max cross-section area of labrum

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

Time frame: 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.

Hip Capsule Thickness

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

Time frame: 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.

Thickness of Articular Cavity

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.

Time frame: 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.
