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

Completed

• Conditions: Acetabular Labrum Tear; Ultrasound Exams; Diagnostic Imaging; Models

• Registration Number: NCT06744192
• Lead Sponsor: Yi Mao

Brief Summary

The goal of this clinical trial is to develop an ultrasonic imaging reporting and data system for diagnosis of anterosuperior acetabular labral tears (ALT). Participants will receive a comprehensive clinical diagnosis or a hip arthroscopy to determine whether there is a torn labrum of the hip. Comparing the ultrasonographic characteristics of hip labrum in tear group and non-tear group, establishing diagnostic model is conducive to early diagnosis and differential diagnosis of this disease.

Primary Outcome Measures

Name	Time	Method
labral echo homogeneity	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	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	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	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	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	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	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	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	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	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.
