Trial 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. Read more about this study

About this study

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT06744192

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. labral echo homogeneity

    Labral echo homogeneity is divided into homogeneous and heterogeneous.

    Measured: 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.

  2. 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).

    Measured: 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.

  3. labral hypoechoic cleft

    Whether to tear was divided into yes and no.

    Measured: 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.

  4. labral focal hyperechoic area

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

    Measured: 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.

  5. labral echogenicity

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

    Measured: 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.

  6. Paralabral cysts

    Absent or Present

    Measured: 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.

  7. Cortical Bone of Ilium

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

    Measured: 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.

  8. Max cross-section area of labrum

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

    Measured: 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.

  9. Hip Capsule Thickness

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

    Measured: 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.

  10. 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.

    Measured: 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.

Questions about this trial

What is this clinical trial studying?

An observational study of Acetabular Labrum Tear and Ultrasound Exams, run by Yi Mao at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

labral echo homogeneity (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.). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Dec 2024.
