About this study

Prospective, multicenter, non-randomized study.

Primary endpoint : to confirm the proper functioning of the device in vivo by analyzing intra and interobserver reproducibility of repeated measurements on healthy controls.

Secondary endpoint : to describe the values of pelvic inclination while standing, sitting and lying in patients with severe hip osteoarthritis before and after total hip arthroplasty

After signing the inform consent form:

For the first endpoint (, 3 healthy volunteers of different morphotypes will have one consultation comprising :

  • a medical examination
  • 10 measurements of pelvic inclination in sitting position, 10 measurements of pelvic inclination in supine position and 10 measurements of pelvic inclination in standing position, each realized per three different operators. These measurements will be carried out with navigated ultrasound.

For the secondary endpoint, 30 patients awaiting for a hip replacement surgical intervention will realized one consultation the day before the intervention, and one consultation at 2 months after surgery, each comprising :

  • a medical examination
  • 3 measurements of pelvic inclination (1 standing, 1 sitting and 1 supine). These measurements will be carried out with navigated ultrasound.

What is being measured

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

  1. Pelvic inclination measurement

    The pelvic inclination measurement corresponds to the anterior pelvic plane also known as the Lewinnek's plane; defined by the plane between both anterior superior iliac spine and the pubic symphysis.

    A Portable Ultrasound based Device is used for the Measurement of the Pelvic Tilt

    Measured: Day 0

Secondary outcomes (1)
  1. Variation of pelvic inclination before and after hip replacement

    The pelvic inclination measurement corresponds to the anterior pelvic plane also known as the Lewinnek's plane; defined by the plane between both anterior superior iliac spine and the pubic symphysis.

Questions about this trial

What is this clinical trial studying?

A study testing Pelvic inclination measurement in people with Arthroplasty, Replacement, Hip, run by University Hospital, Brest at 2 sites in France.

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

Who may be eligible to take part?

The sponsor lists 10 inclusion and 4 exclusion criteria. 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 3 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France. 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?

Pelvic inclination measurement (time frame: Day 0). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03555812, which also lists 1 linked publication.

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 3 Dec 2025.
