About this study

A normative development concerning the mechanical resistance tests of the the femoral stems led to contraindicate, in September 2014, to implant Meije Duo ™ femoral stems size 1 or 2 in patients weighing more than 60 kg due to an assumed risk of femoral stem breakage.

This contraindication is based on standardized mechanical tests which may have not taken into account the changes in patient weight that may occur after the intervention.

To date, investigators have not been aware of any Meije Duo ™ size 1/2 brakeage in our patients implanted with this type of prosthesis regardless of their weights before 2014. However, it is possible that some of them have had a prostheses failure and consulted another hospital. In the absence of a clinical study on this problem, investigators decided to set up a health care assessment study collecting retrospective and prospective information from our patients.

Read the detailed description

First, patients with Meije Duo ™sizes 1 or 2, who had surgery from 2007 to 2014, will be preselected on medical records.

The information notice will be sent to them by post. A period of reflection will be respected before contacting the patient to answer their questions concerning the research and its progress and obtain their oral consent to participate in the study.

After obtaining consent, investigators will enter the retrospective data collected in the medical and prospective file collected during this call.

Patients with at least one of the following criteria: weight> 60 kg and / or long neck / varus and / or DEVANE score ≥ 4, will be selected to have a hip X-ray which will be specially scheduled for the study.

This examination will tell us about the state of the prosthesis and of the underlying bone (broken stem, loosening of the implant, bone fracture, dislocation, border, etc.

It can be performed in our radiology department of the Diaconesses Croix Saint Simon hospital group or in another radiological center chosen by the patient if the latter cannot come to our hospital. In this case, a prescription for a hip X-ray will be sent to him by post to his current address as well as an information letter intended for the radiology office.

The patients who will be included in the study are implanted with Meije Duo ™ 1 and 2 between 2007 to 2014 and will all have a minimum follow-up of 4 years from the date of implantation. The maximum number of rupture complications is observed between the fourth and the eleventh year after fitting the prosthesis. All participants will therefore have a minimum of hindsight required for the evaluation of stem breaks. All of our patients will be contacted by telephone during the study period in chronological order of their previous management for obtaining consent, prospective data and for scheduling the hip radiography according to the criteria mentioned above.

What is being measured

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

  1. Pourcentage of participants who had stem (Meije DuoTM size 1 or 2) breakage occured between implantation and the study follow-up call phone.

    The number of stem breakage that occured since prostheses implantation will be collected by asking every participant during the follow-up call phone and performing hip xray to eligible ones (see above)

    Measured: Up to 4 weeks, starting from the call phone (patient consent)

Secondary outcomes (3)
  1. Pourcentage of participants who had other prostheses failures (loosening of the prosthesis, femoral fracture, dislocation)

    The number of prostheses failures that occured since the implantation will be collected by asking every participant during the follow-up call phone and by performing hip xray to eligible ones (see above)

    Measured: Up to 4 weeks, starting from the call phone (patient consent)

  2. The change of physical activity in participants from baseline (prostheses implantation) to study call-phone point time.

    With DEVANE questionnaire, investigator will assess physical activity of participants

    Measured: Change from baseline Devane score at postoperative 4 years

  3. The change of the weight and the body mass index (BMI) of the patients after the implantation of Meije DuoTM rods size 1 or 2

    Preoperative weight and BMI of particpantS will be collected from the medical file and postopeartive weight and BMI during follow up call phone

    Measured: Change from baseline weight and BMI at postoperative 4 years

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 4 inclusion and 6 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 23 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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?

Pourcentage of participants who had stem (Meije DuoTM size 1 or 2) breakage occured between implantation and the study follow-up call phone. (time frame: Up to 4 weeks, starting from the call phone (patient consent)). 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 NCT04262713, which also lists 3 linked publications.

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 23 Mar 2023.
