NCT04262713

Brief Summary

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.

Outcome Measures

Primary Outcomes (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)

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

Secondary Outcomes (3)

  • Pourcentage of participants who had other prostheses failures (loosening of the prosthesis, femoral fracture, dislocation)

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

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

    Change from baseline Devane score at postoperative 4 years

  • 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

    Change from baseline weight and BMI at postoperative 4 years

Study Arms (1)

Patients implanted with Meije duo stem size 1 or 2

OTHER

Among this arm, patients that meet criteria ( weight\> 60kg and / or a long neck / varus and / or a DEVANE score ≥ 4 ) will perform hip X ray

Other: Radiographs

Interventions

Radiographs of the implanted hip with Meije duo size1 or 2 are performed in eligible patients ( Weigh\>60, Long neck stem, Varus; DEVANE score ≥ 4)

Patients implanted with Meije duo stem size 1 or 2

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • An x-ray of the hip concerned will be performed on all consenting patients, having at least one criterion of the following three during their medical history since the implantation of the hip prosthesis.
  • Weight\> 60 kg
  • DEVANE score ≥ 4
  • Long neck / varus

You may not qualify if:

  • The patient expresses his opposition to the use of his personal data
  • Patients (\<18 years old)
  • Patients unable or out of state to express their consent
  • Patient unable to speak French
  • Patient with memory impairment or cognitive impairment
  • Patient not affiliated to a social security or equivalent health coverage
