Primary objective: Evaluate femoral stem migration Secondary objective: Evaluate the performance of AMIStem H Proximal Coating at 10 years after surgery; assessment of functional recovery; radiological evaluation; reporting of complications

Scores collected:

HHS, OHS, PMA, UCLA

The main objective of the study was to evaluate the migration and performance of the AMIStem® C femoral stem at 10 years follow-up.

The primary endpoint is the measurement of femoral component migration by EBRA-FCA (The Ein Bild Roentgen Analyse-femoral component analysis, Innsbruck, Austria)

The secondary objectives of the study are:

Evaluate the performance of the AMIStem® C stem Evaluate the function of the operated hip To evaluate the quality of life To evaluate the safety of the AMIStem® C femoral stem Evaluate the postoperative stability and fixation of the hip prosthesis

The inclusion criteria are:

1. Patient with a disease (primary coxarthrosis, inflammatory arthritis of the hip, necrosis of the femoral head...) requiring the placement of a total hip prosthesis.
2. Patient who will receive an AMIStem® C cemented femoral stem.
3. Patient willing to comply with the study requirements
4. Patient who has signed the information letter agreeing to the processing of their data in the clinical evaluation
5. Patient affiliated to a social security system
6. Patients aged 18 to 85 years

The criteria for non-inclusion are:

1. Participation in biomedical research
2. Minor patients
3. Protected adult patients
4. Vulnerable persons according to article L1121-6 of the Public Health Code
5. Pregnant or breastfeeding women
6. Patients unable to formulate their non-opposition
7. Patient refusing collection of personal data

Patients with a disease (primary coxarthrosis, inflammatory arthritis of the hip, necrosis of the femoral head, etc.) requiring a total hip replacement and who will receive an AMIStem® C cemented femoral stem.

Patients will be able to participate in other non-interventional research during the study.
