The study will analyze hip biomechanical parameters using EOS radiographic measurements pre- and post-operatively (3 months) and post-operatively (3 months) CT scans after total hip replacement (THR), neck-preserving THR of the Minihip type or hip resurfacing (HR). Clinical results will be assessed at 3 months and 1 year after surgery.
To this end, two types of examination are carried out, both of which are used in current practice:
Inclusion (m-3; m-1) :
Follow-up visit (m+3):
- Post-operative follow-up consultation EOS and CT scan (1 week prior to visit) + questionnaire and clinical examination
Follow-up visit (m+12):
- Post-operative check-up, questionnaire and clinical examination

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| total hip arthroplasty (THA) | Standard THA, the head and neck of the femur are cut. |
| |
| Total hip prosthesis with femoral neck preservation | A total hip replacement is performed, but the neck of the femur is preserved and the head of the femur is cut off. |
| |
| Hip resurfacing | the head and neck of the femur are preserved. |

| Measure | Description | Time Frame |
|---|---|---|
| Comparing the restoration of femoral hip offset between hip resurfacing procedures (HRP), THA and Minihip-type neck-preserving total hip arthroplasty. | The primary endpoint will be the difference between the native femoral offset, measured on the healthy contralateral hip, and the postoperative femoral offset of the operated hip. The offset is the distance in millimeters between the axis of the femoral shaft and the center of the femoral head. | It will be measured using CT scans at 3 months post-op for each hip. |
| Measure | Description | Time Frame |
|---|---|---|
| Compare the anatomical restoration of frontal and axial parameters between the 3 types of intervention (PTH, Minihip and RSA). | Difference between the contralateral healthy hip and the operated hip at 3 months post-op of the following parameters:

| Compare clinical outcomes and patient satisfaction between the 3 procedures (PTH, Minihip and RSA). | Variations between the pre-operative and post-operative 3-month and 1-year periods in the following clinical parameters: Oxford, Harris, PMA, Devane, UCLA, Forgotten Joint Score Hip (FJS hip), joint amplitudes, ILMI clinical estimate (in cm) - Patient satisfaction: measured using a 4-item MCQ (dissatisfied, not very satisfied, satisfied, very satisfied) at 3 months (early recovery) and 1 year (definitive recovery). | 3 months then 1 year post-op |
| Correlate restoration of hip femoral offset and patient functional outcome at 3 months. | Offset restoration, defined as the difference between the native femoral offset, measured on the healthy contralateral hip, and the postoperative femoral offset of the operated hip. - Patient functional outcome, defined by the Oxford score. | 3 months post-op |
