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:
* Pre-operatively: EOS radiography * Post-operatively: EOS radiograph and CT scan
Inclusion (m-3; m-1) :
* Patient information at pre-operative visit * Non-opposition of patient, family member or legal guardian, if applicable * Questionnaires and clinical examination (standard management) * EOS during anesthetic consultation
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
