Comparison of the Restoration of Hip Biomechanical Parameters by CT Measurement Between the 3 Surgical Techniques: RSA/Minihip/THA - Hip Replacement: 3D Planning

Summary

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

Eligibility

Inclusion Criteria:
