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

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

Sponsor

University Hospital, Lille

Enrollment

165 participants

Start Date

May 27, 2024

Study Type

OBSERVATIONAL

Conditions

coxarthrosis

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

Min Age: 18 Years
