Summary

This study tested whether using a computer navigation system with special pre-surgery X-rays (EOS imaging) helps surgeons place a new hip joint more accurately. 78 adults with hip osteoarthritis who needed a total hip replacement took part. The goal was to see if this technology reduces the risk of the hip dislocating after surgery and improves patients' function and quality of life.

Inclusion Criteria: * Nosologic criteria : * Primitive clinic hip osteoarthrosis * secondary secondary clinic hip osteoarthrosis : osteonecrosis of femoral head posttraumatic * Primitive radiological hip osteoarthrosis, * Indication of total hip prosthesis * Free informed and written consent, dated and signed by the patient and the investigator before any examination required by the research * Subject affiliated or beneficiary of the social security * Man or woman aged from 40 to 90 years Exclusion Criteria: * The navigation based on EOSTM imaging. requires the visualization on the EOSTM. pre-operative radiography of 6 radiological bone markers. The non-viewing of these markers is a criterion for exclusion of the study. * anaesthetic contraindication * pregnant women * Persons under the control of justice
