Assessment of the Safety and the Performance of the SAGITTA EVL R Stems in Hip Arthroplasties

Completed

Conditions: Hip Arthropathy

Registration Number: NCT05153473

Lead Sponsor: Societe dEtude, de Recherche et de Fabrication

Brief Summary: Total hip arthroplasty is the preferred treatment for hip disease (primary or secondary osteoarthritis, osteonecrosis, for example) and femoral neck fractures. Revision risk factors reported when considering the main surgical approaches. Studied from the Dutch arthroplasty registry found a revision rate in hemiarthroplasty (HA) of 1.6% at 1 year and 2.5% at 5 years postoperatively. For total hip replacement (THA), the rate was 2.4% at 1 and 4.3% at 5 years postoperatively. Analyze shows that the risk factors for hemiarthroplasty were male sex, age under 80 (regardless of gender), posterolateral approach and uncemented fixation. The risk factors for HAT were exactly the same, but they found that smoking also played a role. It should be noted that age as a risk factor for revision is not a risk during the first year after the fracture, but becomes one in the years that follow.

In order to maintain compliance with the directive on medical devices (93/42 / EEC \[M5\]) and the future regulation (EU) (2017/745) relating to medical devices, SERF has set up post-market clinical follow-ups ( PMCF). This PMCF study aims to improve knowledge related to the performance, safety and benefit / risk ratio of the Sagitta EVL-R stem and to monitor patient care strategy through this clinical evaluation. Significant clinical results as well as safety must be confirmed with this patient cohort. It is important to note that this cohort reflects the specific care strategy of the University Hospital of Poitiers. Therefore, the strategy could be different between hospitals and countries.

Primary Outcome Measures

Name	Time	Method
Survival Rate of Stems	at 5 years follow-up

Secondary Outcome Measures

Name	Time	Method
Patient Satisfaction	at 5 years follow-up	The information will be collected from the patient by answering a Yes/No question at last follow-up. The following result correspond to the number of patients that have been satisfied
Functional Improvement	at 5 years follow-up	The information will be collected from both the patient through questionnaires to compare preoperatively situtation to last follow-up situtation. The patient will estimate the improvement in 3 scales: improved/unchanged/Worsen. The result present number of patient answering improved.
Pain Release	at 5 years follow-up	The information will be collected from both the patient through questionnaires to compare preoperatively situtation to last follow-up situtation. The patient will estimate the pain diminution with 2 options: Yes or No diminution of pain. Result presents the number of patient having pain diminution
