Clinical Trial Summary

Post-marketing observational case series to analyse the functional recover and radiographic outcomes in terms of implant stability and survivorship of primary hip arthroplasty with Friendly short cemented stem.

Description:

The aim of this case series is to verify the functional recover and radiographic outcomes of primary hip arthroplasty with Friendly short cemented stem.

This is a post-marketing clinical investigation, the product on study is CE marked and used according to the intended use.

It is a national, mono-centre, prospective, observational case series on 100 patients in 1 site.

Primary endpoint is to investigate clinical progression of patients with THA with Friendly short stem from baseline to 1-year follow-up.

The secondary endpoint is to evaluate implant stability and survivorship of implants up to 5 years Follow-up.

The evaluation has an internal control because the assessment of post-treatment data is compared to baseline measurements (pre-operative clinical analysis and radiographic analysis at discharge).
