Total Hip Arthroplasty
Conditions
Brief summary
Post-marketing clinical study,international, multi-centre, prospective, observational. The investigation will be carried out in 2 sites in Europe for a maximum total number of 160 patients.The aim of this study is to assess clinical, radiographic and subjective outcomes after hip arthroplasty with a cementless metaphyseal MINIMA short stem, define the survivorship of the implant and identify possible risk factors that may lead to failure.
