Observational Study Evaluating Outcomes of Hip Arthroplasty Using Tornier Dual Mobility Acetabular Cup

Multicentre, Observational Study Evaluating the Clinical and Radiological Outcomes of Hip Arthroplasty Using the Dual Mobility Cup

The purpose of this study is to demonstrate the performance and reliability of Tornier "Dual Mobility Cup" used during primary total hip replacement or hip replacement revision surgery at least 24 months post-insertion.

The PURPOSE of this study is to demonstrate the performance and reliability of the Tornier "Dual Mobility Cup" used during primary total hip replacement or hip replacement revision surgery at a minimum of 24 months post-implantation. The primary endpoint is to determine the dislocation rate observed during post-surgical follow-up. The secondary endpoints are to assess, in the short-term, the following: clinical performance on the basis of clinical scores and hip mobility; radiological performance, particularly in terms of positioning and fixation of the implant; as well as the reliability of the implantation of this acetabular cup on the basis of any complications observed

Inclusion Criteria:

• men and women aged over 18, undergoing total hip replacement with insertion of a Dual Mobility acetabular cup between October 2010 and October 2011,
• capable of attending the 2-year follow-up visit;
• capable of understanding the information about the study and agreeing to take part in it.

Exclusion Criteria:

• patients with tumoral pathology.
