PIN DM: PINNACLE® DM RSA Study
Study Details
Study Description
Brief Summary
The primary objective is to establish the mean superior cup migration of the PINNACLE® Dual Mobility Construct using model-based RSA over the first two years post-implantation. The primary endpoint is the mean vertical subsidence (Y translation, also known as superior cup migration) at 2 years as measured with RSA. Additionally, the data from this study will be compared to historical PINNACLE® data obtained in study DSJ_2018_02.
