A common complication post hip replacement is hip dislocation or hip instability which can lead to the hip implants being revised. A new generation of Dual Mobility hips was designed to minimize hip dislocation/hip instability and polyethylene wear thus increasing the longevity of the hip prosthesis and reducing the number of re-operations for a patient. In this study we will be assessing 2 dual mobility hips manufactured by Stryker Orthopaedics Inc. The ADM and the MDM.
Hip replacement is a procedure in which the hip joint is replaced by a prosthetic implant or prosthesis. Post op hip dislocation or hip instability is a common complication which can lead to the hip implants being revised. There are many types of hip prostheses manufactured with the aim of prolonging longevity of the prosthesis and minimizing postoperative complications. One of these is a new generation of dual mobility hip manufactured by Stryker Orthopaedics. The Anatomic Dual Mobility (ADM) and the Modular Dual Mobility (MDM) were designed to minimize hip dislocation/hip instability and polyethylene wear thus increasing the longevity of the hip prosthesis and reducing the number of re-operations for a patient. In this study we will be assessing the outcome of the ADM and MDM hip system.
