Modular Dual Mobility

Mobile Bearing Hip System

• Dislocation is one of the most common causes of total hip arthroplasty failure, both in primary and revision procedures. The Modular Dual Mobility 1-4 (MDM) is designed to help prevent dislocation and achieve your operative goals of stability, longevity, and advanced fixation for fractures, primary, or revision total hip arthroplasty cases.

Key Benefits: Stability, Versatility, Longevity, Cost-Effective, Clinical Evidence, Videos

• The Stryker MDM consists of a modular cobalt-chromium insert, a large-diameter X3 polyethylene insert, and a femoral head. The highly polished, modular cobalt-chromium insert can be assembled to any Stryker acetabular cup using the Trident locking mechanism.
• Together, these components form a dual-mobility device with two points of articulation: one between the X3 polyethylene insert and the metal insert (outer tray), and the other between the X3 polyethylene insert and the femoral head (inner tray). The primary movement occurs at the inner tray, while the outer tray moves during extreme range of motion, which can minimize wear, reduce friction torque, and improve stability.
