Mobile Bearing Hip System

Product Features:
Trykera s versatile Mobile Bearing Hip System is designed to address stability4 , longevity5 and advanced fixation.

Stability4
a c ADM is greater than a hemisphere in some areas due to its anatomic design. ADM offers more than 88% greater jump distance than Biomet's E1 Active dual mobility bearing4,6 (Figure 2). Jump distance (mm) was measured with a 54mm shell at 45A of inclination and 20A of anteversion based upon three dimensional digital simulations*.
a c ADMa s anatomic design also addresses psoas conflict. The left and right anatomical cup shapes incorporate a psoas cutout to help provide relief between the acetabular shell rim and the iliopsoas tendon (Figure 3).
a c MDM is Strykera s Modular Dual Mobility system (Figure 4). In three dimensional simulations it also surpasses the jump distance of a traditional fixed and Biomet's E1 Active dual mobility bearing* 4,6.
*Three dimensional digital simulations of posterior horizontal dislocation demonstrate that for a given cup size the MDM and ADM designs surpass the jump height of a traditional fixed bearing and a competitive hard-on-hard device 4,6. Although resurfacing type shells have lower jump heights, they have the greatest ROM which is needed when the native femoral neck is retained 4,6.
