Features & Benefits
Head-to-Cup Ratio
A larger femoral head diameter can improve range of motion, jump distance, and reduce the risk of dislocation.² The large diameter mobile liner is 6mm smaller than the outer diameter of the acetabular cup.
Range of Motion
The dynamic mechanism of a 3rd bearing allows the activation of the 2nd articulation with a natural single smooth movement and enhanced range of motion.

Jump Distance
By creating a larger jump distance with a larger femoral head diameter, the BI-MENTUM™ Dual Mobility System offers greater stability of the hip, helping to reduce the risk of dislocation.¹
