U-Motion II Acetabular System allows orthopaedic surgeons to select an optimal couple for demanded patient populations without compromise.
Various bearing couples
Optimized Head-to-Cup Ratio, Enhanced Stability
Larger head combined with 12/14 UTF taper stem system, allowing satisfied flexion range and eliminating impingement.
Wider range of motion
Simple Setting of Liner-Cup Assembly
High Screw Angulation
Improving surgical flexibility without compromising cup fixation1.
Proven Solutions for Long-Term Stability
Advanced Acetabular System
Small cup of O.D. 56 mm accommodated with largest bearing as 40 mm diameter provides enhanced joint stability, increased ROM and lowered risk of dislocation.
