U-Motion II⁺™







TPS PlusTM Surface Coating
U-Motion II+ Acetabular System utilizes the new Ti plasma spray plus (TPS Plus) coating technology to achieve a greater surface roughness (Ra).
The rough surface of implant provides scratch fit for initial stability and has been shown to reduce micromotion, both effects contribute to long term fixation of the implant

 Increase Surface Roughness 



Optimized Head-to-Cup Ratio Provides Excellent ROM

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 fixation.3





Bearing Options: Metal and Ceramic on XPE Liner

U-Motion II+ Acetabular System allows surgeons to select either metal on XPE or ceramic on XPE bearing option.
