Product Overview

The UDM (United Dual Mobility) acetabular system is designed to help prevent dislocation by providing increased jump distance and range of motion.

The UDM acetabular system consists of a Cobalt Chrome (CoCr) acetabular cup and a mobile polyethylene liner that rotates within the cup and captures the femoral head. The inner surface of the cup is polished to allow optimal articulation between the cup and mobile liner.

UDM dual mobility cups are available with several different fixation options.

Press-fit cup

Titanium Plasma Spray PLUS coating technology designed to provide outstanding bonding strength and ‘scratch fit’ for initial stability.

Peg-fixed cup

Two pegs intended to enhance torsional stability.
The bendable flange is designed to allow extra screw fixation for superior stability.

Cemented cup

The matte surface includes horizontal and vertical grooves designed for optimal cement-implant fixation.

Multiple fixation and material options

Multiple coating, liner, and femoral head options available.
