UDM™ Cup

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, cemented, press-fit and peg fixed.

UDM™ Cup

Various implant types are provided for fulfilling individual demand:
– Press-fit cup
– Peg-fixed cup
– Cemented cup

Mobile liner materials:
– XPE (Highly Crosslinked Polyethylene)
– E-XPE (Vitamin E Highly Crosslinked Polyethylene)

Titanium Plasma Spray PLUS (TPS PLUS)

The cobalt-chrome alloy offers sufficient mechanical strength and polished finish to prosthetic
articulation for all cups in the UDM system. The press-fit cup is suitable for patients with adequate
bone quality, relying on geometrical interference (press-fit) and a roughened surface (Titanium
Plasma Spray) to aide in long-term biological fixation.

Cemented Cup

For patients with severe osteopenia, irradiated acetabulum, and metabolic bone disease, the
cemented cup was designed to offer a strong solution in motion preservation with long-term
implant stability.

Mobile Liner

The large diameter of the mobile articulation component was designed to reduce potential
for dislocation by affording a greater range of motion compared to conventional fixed-bearing
acetabulum prostheses.
