The U2 Revision Hip Stem™ is available in 180 mm straight and 230 mm bowed options, with a flexible choice of collared and collarless geometries. This gives surgeons a range of intraoperative fitting options to achieve optimal femoral implant fit. Other notable design features include:

  • Main Features
    • 180mm shorter straight stem design — reduces the risk of complication at the stem tip1
    • Proximal tri-wedge taper design — for excellent rotational stability and reduced potential for implant subsidence.
    • Cylindrical distal stem with polished tip — to optimize loading characteristics and decrease potential for distal-tip related thigh pain.
    • Extensive Ti plasma spray coating — enhances both proximal and distal biological fixation.
    • Ti-6Al-4V alloy — provides exceptional elasticity to minimize stress shielding and thigh pain.
    • 12/14 Morse taper

Thoughtful, surgeon-friendly design saves operation time under anesthesia by making instrument identification and access quick and easy. Trial reduction features are designed to protect the canal and secure proper fixation, through a 0.5 mm size differential between implant and broach, and a 0.7 mm size differential between implant and trial.

Designed for cemented use, the U2 Revision Hip Stemâ„¢ is indicated for use in revision of previous unsuccessful total hip replacement.
