Hype™
Launched in 2010, the Hype femoral stems feature a self-locking design that is based upon the quadrangular straight femoral stem principles, a well-established concept with a proven clinical track record.1 The quadrangular implant cross-section promotes primary fixation and provides good rotational stability.2
Hype Femoral Stems provide a comprehensive solution with 4 offsets, 2 CCD angles, shortened versions, cemented/cementless and collarless/collared options to accommodate a wide range of indications all using the same streamlined instrumentation.2-3

Instrumentation
More options, less instruments
The Hype stem instruments are designed to accommodate you regardless of your surgical approach. The system has one streamlined instrument tray that is comprehensive to the entire Hype portfolio of offerings.*
*The Hype Mini stems require an additional half size instrument tray which can be eliminated by swapping the broaches in the general instrument tray
Aligned to your approach
From posterior to anterior approach, Hype stem offers a variety of broach handles.
