he Stryker Orthopaedics® UHR® Universal Head
is a leader among bipolar component designs.
Released in 1979 and patented in 1980, the UHR®
Universal Head introduced two important design
concepts to the field of orthopaedics. The first was dynamic
valgus, a neutral alignment of the head during component
loading that minimized wear on the locking mechanism.
The second was the development of a one-piece, positive
locking mechanism that provided enhanced security against
component disassembly. Both of these developments
revolutionized bipolar designs.
Today, the UHR® Universal Head retains all the same design
features and benefits, and has established effectiveness
with 20+ years of positive clinical use.1,2,3,4,5,6 No other
bipolar design can make that claim. Time proven design,
easy-to-use instrumentation and versatility regarding
femoral component selection make the UHR® Universal Head
the logical choice for your hemiarthroplasty requirements.
Dynamic Valgus Alignment
The concept of dynamic valgus
alignment was introduced by
Stryker Orthopaedics® to
provide increased head
coverage during component
loading. A two millimeter
displacement toward the dome
of the UHR® Universal Head minimizes inner bearing
articulation from occurring on the locking mechanism,
thus sparing the mechanism from undue wear.*
