DePuy Orthopaedics, Inc., has announced a new option for restoring hip mobility in patients who require total hip replacement: the Pinnacle® Acetabular Cup System AltrX™ hip bearing. This system provides advanced technology for recreating the natural ball and socket joint of the hip to help increase joint stability, range of motion and longevity.1,2

The AltrX polyethylene bearing is used with DePuy's exclusive Pinnacle Acetabular Cup System the only product available that provides surgeons with the option of choosing a polyethylene or metal insert for use with the same outer titanium cup that replaces the socket of the natural hip.

"The Pinnacle cup exhibited 99% survivorship at five years," said William P. Barrett, MD, Valley Orthopaedic Associates/Proliance Surgeons, Renton, WA. "And, significantly, differences between patients, surgeons, femoral stems, head size, and articulation types did not affect survival." 3

Advantages of the AltrX

The Pinnacle® AltrX™ is a polyethylene bearing liner for use in the Pinnacle Acetabular Cup System. Key benefits include:

-- Significant wear reduction: In laboratory simulations, AltrX polyethylene liners achieved a 92% wear reduction over conventional polyethylene liners, while maintaining excellent mechanical integrity and oxidative resistance.4

-- Optimized mechanical integrity: By using a unique AltraLink™ material enhancement process, AltrX liners achieve excellent mechanical toughness and oxidative resistance, which helps provide long-term durability of the implant.5

-- Based on proven technology: AltrX liners are built on the success of DePuy's Marathon™ liners,which have over six years of demonstrated clinical success.6,7

The performance of hip replacements depends on age, weight, activity level, and other factors. There are potential risks and recovery takes time. People with conditions limiting rehabilitation should not have this surgery. Only an orthopaedic surgeon can tell if hip replacement is right for a patient.
