Hip-Bearing System

DePuy Orthopaedics, Inc., has announced a new option for restoring hip mobility in patients who require total hip replacement: the Pinnacle^® Acetabluar Cup System Ultamet^® XL hip bearing. This modular 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 of the implant.^1,2

The Ultamet XL metal-on-metal bearing is used with DePuy’s exclusive Pinnacle Acetabular Cup System, providing 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.

DePuy Orthopaedics lists the following as key benefits:

Greater range of motion and stability. Ultamet XL bearings offer up to 159° range of motion and 20 mm of jump distance (compared with 28- and 36-mm Ultamet bearings).
Proven technology. The latest data presented at the 2007 AAOS annual meeting show that the Pinnacle Acetabular Cup System has demonstrated 99.9% survivorship at 5 years.³
Significant wear reduction. In a recent wear-simulator study, 44-mm Ultamet XL bearings reduced early wear (run-in wear) by 92% compared with traditional metal-on-metal bearings.⁴
Optimized bone preservation. By maximizing the size of the femoral head in relation to the outer diameter of the acetabular shell, Ultamet^® XL bearings allow for enhanced stability while preserving acetabular bone.
