Multi-Center Comparative Trial of the ASR™-XL Acetabular Cup System vs. the Pinnacle™ Metal- on- Metal Total Hip System
A Randomized, Prospective, Comparative, Multi-Center Clinical Evaluation of the DePuy ASR™-XL Acetabular Cup System vs. the Pinnacle™ Metal- on- Metal Total Hip System Study

The primary objective of this investigation is to evaluate the clinical and radiographic outcomes of the ASR™-XL Acetabular Cup System compared to the Pinnacle™ Acetabular Cup with a 28mm or 36mm ULTAMET™ metal insert.

The purpose of this clinical investigation is to gather sufficient clinical and radiographic data to permit valid scientific comparisons between treatment and control group outcomes. The treatment group/device for this study is the ASR™-XL Acetabular Cup System, and the control group/device is the Pinnacle™ Cup System w/ the 28mm or 36mm ULTAMET™ metal liner. The study objective will be achieved by way of treatment group selection, treatment administration, and management of participating study Subjects.

Phase 4
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Subject)
Primary Purpose: Treatment
  • Osteoporosis
  • Arthritis
  • Trauma
  • Device: ASR™-XL Modular Acetabular Cup System
    The ASR™-XL Modular Acetabular Cup System treatment device is comprised of a metal acetabular cup, a unipolar femoral head and a taper sleeve adapter.
    Other Name: Acetabular cup replacement
  • Device: Pinnacle™ acetabular shell
    The Pinnacle™ shells are cementless, titanium alloy cups with Porocoat® porous coating and HA DuoFix™ coating. There are various different liners available for use with the Pinnacle™ Acetabular Cup System. For the purpose of this investigation, the CoCrMo ULTAMET® 28mm or 36 mm metal liners will be used.
