Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

A

ASR™-XL Modular Acetabular Cup System stem

Group Type ACTIVE_COMPARATOR

ASR™-XL Modular Acetabular Cup System

Intervention Type DEVICE

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.

B

Pinnacle™ acetabular shell, with a 28mm or 36mm ULTAMET® metal liner, and a 28mm or 36mm Articul/eze M head.

Group Type ACTIVE_COMPARATOR

Pinnacle™ acetabular shell

Intervention Type DEVICE

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.
