DARF Research Projects

Project Name:

Mal-positioned Metal-on-Metal (MOM) Hip Replacements

 

Researcher(s): Ian Clarke, PhD; Michelle Burgett-Moreno, Thomas Halim

 

Company: FDA

 

Date(s): July 2014-June 2015

 

Classification: Hip Simulator, Metal-on-Metal

 

Steps: Proposal, Design, Test, Report

 

Parameters:

 

Results: MOM wear-rates were reasonably high and lubricant color had darkened. Cup wear patterns showed arc of potential “edge wear” was satisfactory with average 98°. Head wear patterns lacking well defined MWZ patterns

Project Name:

Vitamin E enhanced PE tested against CoCr and Delta heads

 

Researcher(s): Ian Clarke, PhD; Michelle Burgett-Moreno, Thomas Halim

 

Company: DJO

 

Date(s): November 2013-September 2015

 

Classification: Hip Simulator, Metal-on-Polyethylene, Ceramic-on-Polyethylene

 

Steps: Proposal, Design, Test, Report

 

Parameters:

 

Results: Clean test wear-rates were reasonably low, abrasive wear testing increased wear rates, but recovery phase showed wear rates returned to initial low.

 

Publications/Meetings: None at this time
