Metal on Metal Hip Replacement

Bearing Materialoptions available with different bearing surfaces. These are:

  • Metal-on-Polyethylene: The ball is made of metal and the socket is made of plastic (polyethylene) or has a plastic lining.
  • Ceramic-on-Polyethylene: The ball is made of ceramic and the socket is made of plastic (polyethylene) or has a plastic lining.
  • Metal-on-Metal: The ball and socket are both made of metal.
  • Ceramic-on-Ceramic: The ball is made of ceramic and the socket has a ceramic lining.
  • Ceramic-on-Metal: The ball is made of ceramic and the socket has a metal lining.

 

Ceramic hip implants are among the newer types of prostheses being used for hip replacement, offering greater resistant to damage and smooth movement of the joint.

Ceramic devices, by contrast, appear to cause far less inflammation and few, if any, pseudotumors. This appears true whether the device is all-ceramic, ceramic-and-metal, or ceramic-and-plastic.

Many surgeons today consider them to be an improvement over traditional metal-and-plastic implants in which the deterioration of plastic can lead to the gradual buildup of debris around the joint.
