Metal-on-Metal Wear-Induced Tissue Necrosis

Slide 6

December 2011

The junction of the acetabular cup and femoral head is exposed to tremendous pressure during motion; this joint bears the total body weight. In the case of metal-on-metal wear, these surfaces can deteriorate, generating micro-particles of metal. These metal particles can become integrated into the soft tissue surrounding the implant, leading to necrosis. These metal particles also undergo corrosion, allowing metal ions to enter and circulate in blood serum. Now, Dr. Thomas Moyer, will continue with our discussion.
