The use of Metal on Metal bearing systems are under increasing scrutiny by Medical Regulatory Agencies because: Select one or more: O a. You should not put similar materials in contact with each other in a bearing system because they may pressure weld together O b. There is concern regarding the loss of bone density surrounding the metallic implants as a result of modulus mismatch and stress shielding O c. There is concern regarding corrosion between Cobalt-Chrome and Titanium Alloy components Od. There is concern regarding the environmental pollution associated with Cobalt extraction O e. There is concern over patient sensitisation to the metals used as the body is exposed to the ionic products of metallic wear over extended periods
