Hip replacement arthroplasties have been increasing in number as the number of patients with coxarthrosis is increasing. Prosthetic hip joints used for surface replacement with metal-metal contact are considered to be an effective choice for bone preservation. However, it has been shown that the metal-metal contact type of prosthetic hip joint could be toxic to human cells when powder from the abrasion of the Co-Cr alloy, a component of the joint, is ionized. We examined abrasion resistance and the elution of the metal ions about ceramic-coated metal pieces of the Co-Cr alloy using the Pin-On-Disk abrasion test method with a pseudo body fluid. As a result, the metal pieces with DLC coating showed the best performance in terms of their friction coefficient, abrasion resistance, and elution property of the ions. |
