The Relationship of Metal-On-Metal Wear and Metal Ion Release in the Serum Lubricant

摘要

The results showed that metal ions released in the serum lubricant were proportional to the implant wear. Using ICPMS to measure metal ions may be an effective method to estimate implant wear than the conventional weighing method, which usually involved time-consuming cleaning and drying procedures. The similar approach may also be applied to evaluate the serum/urine ion level for the patients who use the metal-on-metal implants.
