Fretting corrosion due to micromotion between the femoral head and neck of hip implants is a growing concern of surgeons and patients. Debris from corrosion can lead to severe adverse effects for patients of total hip arthroplasty and reduce the lifespan of the product. Previous studies conducted by Zimmer Biomet show a connection between higher impaction force and reduced fretting corrosion and debris. This design project explored this issue and developed a training device using a current technology, a dynamic force sensor, and data analysis software for surgeons to obtain muscle memory of a 4kN strike on the head impactor, which will improve performance in the operating room and reduce the occurrence of fretting corrosion.
