Modal frequency and shape curvature as a measure of implant fixation: A computer study on the acetabular cup.
Medical Engineering & Physics(2018)
摘要
•Natural frequencies are sensitive to a bone-implant shared contact area.•Modal shapes need to be measured in order to track the natural frequencies.•Curvature of modal shapes has a great potential as a fixation indicator.
