Abstract:
1. A method of attaching a prosthetic femoral neck to a prosthetic femoral head, comprising: rotating a femoral neck component with respect to a femoral head component to engage a threaded interface between the femoral neck component and the femoral head component; engaging a tapered cone surface on a distal portion of the femoral neck component with a tapered bore surface on a bore of the femoral head component; lowering the temperature of at least a portion of the femoral neck component; permitting the temperature of the portion of the femoral neck component to rise such that an interference fit between the femoral neck component and the femoral head component is increased lowering the temperature of at least a portion of a third component; interconnecting the portion of the third component with a portion of at least one of the femoral neck component and the femoral stem component in a second interference fit; and permitting the temperature of the portion of the third component to rise such that the interference fit between the third component and one of the femoral neck component and the femoral stem component is increased.
