Abstract
A method and system for monitoring impaction of a femoral component of a hip prosthesis into a femur in which impaction data generated during the impaction of the femoral component into the femur is received from at least one measurement transducer attached to the femoral component and is normalized by a data acquisition and analysis device. An impaction monitoring metric is calculated based on the normalized impaction data, and femoral component fit and stability data is then generated and output to a user interface based on the impaction monitoring metric.
