Abstract
A femoral stem for use with an artificial hip joint assembly having helical cuts formed in the shaft thereof. The helical cuts form a restoring force spring-like shock absorbing geometry which permits the rigid metal material to grossly conform to the elastic modulus of the patient's bone. This femoral stem reduces the shock loading and attending pain associated with activities, such as standing, walking, and descending stairs, which often plague hip replacement patients.
