摘要：
An artificial hip joint assembly including a ball mounted atop a supporting stem, the stem adapted to being mounted to a reconditioned end of a femur bone, with the ball adapted to seat within an acetabulum socket of a pelvic bone. An intermediate component is mounted between the ball and stem, the intermediate component incorporating force absorbing and redirecting properties at an engagement interface between the ball and stem in response to impact forces generated upon the ball by the pelvic bone. The intermediate component can be constructed of a softer material than either the ball or stem, the intermediate component can further include a sleeve exhibiting a plurality of interior threads and facilitating mounting of an exteriorly threaded end location of the stem.
