Dynamic interface support established between a ceramic hip joint ball and a supporting ball stem

An artificial hip joint assembly, comprising:

• a ball mounted atop a supporting stem, said stem adapted to being mounted to a reconditioned end of a femur bone, said ball adapted to seat within an acetabulum socket of a pelvic bone;
• an intermediate component mounted between said ball and stem, said intermediate component incorporating force absorbing and redirecting properties at an engagement interface between said ball and stem in response to impact forces generated upon said ball by the pelvic bone, said intermediate component having a specified shape and size and being constructed of a softer material than either said ball or stem;
• and
• said intermediate component further comprising a sleeve exhibiting a plurality of interior threads and facilitating mounting of an exteriorly threaded end location of said stem, a groove and slot configuration established between an exterior surface of said sleeve and an interior wall surface of said ball.
