Claim:
A kit for preparation of femur and ilium bones defining a hip joint and for installation of an implant body into an upper reconditioned femur end, as well as a cup shaped support to a reconditioned acetabulum defined in the ilium bone, said kit comprising: a saw for removing a damaged bulbous shaped head associated with the femur and in order to reveal a generally annular shaped receiving face which communicates an interior extending passageway; a hand held grinder exhibiting a forward-most located hemispherical shaped and rotatably driven grinder bit, a plurality of individual incising blade portions being arranged in circumferentially spaced and longitudinally extending fashion along said hemispherical shaped bit for reshaping the acetabulum socket to match a mounting surface associated with the outer socket support; said hand held grinder further having a central bit projecting from a forward most location of said hemispherical shaped bit at which said longitudinal blade portions converge, said central bit creating a hole in a base of the acetabulum, a pair of undercut machining blades being configured to incrementally actuate outwardly from said central bit for creating a successive undercut configuration within the hole formed in the reground acetabulum, and which is subsequently engaged by a projection associated with the cup; a drill template adapted to being mounted to the ilium bone and overlaying the reconditioned acetabulum, a plurality of apertures arranged in a desired pattern array within said template; and a drill insertable in succession into through each of said apertures defined in said template in order to create a pattern of drill holes in the acetabulum in alignment with additional holes established in said cup for receiving a plurality of fasteners.
