Abstract:
1. A prosthetic ball and socket apparatus, comprising: a) a cup comprising an inner surface wherein a portion of the inner surface running from the cup's equator extending up from the equator to a northern border that runs all of the way around the inner surface at substantially a latitude such that any debris buildup caused by rubbing of a head and the inner surface of the cup against a cup liner does not unduly impair operation of the apparatus nor the patient's health to render the hip implant unsafe to implant, such portion being spherical, and a portion of the inner surface running from the northernmost points of the spherical inner surface to a north pole of the cup is hollowed out super-spherically, said cup fastened to a cup-bone; b) the head fitting inside the inner surface of the cup and contacting the spherical portion of the inner surface of the cup through the cup liner, a head-groove in said head; c) the cup liner interposed between the head and the spherical portion of the inner surface; d) a head to head-bone rod with one end fastened to a head-bone and the other end fastened to substantially a south pole of the head; e) the head groove looping approximately longitudinally allowing for walkable head rotation around the head; f) a flexible head-cable: i) fitting inside the head-groove when the head-cable is between the head and the spherical portion of the inner surface of the cup; ii) looping around a cup-cable at a point below the north pole of the inner surface of the cup; and iii) looping longitudinally allowing for walkable head rotation around the head, and g) the cup-cable: i) running parallel allowing for walkable head rotation to a portion of an outer surface of the head above a northern hemisphere of the head; ii) running perpendicularly allowing for walkable head rotation to the head-cable; and iii) fastened at each end at separate points on the super-spherical portion of the inner surface of the cup.
