Implants, systems and methods of using the same

An orthopedic implant assembly, comprising:

• a baseplate, said baseplate having a cylindrical shape, an upper surface, and a lower surface, said baseplate further comprising a central bore disposed from said upper surface to said lower surface, said baseplate further comprising a plurality of discrete arcuated keels extending from a bottom surface of said baseplate, said central bore having a proximal interior threaded section and a distal non-threaded section;
• a central screw, said central screw having a central axis, a proximal non-threaded section having a cylindrical shape, and a distal threaded section, said central screw further comprising a proximal head portion, said head portion having a surface area that increases in a direction opposite said threaded portion, said central screw further comprising a recess having a proximal section for engaging a torque device, a central threaded portion, and a distal non-threaded portion, said recess disposed through said proximal head, said central screw slidingly disposed through said central bore of said baseplate, wherein a diameter of said head is greater than a diameter of said non-threaded section of said central bore of said baseplate such that said central screw is captured by said baseplate central bore, said central screw suitable for threading into a bone;
• a modular taper, said modular taper having a tapered cylindrical shape, a distal threaded portion and a proximal recess for engaging a torque device, and a central bore, said modular taper threadedly connected to said central bore of said baseplate;
• a glenosphere, said glenosphere having a hemispherical shape and a central bore having a distal tapered portion, a central threaded portion, and a proximal cylindrical portion, said glenosphere disposed atop said modular taper such that an exterior of said modular taper and the distal tapered portion of said glenosphere bore form a mechanical taper connection;
• and
• a post, said post having a cylindrical post proximal head having a diameter and a proximal recess for engaging a torque device, said post further comprised a central post portion having a diameter smaller than the diameter of said post proximal head, said post further having a distal post portion having a diameter smaller than the diameter of said post proximal head, said post further comprising an exterior threaded portion, said exterior threaded portion disposed along a portion of said post between said central post portion and said distal post portion, said post disposed through said central bore of said glenosphere and said central bore of said modular taper, said post further disposed into and threadedly connected to said recess of said central screw.

An orthopedic implant assembly system, said implant assembly system comprising:

• at least one baseplate having a cylindrical shape, an upper surface, and a lower surface, said baseplate further comprising a central bore disposed from said upper surface to said lower surface, and a plurality of peripheral bores disposed around said central bore;
• said baseplate further comprising a plurality of discrete arcuated keels extending from a bottom surface of said baseplate, said central bore having a proximal interior threaded section and a distal non-threaded section;
• a plurality of central screws, each screw of said plurality of central screws having a central axis, a proximal non-threaded section having a cylindrical shape, and a distal threaded section, said central screws further comprising a proximal head portion, said head portion having a surface area that increases in a direction opposite said threaded portion, said central screws further comprising a recess having a proximal section for engaging a torque device, a central threaded portion, and a distal non-threaded portion, said recess disposed through said proximal head, said central screws slidingly disposed through said central bore of said baseplate, where a diameter of said head is greater than a diameter of said non-threaded section of said central bore of said baseplate such that said central screws are captured by said baseplate central bore, said central screws suitable for threading into a bone;
• at least one peripheral compression screw, said peripheral compression screw disposed through one of said peripheral bores, said peripheral screw suitable for threading into a bone;
• at least one modular taper, said modular taper having a tapered cylindrical shape, a distal threaded portion and a proximal recess for engaging a torque device, and a central bore, said modular taper threadedly connected to said central bore of said baseplate;
• a plurality of glenospheres, each glenosphere of said plurality of glenospheres having a hemispherical shape and a central bore having a distal tapered portion, a central threaded portion, and a proximal cylindrical portion, said glenospheres disposed atop said modular taper such that an exterior of said modular taper and the distal tapered portion of said glenospheres bore form a mechanical taper connection;
• and
• at least one post, said post having a cylindrical post proximal head having a diameter and a proximal recess for engaging a torque device, said post further comprised a central portion having a diameter smaller than the diameter of said post proximal head, said post further having a distal portion having a diameter smaller than the diameter of said post proximal head, said post further comprising an exterior threaded portion, said exterior threaded portion disposed along a portion of said post between said central post portion and said distal post portion, said post disposed through said central bore of said glenospheres and said central bore of said modular taper, said post further disposed into and threadedly connected to said recess of said central screws.
