Modular, adjustable, prosthetic, hip/shoulder spacer

A modular, adjustable, prosthetic hip and shoulder spacer comprising a frame and a neck positioning cylinder and wherein the longitudinal axis of said neck positioning cylinder is in a horizontal plane in relation to the vertical plane of the centerline of said frame;

• and wherein said frame is manufactured from a single piece of metallic material;
• wherein said frame comprises a neck positioning cradle unit, wherein said neck positioning cradle unit comprises a semi-circular cradle bed and further wherein said neck positioning cylinder comprises a cylinder with a first end and a second end and a circumference face;
• and further, wherein said neck positioning cylinder comprises an axle chase and an axle, wherein said axle chase traverses the full length of the longitudinal centerline of said neck positioning cylinder, and further, wherein, said axle extends through the full length of said axle chase, and further, wherein said neck positioning cylinder rotates around said axle, in a vertical plane, and further wherein said frame comprises a second, upper face and a second lower face, wherein said axle mechanically secures said neck positioning cylinder to said second upper face of said frame, and further, wherein the cylinder circumference face and the bed floor of said semi-circular bed cradle of said frame of said modular, adjustable prosthetic hip and shoulder spacer are shaped into complimentary sets of opposing, parallel groves and ridges;
• thus, when said neck positioning cylinder is positioned in said semi-circular cradle bed, said opposing grooves and ridges engage and functionally prevent said neck positioning cylinder from rotating around said axle;
• and further, wherein said axle traverses the core of said neck positioning cylinder and engages a receptacle positioned on said second upper face of said frame, thereby connecting said neck positioning cylinder to said frame.

• and further, wherein said neck positioning cylinder comprises an axle chase and an axle wherein said axle chase traverses the full length of the longitudinal centerline of said neck positioning cylinder and further said axle extends through the full length of said axle chase and further said neck positioning cylinder rotates around said axle in a vertical plane and further wherein said frame comprises a second upper face and a second lower face wherein said axle mechanically secures said neck positioning cylinder to said second upper face of said frame;
• and further, wherein modular, adjustable, prosthetic hip and shoulder spacer further comprise a system to facilitate delivery of medication to a stem implant site;
• wherein said system to facilitate delivery of medication to the stem implant site comprises a stem, wherein said stem comprises a stem leg, wherein said stem leg comprises a distal and a proximal end and wherein said proximal end comprises a threaded post, wherein said threaded post has a distal end and a proximal end and wherein said distal end of said threaded post comprises a medication supply reservoir;
• wherein the internal diameter of said medication supply reservoir is greater than the internal diameter of said stem and wherein said stem is contiguous with said threaded post;
• and further wherein said frame of said modular, adjustable, prosthetic hip and shoulder spacer comprises a base receptacle wherein the outside diameter of said proximal end of said threaded post is effectively equal in diameter to the diameter of said base receptacle and finally wherein said system to facilitate delivery of medication to to the implant site further comprises a medication input tube wherein said medication input tube is under pressure produced by external means wherein said external means are in fluid communication with said medication supply reservoir, and further, wherein said medication is transferred from said medication distribution chamber to said surgical site through a plurality of distribution ports, wherein said distribution ports traverse the walls of said medication discharge chamber, and, wherein, said system to facilitate delivery of medication to the implant site further comprises a medication input tube that is under pressure produced by external means, wherein said external means are in fluid communication with said medication supply reservoir, and further, wherein said medication is transferred from said medication distribution chamber to said surgical site through a plurality of distribution ports, wherein said distribution ports traverse the wall of said medication discharge chamber.
