Patent ID: 8097040

Claim:
Improved humeral osteosynthesis modular prosthesis, comprising: a stem element ( 8 ) insertable within a humerus diaphyseal channel; a cup element ( 7 ) having a convex surface suitable to be introduced within a humerus glenoid cavity; a coupling element ( 9 ) having a first and a second end and comprising first coupling means ( 11 ), suitable to couple said first end to said cup element ( 7 ) and second coupling means ( 10 ) suitable to couple said first end to said stem element ( 8 ); characterised in that said cup element ( 7 ) has a concave surface suitable to contain and keep joined all the bone fragments of humerus epiphysial part, permitting vascularization and the consequent recovery of bone tissue; and said coupling element ( 9 ) has a curvature ( 6 ) corresponding to the surgical neck profile of said bone, said curvature ( 6 ) being an anatomical constant of the surgical neck of the human humerus, said coupling element comprising a cavity ( 11 ″) provided on a lower edge of said cup element ( 7 ) and of a shape memory material or titanium alloy or titanium, and an element ( 11 ′) connected at one end of the coupling element ( 9 ) and configured to engage said cavity ( 11 ″) so that said coupling element ( 9 ) is coupled to a portion of the lower edge of said cup element ( 7 ), said element ( 11 ′) having a frusto-conical shape.
