Patent ID: 7169184

Claim:
Inverse prosthesis of the shoulder for the articulation of a humerus in a scapula of a shoulder having a glenoid cavity, comprising: an at least partly convex articulation element, including means for support and attachment of the prosthesis to said glenoid cavity, and able to articulate with an at least partly concave mating articulation element, associated with the top of said humerus, wherein said partly convex articulation element comprises a substantially hemi-spherical element having a hemi-spherical head and said means for support and attachment of said partly convex articulation element comprises a pin-type implant element made as distinct and reciprocally removable elements so that said hemi-spherical element is removably attachable onto said pin-type element, said pin-type element includes a distal end and a proximal end relative to the hemi-spherical head, wherein the substantially hemi-spherical element and said pin-type implant element are assembleable sequentially with respect to said glenoid cavity, wherein the means for support and attachment of said partly convex articulation element comprises a support element, and wherein said pin-type implant element includes a first conical portion, for coupling with said substantially hemi-spherical articulation element, and a second conical portion for coupling with a mating conical portion of the support element for functionally attaching to said glenoid cavity, said first conical portion and said second conical portion tapering in opposite directions; wherein the first conical portion has a first end and a second end, the first conical portion first end having a width wider than a width of the first conical portion second end, wherein the first conical portion tapers to narrow from the first conical portion first end to the first conical portion second end; wherein the second conical portion has a first end and a second end, the second conical portion first end having a width wider than a width of the second conical portion second end, wherein the second conical portion tapers to narrow from the second conical portion first end to the second conical portion second end; and wherein the first conical portion tapers towards the proximal end and the second conical portion tapers towards the distal end.
