Glenoid component (100, 600, 1200) for shoulder prosthesis, comprising: - a glenoid coupling surface, adapted to be fixed to a bone and comprising a first convex portion having a first outer edge which defines a development plane; - a prosthetic coupling surface, opposite said glenoid coupling surface and adapted to house a second prosthetic component of said shoulder prosthesis, said prosthetic coupling surface comprising a second portion having a second outer edge which defines a reference plane; wherein said glenoid component provides a predetermined offset between said development plane and said reference plane, wherein said predetermined offset is configured to vary a longitudinal distance along the perimeters of said first outer edge and of said second outer edge, defining an angle (α) between said development plane and said reference plane, said predetermined offset defining an increased thickness of said glenoid component (100, 600, 1200) for compensating a bone deficit, wherein said first outer edge of said glenoid coupling surface is substantially circular, and wherein said second outer edge of said prosthetic coupling surface is substantially circular, characterized in that said glenoid component comprises a substantially truncated cone-shaped glenoid coupling element, projecting from said glenoid coupling surface and being adapted to be coupled to a bone pin of said shoulder prosthesis, said glenoid coupling element developing along an axis which is substantially perpendicular to said reference plane, and in that said substantially circular first outer edge and said substantially circular second outer edge are configured so as to allow an orientation of the glenoid component (100, 600, 1200) in a continuous way, covering all types of bone defects over 360°. - a glenoid coupling surface, adapted to be fixed to a bone and comprising a first convex portion having a first outer edge which defines a development plane; - a prosthetic coupling surface, opposite said glenoid coupling surface and adapted to house a second prosthetic component of said shoulder prosthesis, said prosthetic coupling surface comprising a second portion having a second outer edge which defines a reference plane; wherein said glenoid component provides a predetermined offset between said development plane and said reference plane, wherein said predetermined offset is configured to vary a longitudinal distance along the perimeters of said first outer edge and of said second outer edge, defining an angle (α) between said development plane and said reference plane, said predetermined offset defining an increased thickness of said glenoid component (100, 600, 1200) for compensating a bone deficit, wherein said first outer edge of said glenoid coupling surface is substantially circular, and wherein said second outer edge of said prosthetic coupling surface is substantially circular, characterized in that said glenoid component comprises a substantially truncated cone-shaped glenoid coupling element, projecting from said glenoid coupling surface and being adapted to be coupled to a bone pin of said shoulder prosthesis, said glenoid coupling element developing along an axis which is substantially perpendicular to said reference plane, and in that said substantially circular first outer edge and said substantially circular second outer edge are configured so as to allow an orientation of the glenoid component (100, 600, 1200) in a continuous way, covering all types of bone defects over 360°.
