Abstract: The present invention relates to a glenoid component (100, 600, 800, 1000, 1200) for shoulder prosthesis, comprising: a glenoid coupling surface (101, 1001), adapted to be fixed to a bone and comprising a first convex portion (102) having a first outer edge (103, 1003) which defines a development plane (104, 1004); a prosthetic coupling surface (105, 1005), opposite the glenoid coupling surface (101, 1001) and adapted to house a second prosthetic component of the shoulder prosthesis, the prosthetic coupling surface (105, 1005) comprising a second portion (106) having a second outer edge (107, 1007) which defines a reference plane (108, 1008); wherein the glenoid component (100, 1000) provides a predetermined offset (109, 809, 1009) between the development plane (104, 1004) and the reference plane (108, 1008), so as to define an increased thickness of the glenoid component (100, 1000) adapted to compensate for a bone deficit. The present invention also relates to a shoulder prosthesis.

Abstract: Various embodiments of multilayer polymer films and multilayer structures with enhanced tear strength are provided. Also disclosed are processes and systems for producing the disclosed multilayer polymer films. The disclosed films comprise a first polymer that may be cross-linkable upon exposure to radiation, and a second polymer that is cleaved or broken when exposed to irradiation. Layers comprising the first polymer are referred to as bulk layers, and layers comprising the second polymer are referred to as scission layers. Scission layers are positioned between bulk layers. The bulk and scission layers may comprise one or more sublayers.
