摘要：
A reverse shoulder assembly (400), comprising: a glenoid component (100, 200, 900) comprising a glenosphere (110, 210, 910) and a glenoid plate (120, 220, 920)； and a humeral component (300, 700, 800) comprising a humeral lining (310, 710, 810) and a humeral stem (305, 705, 805), wherein the glenosphere (110, 210, 910) comprises a surface of joint (115, 215, 915) having a convex geometric shape, where the humeral lining (310, 710, 810) comprises a joint surface (315, 715, 815) having a concave geometric shape, and where the articulation surface (115, 215, 915) of the glenosphere (110, 210, 910) is adapted to articulate with the articulation surface (315, 715, 815) of the humeral lining (310, 710, 810), characterized in that the articulation surface (115, 215, 915) of the glenosphere (110, 210, 910) comprises a movement inducing element (140, 240, 940) and that the articulation surface (315, 715, 815) of the humeral lining (310, 710, 810) comprise a motion-inducing humeral lining surface (340, 750, 850), where the element in The movement inducer (140, 240, 940) and the movement inducing humeral lining surface (340, 750, 850) are sufficiently designed such that when the glenoid component (100, 200, 900) is implanted in a glenoid and When the humeral component (300, 700, 800) is implanted in a humerus, an interaction between the movement-inducing element (140, 240, 940) and the movement-inducing humeral lining surface (340, 750, 850) changes the abduction movement of the humerus relative to the shoulder blade in (a) a forward flexion movement of the humerus relative to the shoulder blade, (b) an external rotational movement of the humerus relative to the shoulder blade, or (c) a rotational movement of the humerus relative to the shoulder blade and a forward bending motion of the humerus relative to the shoulder blade, where the motion inducing element (140, 240, 940) is sufficiently dimensioned and positioned on the articulating surface (115, 215, 915) of the glenosphe
