    • The invention proposes a modular reverse shoulder prosthesis (1), comprising:
      a stem (10) having a proximal taper (14) and a primary stem axis (110), the proximal taper extending from the stem about a metaphyseal axis (143), the metaphyseal axis at an angle with respect to the primary stem axis;
      a metaphysis (20; 20') having a proximal end (22), a distal end (21), an aperture (23) in the distal end configured to be placed over the proximal taper, and first interlocking means (24; 25; 25') at the proximal end having an insert axis that is eccentrically offset from the metaphyseal axis (290), the metaphysis configured for attachment to the stem at a plurality of rotational positions of the metaphysis about the metaphyseal axis; and
      a reverse insert (30; 30'; 30"), the reverse insert having a proximal end (39; 39') and a distal end (31; 31'), wherein the proximal end comprises a concave cup (38; 38') formed about a cup axis (380; 380'; 380") and configured to receive a glenosphere, and wherein the distal end comprises second interlocking means (36, 37; 36', 37'; 36", 37"),
      wherein an interface surface between the first and second interlocking means has a rotational symmetry about the insert axis (290).
    • 本发明提出了一种模块化的逆肩假体(1),包括:具有近端锥体(14)和主茎杆轴线(110)的杆(10),所述近端锥体从茎周围延伸干al轴(143)延伸, 干al轴相对于主茎轴线成一定角度; 具有近端(22)的远端(20; 20'),远端(21),远端中的孔(23),被配置为放置在近端锥体上方,以及第一互锁装置(24; 25; 25'),其具有偏离干al轴(290)偏心的插入轴线,所述干ysis构造成在干ysis端围绕干al轴的多个旋转位置处连接至杆; 和反向插入件(30; 30'; 30“),所述反向插入件具有近端(39; 39')和远端(31; 31'),其中所述近端包括凹形杯(38; 38' 形成为围绕杯轴线(380; 380'; 380“)并且构造成容纳一个大球面,并且其中该远端包括第二互锁装置(36,37; 36',37'; 36”,37“), 其中所述第一和第二互锁装置之间的界面表面具有围绕所述插入件轴线(290)的旋转对称。
