    • An elbow prosthesis comprising: a humeral component (119) comprising condyle portions (118) having humeral bushings (103) suitable to receive a hinging axle (106) along a hinging axis (112); and an ulnar component (104) comprising an ulnar bearing (105) and an ulnar body (107) configured for reciprocal coupling in a coupled condition, the condyle portions (118) and the ulnar bearing (105) being configured for reciprocal articulation about the hinging axis (112) in an articulation condition; the ulnar bearing (105) comprising an ulnar hinging hole (145); the ulnar body (107) comprising an ulnar coupling hole (143) aligned to said ulnar hinging hole (145) along said hinging axis (112) in said coupled condition, said hinging axle (106) being fixedly attachable to said ulnar coupling hole (143), the ulnar coupling hole (143) and the ulnar hinging hole (145) being further aligned with said humeral bushings (103) along said hinging axis (112) in said articulation condition, for insertion of said hinging axle (106). The elbow prothesis can be used for total elbow replacement, and allows a surgeon to intraoperatively select a linked or unlinked constraint by utilizing a connection located on the body of the ulnar and/or humeral stem. Additional modularity also allows the selection of a cemented or cementless stem as described herein. The modularity and adjustability provides a number of advantages.
    • (119),所述肱骨部件包括具有肱骨衬套(103)的髁部(118),所述肱骨衬套(103)适于沿着铰接轴线(112)接收铰接轴(106);肱骨部件 以及尺寸部件(104),其包括被配置为在耦合状态下相互耦合的尺骨支承件(105)和尺骨体(107),所述髁部分(118)和尺骨支承件(105)被配置用于围绕 铰接状态下的铰接轴(112) 尺骨承载件(105)包括尺骨铰接孔(145); 所述尺骨体(107)包括在所述联接状态下沿着所述铰接轴线(112)与所述尺骨铰接孔(145)对齐的尺骨联接孔(143),所述铰接轴(106)可固定地连接到所述尺骨联接孔 在所述铰接状态下,所述尺骨联接孔(143)和所述尺骨铰接孔(145)沿着所述铰接轴线(112)与所述肱骨衬套(103)进一步对齐,以便插入所述铰接轴(106)。 肘关节假体可以用于全肘关节置换,并且允许外科医生通过利用位于尺骨和/或肱骨躯干的连接来选择关联或非关联的约束。 额外的模块化还允许选择如本文所述的胶结或非骨水泥杆。 模块化和可调性提供了许多优点。
