植入物试验
摘要：
本发明公开一种试验植入物系统和试验方法。试验植入物系统包括具有颈部(122)的柄部件(120)，该颈部包括自由端(124)和颈部纵向轴线(123)。第一试验头部(100)具有关节运动表面(102)，并且包括具有膛孔纵向轴线(106)并且可接收颈部的自由端的膛孔(108)，其中颈部纵向轴线和膛孔纵向轴线重合。该系统包括围绕纵向轴线成角度设置的第一形成物(126)和多个第二形成物(128)。第一形成物和多个第二形成物中的一者设置在颈部上，并且另一者设置在膛孔内。第二形成物中的每个可与第一形成物配合地接合，以便以不同的量限制颈部插入膛孔中的深度。
摘要（英）：

A trial implant system and method of trialling are described. The trial implant system comprises a stem component (120) having a neck (122) including a free end (124) and a neck longitudinal axis (123). A first trial head (100) has an articulating surface (102) and includes a bore (108) having a bore longitudinal axis (106) and which can receive the free end of the neck with the neck longitudinal axis and bore longitudinal axis coincident. The system includes a first formation (126) and a plurality of second formations (128) angularly disposed around the longitudinal axis. One of the first formation and the plurality of second formations is provided on the neck and the other is provided within the bore. Each of the second formations can matingly engage with the first formation to limit the depth of insertion of the neck into the bore by a different amount.
