    • A metatarsal implant (212) for insertion into a stem aperture (25) in a metatarsal (14) bone of a foot and to form a joint with the proximal phalanx (16) of the great toe, includes a head (226) and a stem (228). The head (226) includes an articular joint engaging surface (232) and an opposed, bone engaging surface (230). The stem (228) cantilevers away from the bone engaging surface (230), and is adapted to be inserted into the stem aperture (25). The stem (228) can have a stem axis (228A) that is at an angle (234) of between approximately 45 and 75 degrees relative to the bone engaging surface (230). The stem axis (228A) can also be at an angle (266) of between approximately 40 and 80 degrees relative to a tangential reference line (234) drawn from the articular joint engaging surface (232). In one embodiment, the stem axis (228A) is at an angle (266) of between approximately 50 and 70 degrees relative to the tangential reference line (234) of the articular joint engaging surface (232).
    • 用于插入脚的跖骨(14)中的杆孔(25)并与大脚趾的近侧指骨(16)形成关节的跖骨植入物(212)包括头部(226)和 茎(228)。 头部(226)包括关节接合表面(232)和相对的骨接合表面(230)。 所述杆(228)悬臂离开所述骨接合表面(230),并且适于插入所述杆孔(25)中。 杆(228)可以具有相对于骨接合表面(230)处于大约45度和75度之间的角度(234)的杆轴线(228A)。 茎轴(228A)也可以相对于从关节关节接合表面(232)拉出的切线参考线(234)处于大约40和80度之间的角度(266)。 在一个实施例中,杆轴线(228A)相对于关节关节接合表面(232)的切线参考线(234)处于大约50度和70度之间的角度(266)。

    • A method for guiding a saw blade (22) during preparation of a metatarsal (14) of a foot (10) for a procedure, such as to receive a metatarsal bone implant (20), includes positioning a housing (242) substantially adjacent to the metatarsal (14), coupling an aligner (38) to the housing (242), and aligning a saw guide (30) of the housing (242). The housing (242) includes the saw guide (30) for receiving and guiding the saw blade (22). The foot (10) includes one or more additional metatarsals (142), and the aligner (38) is used to align the saw guide (30) relative to the metatarsal (14) by aligning the aligner (38) to be substantially parallel to and positioned over a longitudinal axis (40) of one of the additional metatarsals (142).
    • 在准备用于手术的足部(10)的跖骨(14)的准备过程中引导锯片(22)的方法,例如接收跖骨植入物(20),包括将壳体(242)基本上邻近 跖骨(14),将对准器(38)联接到壳体(242),以及对准壳体(242)的锯条引导件(30)。 壳体(242)包括用于接收和引导锯片(22)的锯条引导件(30)。 脚部(10)包括一个或多个额外的跖骨(142),并且对准器(38)用于通过将对准器(38)对准基本上平行于跖骨(30)而相对于跖骨(14)对准锯条引导件 并且定位在所述附加跖骨(142)中的一个的纵向轴线(40)上。

    • A cutting guide (12) for guiding a saw blade (22) during preparation of a metatarsal (14) of a foot (10) for a procedure, such as to receive a metatarsal implant (20), includes a housing (242) and an aligner (38). The housing (242) is adapted to be positioned substantially adjacent to the metatarsal (14). The housing (242) includes a saw guide (30) for receiving and guiding the saw blade (22). The aligner (38) is coupled to the housing (242). The foot (10) includes one or more additional metatarsals, and the aligner (38) is used to align the saw guide (30) relative to one of the additional metatarsals. The aligner (38) can extend substantially perpendicular to the saw guide (30). Additionally, the aligner (38) can be used to be substantially aligned with a longitudinal axis (40) of one of the additional metatarsals. The cutting guide (12) can further include a handle (244) that is secured to the housing (242). Further, the aligner (38) can be a bar that is coupled to the handle (244) and that extends substantially perpendicular to the handle (244).
    • 用于在准备用于诸如接收跖骨植入物(20)的过程的足部(10)的跖骨(14)期间引导锯片(22)的切割引导件(12)包括壳体(242)和 对准器(38)。 壳体(242)适于基本上邻近跖骨(14)定位。 壳体(242)包括用于接收和引导锯片(22)的锯条引导件(30)。 对准器(38)联接到壳体(242)。 脚(10)包括一个或多个额外的跖骨,并且对准器(38)用于相对于附加跖骨之一对准锯导件(30)。 对准器(38)可以基本上垂直于锯条引导件(30)延伸。 另外,对准器(38)可以用于与附加跖骨之一的纵向轴线(40)基本对齐。 切割引导件(12)还可以包括固定到壳体(242)的手柄(244)。 此外,对准器(38)可以是联接到手柄(244)并且基本上垂直于手柄(244)延伸的杆。
