    • Apparatus and methods for facet fusion include an insertion tool and a guide tool coupled to one another. The insertion tool has a proximal end portion and an opposite distal end portion. The distal end portion of the insertion tool is configured to retain an interbody implant, such as, for example, an inter-facet implant configured for placement between a superior facet and inferior facet of a facet joint. The proximal end portion of the insertion tool includes a handle. The guide tool includes an elongated body with a passage extending between and opening at its distal and proximal ends. A linking member extends between and adjustably connects the guide tool to the insertion tool so that the passage of the guide tool is alignable with the interbody implant retained on the insertion tool while the insertion tool and guide tool are in substantially orthogonal relation to one another.
    • 用于小面融合的设备和方法包括彼此联接的插入工具和引导工具。 插入工具具有近端部分和相对的远端部分。 插入工具的远端部分构造成保持体内植入物,例如配置为放置在小关节的上面和下面之间的面间植入物。 插入工具的近端部分包括手柄。 引导工具包括具有在其远端和近端之间延伸并在其上开口的通道的细长主体。 连接构件在引导工具与插入工具之间延伸并可调节地连接,使得当插入工具和引导工具彼此基本正交时,引导工具的通道可与保持在插入工具上的椎体间植入物对齐。
