    • An apparatus for treating a bone comprises an implant to be received within the bone, including a plurality of bores extending therethrough and a cavity formed therewithin, each of the bores being dimensioned to receive a bone fixation element and a plurality of inserts receivable in the cavity. Each insert includes an opening extending therethrough and configured to align with a corresponding bore. Each insert is movable between a resting configuration in which an opening width is smaller than a width of a bone fixation element inserted therethrough and a stressed configuration in which the opening width is expanded to a width greater than that of the bone fixation element in combination with a compression member movable into the cavity to apply a force moving the inserts from the resting configuration to the stressed configuration, withdrawal thereof reducing the force and permitting a return to the resting configuration.
    • 用于治疗骨的装置包括待接收在骨内的植入物,其包括延伸穿过其中的多个孔和在其中形成的腔,每个孔的尺寸被设计成接收骨固定元件和可容纳在腔中的多个插入物 。 每个插入件包括延伸穿过其中并被构造为与对应的孔对准的开口。 每个插入件可以在其中开口宽度小于插入其中的骨固定元件的宽度的静止构型和应力构型之间移动,其中开口宽度被扩展到宽于大于骨固定元件的宽度的宽度 压缩构件可移动到空腔中以施加将插入件从静止构型移动到应力构型的力,其撤回减小了力并允许返回静止构型。
