An aiming device system that is configured to align at least one bone anchor guide to a first distal hole of an intramedullary nail can include an aiming arm that is configured to be operatively coupled to the intramedullary nail and an aiming guide. The aiming arm can define a sliding support that is elongate along a first direction. The aiming guide can include a guide body that defines at least a first bone anchor guide. The aiming guide is attached to the aiming arm such that the aiming guide is selectably movable along the sliding support, and selectably rotatable relative to the aiming arm. When the first bone anchor guide is retaining the guide sleeve, at least one of the selectable movement and selectable rotation of the guide body at least partially aligns the first bone anchor guide with the first distal hole of the intramedullary nail.經組態成對準至少一個骨錨導引到骨髓內釘的第一末端孔的瞄準裝置系統可包括經組態成組態成可操作地耦合至骨髓內釘及瞄準導引的瞄準臂。瞄準臂可定義沿第一方向伸長之滑動支撐件。瞄準導引可包括定義至少第一骨錨導引的導引體。瞄準導引附接到瞄準臂，使得瞄準導引可沿滑動支撐件選擇性地移動，並且相對於瞄準臂可選擇性地旋轉。當第一骨錨導引保持導引套管時，導引體的可選擇的移動和可選擇的旋轉中的至少一者至少部分地將該第一骨錨導引對準骨髓內釘的第一末端孔。
