    • A bone fixation device comprises a rod (102) extending from a proximal end located external to the body in an operative configuration to a distal end comprising an increased diameter tip sized and shaped to be received in a subchondral layer in the operative configuration and a first bushing (112) slidably received over the rod, a distal portion of the first bushing comprising a plurality of arms separable from one another to spread radially outward from the rod as the first bushing is moved distally over the tip of the rod in combination with a cannulated element slidably received over the rod, the cannulated element sized and shaped to engage a proximal end of the first bushing, a portion thereof located external to the bone in the operative configuration so that a distally directed force applied thereto moves the first bushing distally over the rod spreading the arms radially outward.
    • 骨固定装置包括杆(102),所述杆(102)从处于外部位置的近端以可操作的构造延伸到远端,所述远端包括增大直径的尖端,其大小和形状被容纳在处于可操作构型的软管下层中,并且第一 衬套(112)可滑动地容纳在所述杆上,所述第一衬套的远端部分包括多个可彼此分离的臂,当所述第一衬套沿着所述杆的末端向远侧移动时,所述多个臂与所述杆的径向向外扩展, 插管元件可滑动地容纳在杆上,该管状元件的尺寸和形状适于接合第一衬套的近端,其一部分以可操作的构型位于骨的外部,使得向其施加的向远侧的力使第一衬套向远侧移动 杆径向向外伸展。
