摘要： A fastener assembly can include a proximal fastener member, a distal fastener member and an internal fastener member. The proximal fastener can include a fastener head and an internal wall defining an anti-rotation feature. The distal fastener can include a proximal end defining an internal bore and an external anti-rotation feature, and a distal end defining a bone anchor. The internal fastener can be positioned in the cannulated proximal fastener and threadably coupled to the distal fastener such that the proximal end of the distal fastener is telescopically received in a distal end of the proximal fastener. Rotation of the internal fastener in a first rotational direction can telescopically retract the distal fastener into the proximal fastener so as to be adapted to compress a bone fracture. Rotation of the internal fastener in an opposite rotational direction can extend the distal fastener relative to the proximal fastener.
