摘要：
A bone screw (600) comprising a proximal head (618) with a central axis (619) and an external thread (626) having a pitch p for lockingly engaging a bone plate hole (652) and a first shaft (602) extending distally from said head (618) and having the shape of a helix with a pitch P and a helix axis (603). Said head (618) and said first shaft (602) are rotatably coupled to each other, so that said shaft (602) can rotate about its axis (603) with respect to said proximal head (618).
