Left: fracture surface of the main fragment. a Possible origin of the ceramic fracture. b Secondary crack originated at the level of the proximal end of the neck taper. c Secondary crack originated at the level of the proximal end of the neck taper following to the first shift of the taper. d Secondary crack originated at the level of the proximal end of the neck taper following to the second shift of the taper (note: the tip of the taper impacts to the top of the head bore). EDX spectrum revealed that particles on the fracture surface are made of Ti-alloy
