And here we have an x-ray of Millie's broken right toe on her right foot.  You can see the fracture running across the bone and slanting downwards.

This is a spiral fracture, which the internet tells me occurs when "tension is exerted on one part of the bone while compressive forces are exerted upon the other," the two parts being the part parallel to the axis of the bone and the part perpendicular to the axis.

Of course, this does not actually tell me what she did to break it, but it is, nevertheless, broken.
