Might be a CT scan slice through the protrusions(epicondyles) of the femur while the knee is bent 90°. So the lenght of the femur is coming out the back of this picture.
Or the same posture and angle bit with a normal X-ray. Though I would have expected more density in between the epicondyles. So probably CT
Ok but wtf happened to the femur on the top image?

Sounds plausible, but I’m gonna stick with my theory that someone stole the rest of their bones
