Sharp edged internal corners usually are a little more stressed.
On the thought that it looks a bit like a femur, the mechanics of the top where there is a cranked ange into the hip joint are that the stresses are mostly derived from your body mass and they act vertically. So if you look at the structure the lattice of bone flows up in a very gentle curve from the inside bone edge up to a little above the centre of the joint, the mid point of this is usually where you see fractures.
The mechanics of your fracture are a bit similar.
?? If you (or someone) made a model of this in autocad you could do a stress analysis to look at potential points of failure and use that to guide where you put the material to transfer that load.
