Why is a cuboid nutcracker fracture serious?

The cuboid nutcracker fracture isn't a common fracture but it is serious because of how the bone is broken. It's been found in girls who fall while horseback riding. As their horse falls on them and their foot remains caught in the stirrup, the foot is forced away from the center of the bone, as it is usually aligned, and then there is a sort of fulcrum or pivot that causes the bone to snap. As well, there is usually more injury to the bone than just the fracture.

What makes it serious is that it needs to be treated properly to prevent long-term disabilities, allowing the patient to regain full use of the foot.
