I was thinking the other day about techniques that distribute force perpendicular to the bones. For example, Choy Lay Fut's Sau Chui or the Muy Thai round kick. I have seen with my own 2 eyes people break their arms or legs using these techniques.

Techniques that channel the force through the length of the bone seem to be safer because that is direction that bones are used to dealing with force. For example, a straight punch or thrust kick.

In the long term this seems to be a better long term strategy.

Thoughts?
