In order to describe a stupid kick, I need to explain a smart one. A proper kick makes contact on the fleshy portion of the shin on either side of the bone aka blade. To do that, you need to make an up chop or a down chop by turning the hip over. In both cases, you try to kick all the way through the target. The leg is basically a bat and

over. You rotate enough to point the

|Proper form. Notice the rotation and that hips and knees are
going the same direction. This is MMA.
In all kicks with horizontal power, the hips have to torque. The harder and faster their rotation, the faster the kick is propelled. Upon contact, the body of the kicker should be sideways because knees and hips should always go in the same direction. If they don’t, not only will you lose power, but you will tear up your back and knee.
But, the absolute worst thing to do is land a kick directly on the blade of the shin. If you make contact with a fleshy portion of the body, you might be fine. But, if the blade of the shin hits something
hard, it can break and it is absolutely gross. Even if you are a seasoned fighter, it can break. If you are lucky enough not to break it, the pain alone will shock you. I’ve accidentally “clicked” shins, as I call it, with another fighter on a few occasions. The pain made me nauseated. And, we weren’t even going hard.
|Me – light tempering.|
The only exception to to that are Muay Thai fighters. They are the exception to a whole lot of rules including those of Science! They are better able to use their shin blades because they have tempered them. They roll bamboo canes up and down their shins and hit them as well. Over time, that friction and impact creates calcifications on the bones making them thicker and harder. So, unless your combatant has done tempering, that bone could break. (Even with tempering, it can. It’s just not a good practice.) A broken shin on a battle field can mean certain death. And, if the bone comes through the skin, infection could set in. Depending upon the time period of your story, that can be a mortal wound.
I’ve attached a video of Muay Thai shin tempering as well as a kick gone horribly wrong. It’s gross. You’ve been warned. It’s MMA champion Anderson Silva who landed a kick on the blade. Even with the tempering his shin has certainly had with training through the years, Silva’s power proved too powerful for his own bones.
