Fractures occur when the fist hits a solid area at the wrong time in the wrong way, under those circumstances it doesn't matter that much WHERE on the knuckles you hit.
Boxers tend to fracture that area because of hooks or looping punches rather than straight shoots.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
This is the gist of it!
Couldn't hurt, but primarily we should pay attention to how we hit and what targets.
My 1st teacher was not into iron palm. For some reason he thought it contributed to arthritis. His classmate who also teaches said the same thing. Their fist both feel like a rock.
I like to hit the walls sometimes but do so sparingly. Who knows, maybe my teacher's right. My wife would tell me to cut it out and buy a heavy bag but we don't have the space for it.

Nah, i know people who have been doing it over 15 years and no arthritis. It all depends how you practice, if you're an idiot and go overboard then possibly. An iron palm stand takes up little space, or get a makiwara board or hanging canvas bag with the compartments, it's fairly reasonable and is better than nothing right? Plus it has give unlike the wall.
If you're a handyman you can make one from an old tire and a piece of plywood.

No problem! Hopefully it helps.
Most horizontal punches (chongquan) in the Shaolin boxing sets are not actually punches in application, but tend to be various throws. Punching comes from the vertical side palm structure (tuizhang)- vertical fist, elbow down.
Punching with the lower three knuckles is done in the vertical, elbow down punch where the the lower three knuckles are extended forward bringing them in line with the forearm bones, giving them support. Although the punch is straight, extending the lower knuckles causes the fist to rise in angle, which directs reactionary force into the stance with the elbow near the hip. Reactionary force is sent through the elbow, hip, and heel as the angle of the forearm with the elbow down is reflected in the lower rear leg of the fighting stance, thus sending more power into the target or into the ground to solidify the stance.
The vertical, elbow down punch also allows for simultaneous attack and defense. You lose all of the above in a horizontal punch with the first two knuckles. With the elbow up, reactionary force is lost through the shoulder and the function of simultaneous attack and defense (with a single limb) is also lost.
I broke the bone behind my little finger knuckle before. Happened during multiple punches. Broke it badly, I must have miss hit several times.
During training however the most annoying I find is injuring the thumb. Where it is tucked under the fist it can get caught and pushed backwards. Especially when your partner is partial to using the elbows to block. When you push through and really try to hit him it catches on the guard.
So much so I have taken to often holding the thumb to the side, or even partially inside the fist (joint still outside but nail tucked in). Sounds weird I know but it has its advantages.
