Does kicking the stable door cause splints? Or make them worse?

[Flicker]

As per the question really. There is a cob on our yard who kicks seven bales out of his door on a regular basis, and for prolonged periods of time. I've posted about him before.
In the last 6 weeks he has developed splints - one h-u-u-ge one on his near fore and one smaller on his off fore. I'm just wondering if it could have anything to do with the door kicking.
I have suggested it to the owners but they just thought I was joking... oh dear.
About 6 months ago I did suggest putting up matting or something on the door, but of course this was ignored.
Now it is worth noting that I've known this horse for about 5 years and he has always kicked the door and, up until these splints has never had a day's lameness in his life. But I can't help feeling that there is a connection.
He has a very easy life - a bit of hacking and light schooling. And he is pretty overweight.
Has anyone got any ideas?

I wouldn't think the door kicking would cause a split, the impact is on the knee and fetlcok joint and in the opposite direction to the forces that cause a split. Splints can be brought on from one incident, he could have twisted badly in the field and casued it (the fact he's chubby wouldn't help) BUT I would try to convince the owners that the door kicking will not be helping hte splint mend. It doesn't cost much to put up some matting and foam! And it would do everyones ears a favour

An off cut of carpet nailed to the door can work well too
