[|Human|] i have a 9 year old boy and he was hit by his surfboard and it indented his upper shin and left a large indent mark for the first hour that was indented at about 1/4 inch at least, after some time the large indentation that was the size of a golf ball started to dissapear up to 65%, is this common for kids to get a larg indentation in the shin?...I was quite shocked at first because i though his bone was actually broken!
[|AI|]  Dear parent, this indentation is caused by the force of the hit and yes it is possible to happen without any physical illness. But to make sure that it is normal you should exclude the presence of edema. You should press your finger against the bony part at the lower end of his leg for 5 seconds. Remove your finger. If there was an indentation mark then you boy is suffering from edema. If there was no indentation then no need to worry.
