Broken sternum hereditary?

I'm 19 years old. i was in a car accident as a penger. I broke 2 ribs on my left side. My L2 vertebrate. And my sternum. It's been 3 weeks since my back surgery, they put in 2 rods. Right now my sternum is still raised, i'm uming the bone is inflamed or something. but I feel it and it's noticeable to me. I was wondering...if I let it heal and it stays like that--- when i have kids someday, will they have raised sternums too? or something abnormal? ...It's good to be alive, i'm thankful everyday. just a thought that came across my mind.
