Something's not right with that. It takes roughly 1500lbs shock force to break a healthy person's ribs, and I seriously doubt you could apply that much force throwing her if you specifically tried. Does she have a calcium deficiency, vitamin K deficiency, or a bone disorder?
Edit: wow, love that people are downvoting this. I guess that's what I get for suggesting some possible health factors that could explain this injury that probably should not have happened, instead of making a low-hanging fruit joke or a meaningless comment amounting to 'ooh, ah' like most of the comments that got upvoted. You go, Reddit.

It's not uncommon to break ribs during CPR and they aren't putting out 1500lb

my 7 y/o niece broke her wrist falling on to the kitchen floor. runnin in the house with socks on, no grippies on the bottom. the human body isn't known for it's... durability. lol

you shouldnt be afraid of breaking ribs.. Most people who try cardiac massage don't apply enough force

I'd rather have broken alive ribs than unbroken dead ones.

this is so untrue. what dangerous information to spread.

Had CPR training recently as a high school graduation requirement and the instructor did say that not breaking ribs probably means you're not using enough force to get blood flowing through the body, although this varies from person to person. 2 inches is how far you have to press down (hence why ribs may be broken)

I didn't say you should intend to break ribs, maybe my wording could be better and I'll correct it, but most people are too afraid and don't apply nearly enough force
"about 30% of patients will find themselves with a broken sternum or a fractured rib. In some cases, multiple ribs will be broken but once again this should be considered absolutely normal"

You'd be surprised how much shock force you can put down with both arms locked, both hands focused into as small an area as possible, your full body thrusting on top, adrenaline flowing, and a person under you who is already injured or has chronic health issues.
If you break a rib though, generally speaking either they already had broken ribs or you weren't doing the correct compression technique for CPR. (Edit: or chronic health issue thing ofc)

I was actually a little worried about something like an occult cancer (fortunately nothing obvious on imaging). From a force perspective it's not actually that difficult from a pounds/square inch perspective. She weighs ~180 lbs and I threw her ~4 feet or so onto the bed with the vast majority of that force being transmitted through the heel of my palms. I'm also a relatively strong guy (can bench ~300lbs or plus force generated through my legs for the extra oomph).

Oh, you threw her in feet? Okay, I was thinking you walked up to the bed and tossed her down, not that you chucked her clean across the room.
I'm still a bit surprised that broke ribs though - I mean, even a full-force punch specifically intended to cause injury isn't usually going to do that, typically takes a clean and strong kick at least - so I'm still wondering about a calcium or vitamin K deficiency. Consider getting vitamin tabs of those.

I’m guessing the force was applied at an upward angle on the ribs, and not directly forward like a ouch would. The ribs would not be built for that application

My daughter broke my ribs while I was pregnant with her. She kicked and pushed incredibly hard for a fetus.

A woman's rib cage expands during pregnancy, and often but not necessarily returns at least partly to its original ahape later. I am not an obstetrician, but I would assume the ribs are weakened to accommodate that process.

That's highly doubtful, unless you were experiencing some sort of bone loss during pregnancy, fortunately I am a retired Nurse, so I understand how my body works. The entirety of a woman's body is stretched to it's limits during pregnancy, yes, but it's all within soft tissues that expansion happens. I am just certain that I had a devil child, who attempted to escape her fleshy prison many times. Haha

1500 lbs / 24 broken ribs = 62.5 lbs/broken rib
125 lbs wife / 62.5 lbs/broken rib = 2.0 wife ribs broken
edit: 180 lbs wife / 62.5 lbs/broken rib = 2.88 wife ribs broken (round down for actual fracture count)

You caught a slight typo - I meant 1500lbs shock force to break a rib. Obviously the size of the object is an issue but iirc that assumption uses something about the size/radius of a car's headlight corner area which is similar to a human hand.
Also your math is assuming sustained force, not shock force. By your numbers she would break ribs leaning over a chair.
