What Is the Most Easily Breakable Bone? The Answer Hurts

The quick answer: it’s the clavicle (a.k.a. collarbone)

If you’ve ever taken a hard fall and landed weird on your shoulder — you probably already know. The clavicle, or collarbone, is one of the most commonly broken bones in the human body. It’s thin, it’s oddly placed, and honestly? It doesn’t take much to snap it.

I remember when my friend Jordan wiped out on his bike — not a crazy crash, just a stupid slide on wet pavement — and boom. Broken clavicle. He said he heard a crack before he even hit the ground. Brutal.

But wait, there’s more to this story than just "it's fragile." Let’s dig in.

Why is the collarbone so easy to break?

Its location makes it vulnerable

The clavicle is that S-shaped bone that sits right between your sternum (chest bone) and shoulder. It kinda just... hangs there. Not super well-protected, and not very thick either.

You fall forward, sideways, or catch yourself awkwardly with your arm — that poor little bone ends up absorbing the impact. And it’s not just athletes. Kids, seniors, even clumsy people like me (yep, guilty) are at risk.

It connects a lot but isn’t reinforced

This bone helps connect your arm to your torso. It’s important for shoulder movement, posture, balance — yet it doesn’t have a ton of muscle or padding around it. So yeah, it’s doing a lot of work... with not a lot of backup.

Other bones that break easily too (because yes, there’s competition)

The wrist (distal radius)

If the clavicle has a rival, it’s the wrist, especially the distal radius (the big bone on the thumb side of your wrist). This one’s a classic — fall with your hands out? Congrats, might be your wrist.

Happened to my aunt slipping on ice. She didn’t even fully fall — just caught herself weird, and pop. Six weeks in a cast.

The ankle (especially the fibula)

All it takes is a wrong step off the curb or a twist in a soccer match. Your fibula, the smaller bone in your lower leg, is not that sturdy. Combine that with body weight, awkward angle, and boom — you’re hobbling for weeks.

The ribs

Okay, technically harder to break than the clavicle, but they do crack easily under pressure. A bad cough, a hit in contact sports, or even just a twist the wrong way — and suddenly breathing feels like punishment.

Who’s most at risk for bone fractures?

Kids: because they fall (a lot)

Kids are mini stunt people with no fear. They climb, run, crash, and bounce — except sometimes, they don’t bounce. Their bones are still growing and more flexible, which helps, but also... they fall constantly. So clavicle breaks? Super common.

Older adults: because bone density drops

Now let’s talk about the other end of the spectrum. After around age 50 (especially in women), bone density starts to decline. Osteoporosis kicks in. Suddenly, something as simple as tripping on the stairs can lead to a fractured hip, wrist, or yep — clavicle.

Athletes: because... life

Contact sports, skating, biking, snowboarding, gymnastics — all fun until someone takes a bad fall. I’ve met at least three people in the last year alone who broke their collarbone doing something “harmless” at the time. One was just running and slipped on wet grass. Unreal.

How do you know it’s broken?

• You’ll feel it. Trust me.

• Pain when you try to lift your arm

• Swelling or a bump where the break is

• Sometimes even a weird grinding feeling (ew)

• You might even hear the snap (double ew)

Jordan said lifting his arm felt “like trying to raise a wet towel full of broken glass.” Pretty vivid.

Final thoughts: fragile doesn’t mean weak

So, what is the most easily breakable bone?

It’s the clavicle — that skinny little bone holding up your shoulder like it’s doing too much with too little.

But hey, breaking a bone isn’t a sign of weakness. It happens. Sometimes it’s a moment of bad luck. Sometimes it’s just physics doing its thing. What matters most is how you recover — physically and mentally.

And next time someone says “it's just a broken collarbone,” you’ll know — there’s nothing “just” about it. That thing hurts like hell.

Even with a healthy diet, most people's height won't increase after age 18 to 20. The graph below shows the rate of growth from birth to age 20. As you can see, the growth lines fall to zero between ages 18 and 20 ( 7 , 8 ). The reason why your height stops increasing is your bones, specifically your growth plates.
