You’d think it’s a death sentence. Honestly, most people hear "nail in the head" and imagine an immediate, grisly end. It’s the stuff of cartoonish accidents or horror movie tropes. But the medical reality is actually way more complicated and, frankly, weirder than that.
Brains are fragile. We know this. Yet, the history of emergency medicine is littered with cases where people walked into ERs perfectly conscious while literally carrying a three-inch piece of galvanized steel in their skull. It happens more than you'd think. Construction accidents, DIY projects gone wrong, or even intentional acts of violence—the human body has this terrifying and beautiful ability to sometimes just... keep going.
The Physics of Why a Nail in the Head Doesn't Always Kill You
It sounds impossible. It isn't.
Whether someone survives a nail in the head mostly comes down to two things: location and velocity. If a nail hits the brainstem or a major artery like the internal carotid, it's game over. That’s just basic anatomy. But the brain has "silent" zones, particularly in the frontal lobe. You can poke a hole there and, while it’s definitely not good for you, it might not flip the off-switch.
The Low-Velocity Advantage
Most of these injuries involve pneumatic nail guns. These tools are powerful, but they don't have the muzzle velocity of a firearm. A bullet creates a permanent cavity but also a massive temporary cavity—a shockwave that shreds surrounding tissue. A nail is different. It’s a slender, relatively slow-moving projectile. It displaces tissue rather than exploding it.
Think of it like a needle. If you push a needle through a piece of gelatin, the damage is confined to the track of the needle. The surrounding gelatin stays intact. The brain has a similar, though much more complex, consistency.

Why Surgeons Don't Just Pull It Out
You might see someone with a nail in the head and think the first step is to yank it out. That is the absolute worst thing you could do.
Surgeons at Level 1 trauma centers, like those at Massachusetts General Hospital, treat these objects as a plug. The nail itself is often what's stopping the person from bleeding out. It’s tamponading the wound. If you pull it out in the field, you release the pressure, and the patient can hemorrhage in seconds.
Famous Cases That Baffled Doctors
We have to talk about the "accidental" survivors. Take the case of Dante Autullo in 2012. He was building a shed, the nail gun recoiled, and he thought he just had a scratch. He went about his day. He even posted a picture of his "bruise" on Facebook.
It wasn't until the next day, when he felt nauseous and a bit hazy, that he went to the hospital. An X-ray showed a 3.5-inch nail buried deep in his brain. He had been walking, talking, and eating with a nail in the head for nearly 24 hours. He survived.
Then there’s the 2006 case of a man in South Korea who went to the hospital with a severe headache. Doctors found a two-inch nail that had been there for years. He had no memory of how it got there. The brain had essentially scarred over it. It sounds like a tabloid headline, but these cases are documented in medical journals like the Journal of Neurosurgery.

The Role of Modern Neuroimaging
When a patient arrives at the ER, the protocol is rigid.
- Stabilization: Keep the head still. Any movement of the nail could sever a new vessel.
- CT Scan: This is the gold standard. Doctors need to see exactly which structures are impaled.
- Angiography: They need to know if the nail is touching an artery. If it is, they might need to perform an endovascular procedure to block potential bleeding before the nail is even touched.
The Surgical Approach
Removing a nail in the head is a delicate dance. It often involves a craniectomy—removing a piece of the skull—so the surgeon can see the point of entry and the surrounding vasculature. They use specialized tools to gently back the nail out while simultaneously being ready to cauterize any vessel that starts to spray. It’s high-stakes, high-stress work.
Long-Term Consequences and Recovery
Survival is one thing. Living a normal life is another.
Even if the surgery is a success, the risk of infection is massive. Nails aren't sterile. They’re covered in oil, dust, and bacteria. Introducing that directly into the subarachnoid space is an invitation for meningitis or a brain abscess. Patients are usually pumped with heavy-duty antibiotics for weeks.
Epilepsy and Personality Changes
Traumatic Brain Injury (TBI) is almost a guarantee. The scar tissue left behind can become a "focus" for seizures. Post-traumatic epilepsy is a common long-term side effect of a nail in the head.

Depending on the lobe affected, you might also see:
- Executive function issues (difficulty planning or organizing).
- Sudden impulsivity or aggression.
- Loss of fine motor skills on the opposite side of the body.
It’s a long road. Physical therapy, occupational therapy, and often psychological support are non-negotiable parts of the recovery process.
Essential Safety and Immediate Action Steps
If you are ever in a situation where someone has a nail in the head, your actions in the first ten minutes dictate whether they live or die.
- Do Not Touch the Nail: I cannot stress this enough. Leave it exactly where it is.
- Stabilize the Head: Use rolled-up clothing or towels to keep the person’s head from moving.
- Keep Them Calm: An elevated heart rate increases intracranial pressure and the risk of bleeding.
- Call 911 Immediately: This is not a "drive yourself to the clinic" situation. They need a trauma team.
In the world of construction, the move toward "sequential trip" triggers on nail guns has saved countless lives. "Contact trip" triggers—the ones that fire whenever the nose is bumped—are responsible for the vast majority of these accidental injuries. If you’re a hobbyist or a pro, check your tools. Switching a trigger is a five-minute job that prevents a lifetime of neurological rehab.
The human brain is remarkably resilient, but it isn't invincible. While surviving a nail in the head makes for an incredible story, the medical reality involves grueling surgeries, a high risk of permanent disability, and a lot of luck. Stay safe, use your tool guards, and never underestimate the damage a small piece of metal can do when it finds the wrong path.
