This past weekend while at work, one of the emergency department MDs with whom I have a pretty good rapport called me up in the ICU and told me to come down to take a look at something 'absolutely remarkable'. A young Latino man had arrived via ambulance after developing all the signs and symptoms charateristic of what is commonly referred to as 'acute abdomen'. Radiologic images were promptly taken and these not only confirmed one, but multiple points of small bowel perforation, as well as the presence of numerous metallic fragments scattered throughout the peritoneum -- the largest of these fragments having been lodged in the inferior-most aspect of the man's sternum. Strangely, however, the man denied having been shot and an entry wound could not be located anywhere on his torso. His only other injury was a large hematoma on the posterior aspect of his right leg, just above the knee. Finally, the MD on the case and the one who called me up in the ICU to come down and take a look, ordered CT scans of the man's entire right leg and foot. Sure enough, there was tissue damage all the way from his heel up through his right hip. The hematoma on the back of the affected leg was the result of a bullet having cut into the great saphenous vein. And a very small, ragged entry wound was located right on the center of the heel.

The HPD were notified and they promptly sent detectives to come and interview the man. As it turned out, he had been at a 'kegger' much earlier the same night where some idiot pulled out one of those silly, little 'starter' pistols -- the .22 Long Rifle jobbies -- and squeezed off a few. One of these struck our misfortunate patient in his right calcaneous bone, took an abrupt turn upward and somehow managed to eat it's way up through the length of his entire leg, through his a$$, and through all the periotoneal viscera, whereupon it finally came to rest on the backside of his lower sternum. And the man didn't even realize he'd been shot until we told him the massive peritonitis from which he was suffering was the result of the bullet having punctured his small bowel in mutiple places.

I'm still incredulous over this case!!! I mean, c'mon . . . a .22 LR from a pistol? It just doesn't generate any kind of real kinetic energy!!!
 
... So it was a .22 that got JFK? Jokes aside, wow that's some serious travel and the fact that it traveled all that way internally without breaking skin. Surprised his leg wasn't sore from where it cut the muscle unless the particles were so small it didn't effect motor function
 
Entire length of his leg? Wow .22lr = 3 feet penetration...imagine that..
 
add that one to the "bullets do strange things" file. Bullets don't pay attention to kinetic energy, velocity, etc.....sometimes these things are just hard to explain.
 
I call bull****.
A .22 won't go 3ft in water let alone muscle, there's no way. I'd love to believe it, but there's just no way.
 
.22, or .223?

I call BS if this is supposed to be just a .22LR.

I can see that it might be possible with a hot loaded .223.
 
It didnt' go through a bunch of cortical bone. And saying that it can't penetrate 3ft of H20 isn't all that telling. The bullet could ride in fascial planes going up the leg (i.e. epimysium), which would possibly present less resistance than even water. If you've ever dissected an unfixed human, you know how easily spread those tissues can be. So you can potentially almost write off most of the distance up the leg. Then all you've got it is a ricochet and then 12-14" of abdominal viscera to really rob bullet energy.

Put it all together and it's very amazing, but very possible.
 
Yeah, but bouncing off the concrete takes a LOT of energy. Plus, if the thing fragmented THAT much, how's it going to have the sectional density to travel that far? Sternum? Unless we're talking midget here, I have a hard time grokking the whole thing.
 
As people have said, bullets can do some very odd things. I don't doubt it happened, but I'd be surprised if you could get it to happen again. :D

Hopefully the wounded fellow was fixed up and released with a clean bill of health. That can't be fun at all.
 
:what: :what: :what: Bullets do indeed follow the laws of physics. trust me, i know. That's a bad Kimber1911, BAD!!! As far as the ballistics of this, I wrote a computer program one time to calculate the density of material required to stop a bullet in 1 mm with muzzle energy and mass of 7.62x39mm. I just used avg values from what I found on the net. It ended up being roughly 1000 times denser than water, which I think means that an Ak round will go roughly 1000mm in water. :D I could be wrong though, I'm not that smart. :banghead:
 
saw this one in person.... one bullet, unknown caliber, but i'd guess it was a pistol.... ricochet off floor, into leg, out of leg, clipped his penis, into his nose, out right below eye, then through eye into brain and bam, done deal.


he was alive technically last i saw him, but neuro said he was pretty well done. i honestly cant remember where he went after the ER, but i'll never forget the path of that bullet. straight up the body, shallow penetration/grazing wounds. except for the 2 small wounds in his lower leg, the small graze to his penis, the small bloody hole in his upper nostril, and the blood from the corner of his eye, he looked perfectly fine.

worst, most freakish AD/ND i've seen
 
.22 LR bullets are notorious for doing this sort of thing. The low FPS keeps the bullets intact even through lots of tissue, and their small size and lack of temporary cavity means they can slip deep inside, esp. traveling under the skin and slipping along the muscle and bone. There are many antecdotal descriptions of men getting shot without knowing it and suddenly dropping dead hours later. President Reagan was almost one of them.

22, or .223?

I call BS if this is supposed to be just a .22LR.

You have it the wrong way around. A .223 is going far, far too fast to stay intact for that long, or to take such dramatic turns. The wound characteristics for a .223 hit are completely different, with massive temporary cavities and limited penetration. .223's don't shift 90 degrees because of bone, and they don't travel up legs without the person realizing it!
 
Wow...I could see this happening, in a "struck by lightning" sort of way.

Bullet was traveling up the leg perpendicular to muscle tissue---going "with the grain" so to speak. Stilla amazing it made its way all the way to the sternum without hitting anything solid/semi-solid enough to stop it. Surely a 1 in a million deal.
 
I have heard of a similiar incident where a .22lr entered into a person's chest traveled down the leg and out near the heel.
 
Yeah, but the doc in this case said that it broke up/fragmented. If it hits the floor, I'd guess it'd fragment there, but then go back together and stay together on a magical path up the leg until hit hits the gut?

Figure you're starting at what, 1,000fps. 29 grains?

I wonder how much of that a ricochet ate... And did it have to penetrate a shoe to hit the heel?

Oh heck, I shoot a .45, loaded right now with 230 grain roundball. All I gotta do is graze a pinky.
 
Gentlemen,
We're assuming a whole lot of things at this point (e.g. the bullet ricocheted off something inanimate object before hitting the victim/patient in his right heel). In order for this kind of once-in-the-history-of-the-universe thing to happen, we still have to concede certain factors. For one, the bullet must have entered this man's body shortly after having exited the muzzle of the gun from which it was fired, and without having struck or passed through any other media before doing so. Also, the man would have had to be standing or lying in a way perfectly conducive to his body's tissues giving way to the projectile that 'ate' through him 2/3rds to 3/4ths of the way. Additionally, upon splashing into the victim's/patient's body, the projectile would almost immediately have had to deform into a shape perfectly conducive to its traveling the distance it obviously did travel.

In other words, a confluence of errors occurred in this instance that lent itself to allowing for the otherwise completely impossible. BTW, the only bullet fragments between the entry wound and farthest distance of travel were found above the patient's umbilicus. For some reason, the bullet did not start breaking up until it had passed well into his abdomen.

This is the second time in my nursing career that I've seen 'freak cases' involving GSWs. The first time occurred in the summer of 2000, when ER/ED staff brought a skinny teenager to me in the SICU after he'd been shot at point blank range with a Glock 22. The bullet struck this kid square in one of his thoracic vertebrae, made a 90-degree turn to the right, and came to rest in the lower lobe of his right lung. The vertebrae remained perfectly intact, however, except for two tiny chips of osseous tissue that showed up in the X-ray films. The kid otherwise suffered no spinal cord damage, no spinal shock, no paralysis . . . not even any parasthesia! The surgical resident assigned to the case simply dropped in a chest tube for the partial, right pneumothorax he suffered. And a week later the kid went home!
 
I've seen some good ones, but this has me beat.

I would take his kegger story with a grain of salt. If the bullet were fired at relatively close range and in a relatively straight line from the line of travel, it could have followed the surgical planes to the abdomen. .22s can do funny things.

I'll bet money he was laying down, maybe next to someone's girlfriend? :evil:
 
Dr. G Medical Examiner had an episode where a .22 revolver was dropped from an ironing board and went off (it was old). It entered the forehead, curved around the scalp and lodged behind the ear. Oddly the guy died, even though it never entered his brain.
