When I was a kid the doctor said I shouldn't worry because the saw doesn't cut trough skin... I still have the scar from the burning it did on my arm though.

How you use an 18v open standard power tool battery that works on multiple brands to try to make your razor point ^^

@@astropgn Me too. My scars are 30yrs old and my cast was made of the catalyzed fiberglas instead of plaster of paris. at least it also cauterized the wound it made but it also pushed the fiberglas dust into it. was crazy itchy for longer than I had to wear the post cast removal wrist brace.

My second wonder was, why use a circular blade when only a fraction of it sawing

@@GardenGuy1943 cast saws cant hurt you

@@guymanhumanperson they can cause cuts sometimes. but its very rare

I also had a cast (two actually, both ankles as my Achilles tendons were not growing fast enough), when it came time to cut the nurse asked me if I was afraid, and when I reluctantly nodded my head she held the thing to her arm and let me watch how it just tickled.

​@@MrRandoOnly if the doctor moves the saw too fast. Human skin is pretty elastic, but if one moves the saw too fast, the greater pull of the saw teeth overcomes the elasticity of the skin.

Idk why you people really need internet approval so much to make up these stories 😂

@@AlexandreG​​⁠I had a shit this morning. Do you believe me?

@@laurenanderson7330 of course, I was inside your whole peaking by the little whole I made. If you don't mind, next time pull down your pants more sensually, please

i was wondering about that; sliding it down the cast while cutting it and if it was in contact with the skin. thanks for your insight :)

Thank you for your comment. I had injuries on my leg twice from having casts removed. It was like a burn from my thigh to my ankle and it hurt like hell while they were doing it, but the technicians scoffed at me and said it was all in my head. Now I know what it was - they were burning me with the saw because it wasn't sharp enough.

Thank you! I had a cast removed on my arm as a child and the doctor‘s assistant absolutely burned my arm.

I got my cast cut off by an old cajun ortho when I was a kid. The dude told me 'if it cuts you, you can punch me'. Well I jumped when the blade went through the cast and it cut me. I didn't punch him though, he was a nice dude.

I don’t mean to sound too flippant, but it seems like you’re just describing Malpractice. They are operating the saw in a way it wasn’t intended to and causing harm because of it.

Same, I can't believe I've been making this mistake my whole life

Don't be so dramatic, just sharpen the blade.

Bah! Barely noticeable!

I couldn't see any difference. Gonna stick with my reciprocating saw.

seek therapy@@RepentandbelieveinJesusChrist5

Neat!

...Why do they have people operating those things without telling them how they operate lol. It's not that complicated... tl;dr "It just twists back and forth and the actual disc isn't that sharp, so all it does is scrape plaster and soft stuff like skin isn't going to get cut." This would also hopefully prevent the issue in another comment where some medical practitioner was running the thing back and forth along the cast so fast, that it actually caused skin scrapes ._.

Surely it would be really easy to convince them that it's safe: just put it on your own arm.

@@karlhendrikse That's what was shown to me as a kid. 100% fear shifted into 'what the everloving fuck how does that work I MUST know'

​@violetscott2322 thats what they did to me, too! It actually made me want to become a doctor!

Don't read the other comments then. It's not supposed to cut you, but it absolutely can.

99% of times it because the saw is in bad shape and didnt got any good treatment @@user-te2zq6tb9k

My thoughts exactly

xD

I mean almost anytime I've heard someone say to not try something they've explained it. Not like you can't do both lol

Yeah but don't they make those oscillating tools for cutting tile? Pretty sure he said Dremels were out, but as long as the tool oscillates you're good.

@@SpaghettiEnterprisesNo. An oscillating tool can oscillate too far and still cut skin.

​@@SpaghettiEnterprises"as long as the tool oscillates you're good" Not what he said at all!!!

You were lucky. As a 6 or 7 year old who broke my leg, the person who took the cast off seemed to enjoy my state of near panic as he held up the saw and started to go to town. Maybe I got a sucker out of the deal!

I saw a nurse do that the first time I saw a saw (🥴) and I think it's probably something that happens literally every time the saw comes out of the cupboard.

Same. I was 5 yo. Helping my dad trim a tree by carrying the branches away. Tripped and broke my arm by falling from my own height. Doctors discovered I had brittle bones then. When I took off the cast, nurse saw my eyes widen. I didn't say a word and she said whyle pressing the saw to her hand "Don't worry. It doesn't hurt. See?". I broke that same arm again the day I took off the cast riding a bike LOL. Wasn't scared of the saw the second time.

​@@ThZuaoDamn, that is insanely unfortunate. Can't help but giggle a bit.

@@ThZuao I was afraid that story might continue along the lines "...the same day we continued trimming the tree and I demonstrated to my dad what the nurse had done by pressing the chainsaw to my hand saying, 'don't worry, it doesn't hurt'..."

I remember my doctor attempting this and then he demonstarted on my arm and managed to break skin somehow

​@@HighCoupDeTatYour skin just had a terrible case of skill issue

Well in my country people are poor and we are like 20 years behind in termsn of technology so we don't have saws like that. And I've had a broken foot and what they do is they use a regular saw (I assume), because they insert a metal shin under the cast where they will cut and so if they break through the cast they will scrape the metal shin under it. The shin is thin however and I still feel like if it's somebody that is inskilled and moves slightly to the side outside of the metal shin area it can still cut into your body part :D

@@warrior1477 what country

​@@HighCoupDeTatdo you ever use body lotion? If you don't that might be why

Incredible story. While I would hope this would be less common today than 60 years ago, it's funny to think that doctors would go straight into some sort of procedure (since they're the trained expert) without explanation, which would look like attempted disfigurement to most people. I had my first cast at 11 and was very inquisitive, asked about every step and just really wanted to know what was going on (really more from curiosity than a focus on my wellbeing). First time a cast was taken off, I don't remember being scared of the saw, but thinking "Either this is going to hurt, they're very skilled with a spinning saw, or there's something I don't know". I just asked how it worked and if it would hurt because I wanted to know, but if I didn't have that experience until I was an adult, I would absolutely have gotten defensive before the saw could take my limb.

@@Faustvonholle My experience of most doctors today is consistent with the story, we the patients don't need to know anything, they will do onto us as they think is best.

@@Dreadought I hear what you're sayin you think it is, but how bout some antibiotics instead?

I had several fractures as a child and the man in the hospital who cut the casts of was super friendly. It looked like a really fun place to work and they were all jolly in that department. He always demonstrated the tool on his own arm to reassure the terrified children.

@@freshrot420 How about a cool opioid addiction?

That's very interesting, thanks for explaining! I only had cast as a kid (so... definitely more than 15 years ago since the last one now), and it was always only plaster of Paris, so I wondered about the modern stuff :)

Hi, David. Thank you for your comment. Could I also humbly ask you: what is the purpose of the change from plaster to plastic if in few days plaster is already fully solidified?

@@NikolayBychkovRus I presume they have to redo the cast because swelling has gone down and it would be loose, and since there's no chance of it swelling up again you can use the faster cast (that sounds like a great trade name)

Interesting, can I ask why? Is the synthetic cast less secure?

This is just a guess, but I would think the synthetic would be better in handling getting wet. I am not saying you would run water over it or soak it, but it could potentially handle getting wet (splashed not soaked) better than a plaster cast. Again, this is just a guess. I have never had a cast, so I have no personal experience with either.

Your doctor knows a lot of physics

I had a cast once and the doctor didn't explain it to me at all. Part of me was terrified that I would have my whole arm sawed off.

lol, well he didn't explain it in detail, but he did demonstrate that the blade won't cut skin. @@JustDinosaurBones

Haven't had a cast yet, but in the field of automotive repair we use something similar, which also oscillates to cut out body panels for less heat buildup to avoid it from warping. However, it might actually get through skin at some point since it isn't designed for casts 😅

oh, you poor thing. The trauma@@olivercharles2930

So what you're saying is I should use a oscillating multitool to cut off my cast?

​@@oliverer3you could very well

@@oliverer3 please dont

That is probably not a good idea. If the general principle us the same, the spécifications may differ, as explained in the video.

Fuck. Yeah. Do it!

Regardless of brand, for pure clean face shaving safety razors are just better; the only reason to use a plastic razor is if you didn't know any better yet. If you were doing some more shaping and grooming of the facial hair, you'd have more room for electric razors.

Clearly the smooth shave off the cast saw is much preferable, and way better looking too!

I'm not sure if I was clear, English is not my native language. I was talking about a razor in the style of the old razors used by barbers, except with razor blades, so you don't have to deal with the sharpening.

@@jankoodziej877 I believe those are called straight razors, and yeah if you know how to use em they're deadly effective cause they cut real clean and the typically load half a blade so you can just keep the other half clean and wrapped up for the next time you need it

@@sohamsengupta6470 yes, exactly what I was talking about.

You're lucky, my doctor just said "I haven't cut anyone.... yet" Child me was terrified

ohhhh bro @@Exsonius

Yep if they felt it and believe it they know they can press it on there skin and show you look it’s moving back and forth so little your skin moves with it. So it will only cut hard things on the surface.

Modern tools today I believe no matter the brand this tool won’t cut you and is it did you would have to really force it plus it wouldn’t even be mm deep it can hardly break the skin if you try and I’ve used many different brands from other people on the job. I do admit the best ones can hurt you a little faster but still really cannot hurt you. You won’t bleed at all for a minute then when you do it’s nothing and definitely less than you could ever do shaving.

Just breaks the skin slightly and is not dangerous. The attachment they use make it look rotary tho. It’s just for blade life and angles they can use still in it. They get better stuff than we do lol. But we can but similar also we can buy softer and give them a new edge with our drill attachment over and over until they become too short. You wouldn’t want these shavings in a human being I’m sure lol. But it’s same deal can’t break the skin and by the time it does you won’t know for minutes. Like when I guy is too rough with the clippers and later you get a couple little scratches. It’s about the same hard to really hurt anyone just good for hard objects. Maybe a shin bone but they gonna get away or kick you unless there tied well lol.

But wait there's more!

Guess I know what I’m getting the wife for Christmas!

Fun Fact: If you have really dry skin, your skin loses some of that elastic pliability and become susceptible to being cut again. I remember learning this from another UKposts comment section where a medical professional was sharing their experience doing demonstrations with the cast saw for kids, as a way to help them relax beforehand. However one day when they were preforming this demonstration on their hand like they normally would, their hand was somewhat more dry than normal, and they managed to actually cut themselves, much to the horror of the child they were attempting to calm down haha

An angle grinder works really well too except you often end up needing stitches :)

Man, you are awesome! I just bought a Makita oscillator multitool for my father in law, but looks like mother in law also will like it! ;)

Cheers for that.

I got hit in the eye with welding slag despite wearing safety goggles, and after that I always kept my welding mask down while chipping slag off.

Sounds like something right out of Saw 😂

Oh god no

Agh reading this is making my eye twitch yuck

how do you even get to a point where a full body cast is needed mate

@1v966 Open heart surgery was what I was in for, though my wording there was a bit off- Was just a cast around my torso, not "full body". My apologies. Lol

why can't the doctor just show it on themselves

@throwawaypt2throwawaypt2-xp8nx If I had to guess, to dispell any thought that he was somehow putting it close to him, without actually making skin contact. Otherwise, probably for comedic effect.

"Don't worry, kid, I'm going to scare the crap out of your mom instead!" -the doctor, probably.

So, instead of a spherical cow, it's a planar teat? Heh.

*Isotropic. Isotopic would be "about isotopes".

Also, it should be considered that skin (like many other biological tissues) is under tension on the body and this influences the wave propagation speed

As a fellow engineer, spoiler alert: they're all just (very good) approximations, some are just messier than others.

​@@SeanTerisuthis sounds like a pessimistic version of George Box's quote "all models are wrong, but some are useful"

I heard that, but I thought he meant it vibrated sideways. It was cool to see the slow-mo definitively explain what was going on.

When I got a cast off as a kid the guy just told me it was a magic saw that liked people and would never cut anyone. I believed this, somehow.

@@mahoganywolf8843 haha cute

my doctor used the saw on herself to show me it doesn't hurt

I was so afraid when my cast was removed. The assistant did say the saw does not cut my skin but I did not trust her as a kid. That thing looked dangerously like a mini circular saw. Showing me on her skin would probably have helped.

Booooo just kidding, that was pretty funny

It's waiting for the plaster of Paris shaving "cream" to set that is the onerous bit...

Absolutely, I got cut several times when they removed my cast when I was young. It was very hot as well.

@@bid0u12345 probably it was wrong one or faulty

I have a 35 year old scar on my wrist from a cast saw. Many things can cut you if used incorrectly or not maintained.

Aye I have a scar as well. It wasn't a problem, I just had a stuck partial cast that needed a lot of work to remove.

God I hate when the het hurts me

Well, fear no more! You can now enjoy the full experience in breaking a leg or two, getting a cast, have your friends and family leaving their signatures and drawings on it until the big final moment of removing it and you have a leg as good as new! Jk lol. It's such a liberating feeling when we discover these things that we've been afraid of and realize they weren't as scary as we thought. I'm happy for you, man. 🥳

yeah idk, I'm currently looking at the half-inch scar on my wrist from being injured via cast saw almost 10 years ago. I was in middle school, I vividly remember screaming at the sharp pain and the doctor looking at me like I was crazy. Beginning to wonder if they even had the right tool lmfao

@@noneofyourbusiness4133never had a broken bone, haven’t been to doctors in years. No talk or search relating even closely to this video.

I understood nothing of this, but I appreciate the information nonetheless.

Two very interesting points. Thank you.

Oscillations are always powered by something. Oscillations through the air are powered by your lungs when you speak. How fast those oscillations travel is the speed of sound through air. And by far field *region you're referring to the electromagnetic field around an object which would be relevant if we were talking about radio waves not sound waves. The speed of radio waves is entirely different from speed of the oscillation of compressive pressure (sound). Hope this clarifies things for you.

@@waxywabbit1247 this is wrong, and i dont think you understand. imagine this, you detonate a high explosive. the initial blast wave propagates at the speed of that explosive which is far higher than the speed of sound in air. once this hits air it will still go at that speed for some distance. this is called the near field, as you said this is also true for electromagnetic waves and is true of all waves. only after some distance will the blasts wave slow down to the speed of sound and propagate 'normally'. with powered i meant that the oscillations are forced at that frequency and do not yet go at the speed of sound for that medium.

I'm hoping that the casts are not a side effect of the job. ;-)

I would also suspect that the fact skin is firmly attached to whatever is under it has a huge effect on the waves generated too.

Poor adults might've had unexplained traumas

Adults are _always_ worse than children. Children are capable of following simple directions and are easily appeased and distracted. Adults don't think they _should_ follow directions, and can often be so allergic to information that you can't even get directions across, much less get them the hell out of the way of danger. Children don't have overinflated egos and a sense of entitlement, they're the kind of dumb that's easy to manage.

If I were the doctor I'd put a big show and say: "Watch out, kid, this will cut off your arm if you ever so twitch even a hundredth of an inch!" And then approach the cast veeeery slowly. (" oДo)

@@fsmoura thank f**k you're not a doctor

... Apparently they didn't always use oscillating saws, or I had tighter skin. Still have scars. They're most visible if I get a tan.

@@hariman7727 the thing they forgot to mention is that as these blades lose their edge they generate more friction and get hot enough to burn through your skin... i've got scars as well and they've been there for the last 30 years

They can actually do both

I had almost exactly the same thing. Drs had to cut open a full leg cast because my leg was still swelling more. Didn't Believe me until the cast popped open and they saw blood all the way along. Still visible scar over 20years later.

That would probably be an incompetent doctor. Cast saws absolutely can (and do) cause minor burns and cuts when properly used, but a serious burn or something indicates operator error, most likely from dragging hte saw along the skin. The proper way to cut a cast is by a series of cuts into teh case from the outside moving down it as you go (think like an old style can opener: make one cut, move a bit, cut again, move a bit, cut again, etc, etc) not a cut along the. This both gives the blade constant breaks and keeps it from being in contact with your skin for extended periods.

That might have been what happened to the person I mentioned in my previous comment,@@88porpoise .Well noted.

This exact thing happened to me as well. I think I was 8, they assured me it couldn't possibly be cutting me even though I could feel it hurt and told them. I let them keep going, I had a pretty high pain tolerance for a kid (I had lived with the broken arm without treatment for a week before telling my parents I had hurt it - oops). Then when they cracked it off I had a 2inch burn and they felt pretty horrible. I still have that scar.

Found Ron Swanson

I'm one of them, looking at the scar currently on the hand that's holding this phone. Just a little contact patch of the blade though at the base of my thumb.

Yep I have a scar on my hand thanks to the idiot doctor that cut my cast off. Dude was so rough he sliced right into my thumb and wrist

I’m one of them too and still have the scar, she thought I was feeling “phantom pain” because I was scared of the saw :) nah, the saw was too old and cut my skin, I have the scar to prove it and I threw up from stress while it was happening

I should have sued the hospital for neglect. I got traumatized of hospitals for a while because they cut the cast AND the skin under it...

Probably because their skin was too dry to stretch

That's appalling! Scars both mental and physical I should think. My brother had to be catheterised regularly and he had one nurse who did it badly and he told her she was hurting him and she said "oh everyone says that" YEAH WELL THEN LISTEN TO THE PATIENT maybe?? Man I'm angry for you, I hope you put in an official complaint.

I had the same thing happen to me when I was 7ish, I still have the scar on my leg.

Yep cut me and left a scar from top to bottom of my leg that took years to clear.

I had the exact same experience! It was in second grade, and she cut my arm in 3 different places which ended up getting so badly infected my hand swelled up to the size of a balloon and had to be hospitalized a week later. At first they were convinced I must have been bitten by a spider or something and it wasn't until the second day in the hospital they they realized it was from the infected cuts.

yup same here, broken ankle cast being removed. I said ouch that hurt, lady assured me i was fine. Blood was running down my leg lol

Is that pun unintentional?😂😂

made me flinch

Scared the heck out of me

Made me shiver

The video cut or the arm cut?

There's another kind of oscillating tool that's very widespread. Oscillating saws have become extremely common in the power tool business. They're actually quite similar to that cast saw. You can go to any hardware store and find a wide variety of them from all the major brands. Very useful tools for detail work or cutting in confined spaces. Wouldn't use them for cutting off casts, but theoretically you could.

hahaha im gonna try that 🤣

@@ccoder4953 its most commonly called multitool because it has many kind of functions

It's also good at locating prostate cancer, if you weren't aware.

wut? :O how?

Sounds like a lot of people didn't understand this tool.. You're not the first one I've seen on here saying that.

Ouch. Were they just pushing too hard?

You are not alone. Broken wrist in the late 90s. Exact same scenario. Horrible pain, being told, I was wrong and it could not hurt me, only for cast to come off and my hand covered in blood. Scar is barely there some 25+ years later, but it for sure cut me somehow.

@@Digger813 It sounds like the cast was on so tight the skin couldn't deform. Being held tight the saw was able cut thru just like the blown up balloon. kinda like holding both sides of some plastic wrap tight so you can cut it.

What an amazing coincidence-I only just talked to someone who had the same experience. She also got nicked by a cast saw as a child on her left arm, but somehow she ended up getting both cut and burnt. It's definitely a rare phenomenon and she must have been really unfortunate, even compared to other people who get hurt by those saws. If I remember correctly her injuries came from the fact that the padding material under her cast was not evenly distributed and there was not enough of it in the area where she got her injuries.

Probably what happened to me. I've got a couple scars on my arm from a cast saw.

damn that took a very dark turn. was not expecting that. rip to him man damn
