A cast saw on human skin

One thing I forgot to mention is that the blade can get quite hot from friction. Another reason not to try this at home! The sponsor is Henson Shaving: Get 100 free blades here: hensonshaving.com/stevemould when you buy a Henson razor with code stevemould

“Shit wrong saw”

My first job was with prosthetic limbs, we made a lot of casts, most people almost had a heart attack when I pulled out that baby, was really hard to convince them it was safe. Neve knew exactly why it was safe, thank you Steve for that!

As an 11 year old in 1987 I vividly remember the doctor holding the case saw against his own arm to show me how it wouldn’t hurt me. Several casts and metal screws and plates from that broken arm I came to trust the cast saw and my doctor. Side note, I saw that same doctor more than 30 years after my broken arm and upon introducing myself as soon as he heard my name he immediately grabbed my left arm to inspect his work. He 110% remember me all those years later. Thank you Dr. Golden.

I am an orthopedic surgeon and cast saw injuries are quite common, even when an experienced person is using them. At my hospital there have been severe injuries. If you press the oscillating cast saw against a person's skin and then slide it, you will slice right through the skin. The blade can also get extremely hot if it is dull and can cause severe burns.

I only had a cast once when I was like 8 or so years old, and I was terrified at the saw being used once it was healed, and thought for the longest time that the doctors were just THAT precise and skilled with the saw xD

Wow I’m never using a cast saw to shave again! Those differences were insane lol

I’m loving all the comments of people sharing happy stories with doctors demonstrating the saw on themselves before using it on them. I never had a cast before, but as someone who is often terrified of medical equipment, that kind of understanding and demonstration is way more helpful than the doctor just apathetically saying ‘don’t worry’ and going for it when it’s clear the patient is confused and concerned.

Honestly, this is the first time I didn't completely dislike a "sponsor section" of a video. The information was - as always well presented, concise and relevant. Thank you so much for making those videos!

I have to say, I really appreciate that you took the time to explain why trying this for yourself is dangerous and how it could get you hurt, rather than just giving a boilerplate "Don't try this at home".

I remember being terrified of having my cast being cut off and the doctor just ran it across his arm while it was on and I was like “…oh” and I was fine. Honestly props to that doctor he must have had so many terrified kids coming in

Man that first freeze frame is priceless. Also the half beard. I can say that this is the most hillarious video you've made that I've seen.

I've actually always been wondering about this, but not enough to look it up, thanks for showing this.

This made me remember when I had my cast removed from my leg when I was a kid and was terrified of the saw and the nurse taking the cast off took the saw and pushed it right up against her own arm to show me that there was no risk of harm. It's something that immediately put me at ease and I let her continue without even so much as a flinch. I hadn't thought of that until this video. Thank you for reminding me of what looking back is a really fold memory.

About 60 years ago I had a little mishap resulting in a lower arm cast. When I went in to have it removed the doctor came in, and without saying much, turned on what looked like a rotary saw with the blade spinning and pushed it toward the cast on my arm. Before he contacted the cast I had his wrist fully clamped in my good hand, thinking this maniac was going to slice my arm with his crazy saw. The doctor's reactions were astonishment, then anger, then he laughed and put the saw on his own arm to demonstrate how it worked. So we both got educated; I learned about oscillating saws and he learned that patients may need to understand what he is about to do to them.

This is some great content and in content marketing. I really liked the scientific approach with east to follow formulas from strength of materials, and the merger with of the topic with the sponsor of the video was flawless. I did not skip through and might consider giving a chance to the shaver.

talking about those moduli and Poisson's Ratio really blew my mind. First time I've caught them out in the wild and not at work or school haha

the doctor explained this to me when he cut the cast off, but I'm glad to see someone such as yourself explaining this for the people that don't know, and you did it in great detail as well.

Hi Steve, minor correction from a UK Emergency Medicine Doctor. We still use plaster of paris as opposed to synthetic casts when you first break a bone. Plaster is better for the initial molding around the break. We also apply plaster to only one side of the cast, this is called a backslab. The soft side then allows for any swelling that occurs. This is usually then changed to a hard synthetic cast a few days later.

Very simple stuff and knowledge i had prior, but your videos are so worth a watch and the high speed cameras make things amazing.
