Chemist and Biochemist [Thunderf00t] has shown us a really interesting video in which you can spot the wrist he broke 10 years ago using a thermal camera.
He was on an exercise bike while filming himself on a high-resolution thermal camera, As his body started to heat up he noticed that one hand was not dumping as much heat as the other. In fact one was dumping very little heat. Being a man of science he knew there must be some explanation for this. He eventually came to the conclusion that during a nasty wrist breaking incident about 10 years ago it must have affected the blood-flow to that hand, Which would go on to produce these type of results on a thermal camera while exercising.
Using thermal camera’s to spot fractures in the extremities is nothing new as it has the benefit of eliminating radiation exposure for patients, But it’s not as detailed as an X-ray or as cool as fluoroscopy and is only useful for bones near the surface of the skin. It’s still great that you can visualize this for yourself and even after 10 years still notice a significant difference.
First of all, ouch! And cool hack.
Secondly, why do so many YouTube videos cut off the text on the left side?
It is a handy medical diagnostic tool, but be careful of other, differential, diagnoses. Is one arm cooler than it should be, or is the other one inflamed and hotter than it should be?

For someone who tires to be scientific his conclusion isnt very scientific. It could be that just how its allways been and its pure coincidence.
That is a logical point, e.g. if an MRI finds a mass it isn’t cancer until the surgeon has provided the pathologist with a sample. Although he has prior knowledge that is relevant other possibilities must be eliminated.
Thermal visualization of an extremity has very poor specificity for any fracture as any inflammation (such as cellulitis or a contusion) will cause an increase in temperature. Probably a more apt title would be something along the lines of using a thermal camera to look for dissimilarities in blood flow between two extremities while exercising. One can have a hairline fracture and not have any significant enough alteration in blood flow to show a difference with a thermal camera years down the line. In addition, a change in blood flow does not automatically signify a fracture as other things can cause it such as surgery, more metabolic demand in that extremity, clots, and mass effect.
agreed. I don’t think this is very scientific, no controls, no calibration. not saying it isn’t possible, just that this proves nothing.
You forgot to add misogynist after chemist
I watched several of his videos. I think you’re incorrect.
Do you really want to turn this from an interesting discussion of possibly detecting bone fractures using IR imaging to some kind of argument over how many females play video games?
Go back to commenting on YouTube.
I think he(?) is correct but this isn’t the forum for discussing that.
He’s an asshole, the people he complains about are assholes, everyone’s an asshole….
????Everyone’s an asshole????
????Everyone’s a a bitch when you think about it????
????Everyone’s an asshole????
????So just get over it????
(to the tune of everything is awesome)
Is this the best you can do with your life?
I would agree with both of you yes he is and this isnt the place.
Look here everyone it’s an”” ATTRIBUTE SETTER “” a rare kind of dog that smells with fiction then liberally applies fiction to everything it sees based on crazy therapists from the 1800s.
Did you just have a stroke? Hmm… perhaps a thermal camera could detect that!
I thought the same. Was going to ask him if he smelled toast!
I wouldn’t say ‘misogynist’ so much as a bit off the rails in general.
take it somewhere else ngart
It’s OK snowflake, trigger warning next time scouts honour.
Really mature.
How was my comment Immature? also noticed you are from Carlisle I’m just over the border in Dumfries ;)
‘Snowflake’ & ‘trigger warning’ are lazy ways to dismiss someone who points something out. TF *is* a creepy wanker, sadly.
(All IMO, obvs)
Passed through Dumfries just recently! Used to go to the market there years ago.
I get what you are saying however TF isn’t a misogynist he just isn’t PC. He is an egalitarian.
Market used to be good but town is dead these days. I can’t reply to your new comment unfortunately. Small world though.
Didn’t watch the video, so no comment on that guy.
I’m assuming you’re just unconcerned about the way you come across to people?
‘Snowflake’
Sarcastic comment about ‘Trigger warnings’
‘Isn’t X, just isn’t PC’.
A friend of mine calls this ‘alt-right bingo’. Out of curiosity for my own mental associations (you’re UK, right?), what are your opinions on Brexit, Farage, Trump and Corbyn?
HACKaday people. Let’s stop this now, please.
I agree with notarealemail lets leave politics out of this, I prob shouldn’t have called someone a snowflake however I am def not Alt-right or even right wing for that matter.
I’ve often noticed a mottled or splotchy pattern when hands feel inflamed or oddly hot.
The patterning is usually something like a 3~5mm spot sized, camouflage style repetition.
The other thing is it’s always more pronounced as you age.
Being as this is anecdotal (40-odd years)observation, I can’t say if it correlates to any particular lifestyle or work.
His vasculature in the post fracture extremity may be as good or better than the uninjured side; the more distal hands are equally warm, judging by the scan, suggesting uninterrupted blood flow to the extremity.
What may have been affected by the fracture is the sympathetic innervation controlling the blood flow in the skin – https://www.ncbi.nlm.nih.gov/pubmed/2212486
Very good post. I am experiencing some of these issues as well..
I liked your comment on how using thermal cameras can get rid of radiation exposure. My brother broke his arm recently, so thanks for the tip on being able to see it better with thermal cameras. This seems like a helpful way to use these types of electronics. http://www.infraredcamerasinc.com/
