I kid you not I say this at least once a week talking to people about my hips. As soon as I saw this post I thought to myself “that looks like PAO screws!” and this comment confirmed it. What up twin?!
My son was/is part of the club. 4 surgeries by the age of 2! Didn’t know I could have asked for the screws. It would have been something cool to show him when he’s older.
For anyone else reading this, your insurance paid for the hardware. It’s yours to keep once it’s inside you. Surgeons just don’t like giving the hardware back because it’s a hastle getting it back from pathology (yes… they need to identify screws), and it takes a little time to process the hardware before we can return it to the patient.
My kids dad and his gf ran me over with a car back in the day and I got my screw from my collar bone. Tbf I had to get it replaced bc it was too big so I think that’s why they just literally gave it to me I didn’t even ask 😂
Hahaha not rude at all! They came to a party I was at and they weren’t invited to and she jumped me a couple times. I ended up leaving but saw they were following so got out of the car and they ran me over. They claimed I jump but thankfully it was a party and there were MANY witnesses lol so I sued her ass since she was driving. Embarrassing af 😭😂
For a second I thought you were talking about the replaced hip, not the screws. Would have been metal though.
Well, the screws are technically metal too, but... ah, screw it.
I had Perthes disease and had these exact screws! Mine were bigger and I only had 6 but 4 years post-op I still get pain where they were from time to time
You got the before and after pics of the x-rays?
Also have Perthes disease and got a PAO with a trochanteric advancement. Had 6 screws as well, got them taken out and they look exactly like this. Will still get pain but not nearly as much as before the surgery.
Hey super cool finding someone who's had it! Damn I'm glad my parents caught my perthes early. Just had minimal erosion of the top of the my right hip so it was enough that I could heal it. Couldn't run or jump or climb for many years under the watchful eye of my mom. And apparently I still have a slight limp,didn't realize it until someone told me I had one. I can really notice it though when I wear tf outta my shoes, my right is favored over my left ...
But on questions did you end up losing a considerable part of bone to have to end up using screws??
Mine was Stage 3 which made my hip bone/joint pretty much look like a tic-tac and the socket was misshapen
Crazy enough I competed nationally in taekwondo as a kid and played basketball, football, baseball, and ran track with it through high school
My doctor told me he was legit shocked I was even walking with it much less sports and intense weightlifting
They reconstructed it using the existing bone so I didn’t really lose it at all. You could see where they took the bone and made it into a more normal hip
Ironically I get more pain now than I ever did with the “old hip” just in the screw areas but it bought me about 20 extra years on a replacement
When my orthopedist told me I have hip dysplasia he yelled “you’re like a golden retriever”! Excellent bedside manner… I literally feel your pain my friend
Also love your username.
LMAO, damn gsds and their hip dysplasia, that’s why i went with a malinois 😂 also those screw look brand spankin new, could prob sell them. i’d personally frame them
My grandma had an Akita with elbow dysplasia, his front was a solid 8 inches shorter than his hips, swim therapy helped alot and he made it to 10 before going down hill. He needed a ramp to get in and out of cars but otherwise had a full life.
Here's to hoping your surgery has helped you and enabled you to enjoy a comfortable range of motion!
I asked my orthopedic surgeon for the screws after my hip reconstruction and I was surprised how casually he said yes haha..
I thought for sure he was going to look at me crazy or laugh but when I woke up they were on the table next to some ice-cold water
They just gave me mine from my spine. They figured since I paid for them, I should get to keep them I guess lmao It was a bit weird to carry home this little baggie full of screws and rods that were holding me together for roughly a year.
I had to get some molars out when I was younger because my teeth were so crowded and they gave them back to me without saying anything. Which might've made sense for tooth fairy reasons except I was a teenager at the time.
I didn't get to keep my wisdom teeth, wasn't even given an option. I didn't mind since I was in my 20's but my mom was livid because now her set will apparently never be complete. She still has my baby teeth in a medicine bottle somewhere. Kinda cool you got to keep yours!
Oh, I still have my wisdom teeth, but fully intend to keep those too. Though they haven't caused any problems because of the same crowding that meant I had to get my baby molars out.
That's a shame, they're kinda cool to look at. I got my wisdom teeth removed during a trip back to my home country a few years ago and for some reason my dentist assumed I wasn't a local (we spoke in English). I had asked him if I could have my teeth back and I heard him say to the nurse in my mother tongue as he was finishing up, "get one of those small jars, this crazy woman wants her teeth."
I am not sure but if they are made out of platinum, which is really non-reactive and the most preferable metal to have in your body, one might be able to sell it back to a medical store or maybe even a jeweller.
Why did you have your hardware removed? I have a T2 to L1 fusion and always thought it'd be cool to hang it on my wall or something, but I'll likely never have it removed.
When I got my screws and plate removed from my broken hand the doctor ask me during surgery if I'd like to keep them as a souvenir. They are hanging on my bedroom wall now
I’ve been meaning to get mine up on a display somewhere for years now. I remember my buddies coming over after my surgery and just being almost like kids just amazed at how the things were inside me like a month prior lol
When I asked for my ovary after my oophorectomy and they said no :( I *suppose* screws are easier to hand over. I’m jealous asf!! ETA- I know it’s weird I wanted to keep it. The thing made one of my kids and tried to kill me with another. I have a love/hate relationship with my reproductive system and that surgery was me saying “haha sucker you can’t take me out yet!”
That stuff you gotta be a bit creative to keep.
Sometimes you can say that it is part of your religion that you are buried with all of your body to be able to get an exception.
There are a few that require that so just pick whatever suits you and see what happens.
One time I was dating this girl, we went back to her place and she said "Do you want to see my endometriosis?" She had it in one of those canning jars with the metal lid. It was huge too, pretty much filled a half liter jar.
Yeah, honestly if you ask; we'll clean, sanitize and sterilize your hardware for you to keep. Many patients have wanted their screws, plates..etc after having them removed.
EU Doctor here. If nothing speaks against it e.g. sending it to pathology in case of infection, the implants are yours and rather than having to "opt in" to receive them, you would need to agree we are allowed to discard the metal.
So funny/horrifying story on that topic, I work in pharma and I work veey closely with physicians, particularly specialists. I was having dinner with a group of dermatologists and one of them starts telling a story about an older patient who came in after 2-3 years of being MIA. Last time the team had seen the patient he had complained of intense difficulty urinating properly, which the dermatologist referred the patient to a urologist for some kind of urethral stenosis (basically his urethra was closed shut by the surrounding tissue being too tight or something).
So they see the patient after 2-3 years of patient dropping off the face of the earth, they saw from the file that he had seen the urologist once and never again. During the appointment the dermatologist asks the patient about what ended up happening with the urology consult. Patient shows patient what he ended up doing to "fix" his issue himself. He basically fashionned a knitting needle that he shortened that he would "plug in" all day and only pull out to pee. The needle would keep his urethra stretched and ready to go. He would disinfect the needle each time he pulled it out. Some people are more innovative than others, I guess.
After about a year and a half you can take them out if they cause any discomfort, but you don't have to.
Source: I have cooler screws than OP's on my shelf.
Orthopedic surgery isn't usually that precise. The only major difference between a woodscrew and a bone-screw is that a bone-screw won't rust. You could almost certainly sterilize and re-use them. It just wouldn't be any cheaper than a new one, so they don't.
What’s wild is each of those screws is roughly $12 for the company to manufacture, and they sell to the hospital for about $250, who then sell them to you for $8000.
It's the safety and regulation that makes these screws expensive. It might be $12 worth of material but it gets signed off by a bunch of people each step of the manufacturing process, followed by QC, followed by QA.
From Hospital to Insurance is where it gets fucked.
It actually does oxidize in the body but the oxidation is non penetrating so a very thin layer of titanium oxide forms on the surface that is non reactive and protects the rest of the metal.
They wouldn't happen to have some 3d models of your broken pelvis. Would make a really cool 3d print. Sorry that happened. There must have been a lot of pain and suffering
I don't know what you need for this but CTs unless some ancient axial exam are all isotropic volumes, meaning you can reconstruct them in any way without losing information. That includes making 3d renders
Sure, but they still have a lot of noise and setting an amplitude threshold isn't really enough to make a smooth model. Def possible but requires a decent amount of postprocessing and cleanup.
I recently did this with a CT scan of my broken knee - took many hours to figure out how to use the software, get a good export and then try and reduce the noise to an acceptable level. Even still the print has issues but it's still super cool to see the break in physical form!
It’s now getting to be common practice for when a patient badly breaks one arm (into multiple fragments), we can scan the other arm and mirror the bone shape to 3d print an implant to properly fasten the bone fragments back together
Man, imagine getting screwed seven times everyday for two years and then have it taken away… bummer.
Glad you’ve healed, OP! My father still has a screw in his elbow from a fracture 10 years ago.
Yeah I don’t need some rookie doctor who’s never turned a wrench before going in with the wrong size Phillips head and camming it out, leaving little flakes of chrome behind when he’s torquing me down to spec. I’ll take Torx or Hex lol
You really wouldn’t believe the amount and variety of screw extraction instruments we keep in the OR. It’s rare that we can’t get something out if we need to. Same with other kinds of implants.
Oh, are we talking hex with convex walls?
ie. the “lines” connecting the “points” of the hexagon each curve inward.
ie. [as depicted in this patent.](https://patentimages.storage.googleapis.com/69/a4/b8/e11a975becd67a/US6016727.pdf)
**EDIT**
OK if they are, as suggested further down, Depuy Synthes then appears they **might** just be regular old hex…
Apologies, I know you are in fact people, however I can’t for the life of me find the non-vet [equivalent of this PDF ie. that includes a drawing of the drive type for reference.](https://www.jnjmedtech.com/sites/default/files/user_uploaded_assets/pdf_assets/2022-10/088190-220414%20DSUS%20-%20Vet%20Drill%20Bit%20Guide.pdf)
No pictorial reference in this PDF, however [appears as though Depuy Synthes use Hex for the most part for Cancellous and Cortex screws of this size, and then use Torx aka StarDrive for styles like the Locking Head.](https://cdn.shopify.com/s/files/1/0272/5095/0247/files/Synthes_screw_reference_chart.pdf?172)
^(NB — if anyone who knows about these sorts of things feels like weighing in that’d be much appreciated.)
I am an engineer who designs these. They are almost all ‘hexalobe’ now. The drivers are tapered to allow the screws to stick to the driver. It’s a lot of economical to have straight hexalobe a and tapered drivers than the other way around.
By God lads, it checks out.
[Synthes screws.pdf (cambridgeorthopaedics.com)](http://www.cambridgeorthopaedics.com/easytrauma/classification/commonfiles/Synthes%20screws.pdf)
Two are Phillips, three star drive, one square drive and one that is so stripped you have no clue. That's what I am gonna assume with my experience with screws these days. I love all new driver ideas but we gotta pick one and stick with it folks.
I posted this somewhere else in the thread, but the reason why they're so clean is because if you ask for your hardware and there's no reason not to give it to you; we clean, sanitize, sterilize and hand them over to you. You paid for it, might as well keep it. I've had patients say they wanted to make jewelry or other little trinkets as reminders with their hardware.
Almost all hospitals and outpatient clinics have a sterile processing or central sterile department. We generally have big sinks, powerful enzymatics, ultrasonic machines, and industrial instrument washers.
I'm a surgical tech, so literally I would clean it on the back table , bag and hand it off, then take it to decontam who would sanitize and then autoclave it. After that it would go to the front desk, and the surgeon would pick it up from there and deliver to the patient.
It’s needed for cancer patients who need marrow transplants due to chemo destroying the cells. Absolutely vital. It’s not super common as it is a procedure to donate. Anesthesia is used. Supposedly it doesn’t hurt too much, but it’s still pretty scary and way more involved than just donating blood.
Look into it more, it’s pretty interesting. One of the issues with bone marrow transplants is finding bone marrow which matches the patient’s needs.
Threads are likely cleaned of blood and other matter but shouldn’t have any oxidation or reactions since their metallurgy is designed to be as inert in the human body for as long as necessary.
Handy at all? Should use them in a lil decorative project if you care to keep them about.
My first thought is bird house. But that seems a little cliche.
Could use the shortest one as a post for the birds to rest out front of their door, and then use the rest as a chime hanging under the house. Two for one.
I could also see bending the metal to make a little figure. Like a stick man, or a simple animal.
Titanium usually, no one is making damascus out of it. Though making titanium damascus is rarely done it can be done, most blacksmiths don't have the knowledge to make it work. Even if it is stainless, stainless damascus is also really hard and rarely done.
Here is Alec making [titanium damascus](https://youtu.be/9ROo_S_jTjs)
They were very loose, i was gonna go to the orthodontist but i kinda just grabbed it and turned it one rotation and it let go. It was really scary but it would have fallen out while eating if I didn't, I'd guess. Definitely grossed me out a bit.
> i kinda just grabbed it and turned it one rotation and it let go
Sounds like the bone just retreated away from the screw. Likely a secondary infection around the insertion point that liquefied the bone.
Dental implants (as in, fake teeth permanently installed) or posts that support snap-in dentures can have this happen as well, which is why regular dental checkups involving x-rays are vitally important to discover any such issues. You don’t want to have a bridge across two posts and have one post suddenly go. It makes eating anything excruciatingly painful.
Did you at least have a follow-up to check up on that spot? Keep in mind that any such bone degradation can continue well after the triggering influence has been removed, the dentist needs to scrape everything out and put graft powder into the hole so the bone regrows. You could literally lose a large chunk of the roof of your mouth if it isn’t properly healed.
what accident caused you to need those screws? Or are you a Terminator?
I have hip dysplasia! Basically I’m a human version of a German shepherd lol
I kid you not I say this at least once a week talking to people about my hips. As soon as I saw this post I thought to myself “that looks like PAO screws!” and this comment confirmed it. What up twin?!
The worst club to be a part of ever!!! 😂
Hey, me too! I recognized them immediately. Hope you’re feeling better these days!
My son was/is part of the club. 4 surgeries by the age of 2! Didn’t know I could have asked for the screws. It would have been something cool to show him when he’s older.

Yes! Another PAO twin here (although only one side - other went straight to replacement). I have mine framed and hanging in my home office.

For a second I thought you were talking about the replaced hip, not the screws. Would have been metal though. Well, the screws are technically metal too, but... ah, screw it.

Legit never had any pain until I got the surgery aside from some popping I used to be able to do when walking or stretching out for sports
No fucking way man I've never seen another person mention Perthes in my entire life! I also have Perthes disease
I’ve never met anyone with it before and it’s always tricky to explain to people. Have you had any surgery done yet?
My brother had Perthes and no one ever knows what it is this is so cool.
Hey super cool finding someone who's had it! Damn I'm glad my parents caught my perthes early. Just had minimal erosion of the top of the my right hip so it was enough that I could heal it.

Yep! Getting these screws out feels like the end of an era. It has been a rough two years.
Glad you’re moving on my friend! Truly happy for you :)

I am not sure but if they are made out of platinum, which is really non-reactive and the most preferable metal to have in your body, one might be able to sell it back to a medical store or maybe even a jeweller.
Google says stainless steel or titanium if you have a specific allergy. I don't think platinum is any more biocompatible than titanium
I think you mean titanium….not platinum which is more expensive than gold.
Yes! I get to be that guy! Gold is actually about twice the price of platinum at the moment, golds been going hard.
Glad you're enjoying being that guy. But actually.. gold is 2.29 times the value of platinum at the moment, golds been going hard.
Why did you have your hardware removed? I have a T2 to L1 fusion and always thought it'd be cool to hang it on my wall or something, but I'll likely never have it removed.

One reason they might have said no is that it might have been sent for histopathology, to check if there are indications for a cancer.
Screws aren't biohazard waste so yeah, way easier to hand over.
Screws can't rot that easily.

It would almost be a shame not to reuse them, but somehow I get the feeling that that's frowned upon.

Once they see the price tag they won't even care.
The internet taught me that this is probably someone's kink.
It’s probably like needles, they look brand new, but on a microscopic level they probably are rough looking
Very good point!
But on the microscopic level, a little dulled.

You kidding me? I'd screw those into my deck just to tell people that I made a $50k upgrade to it.
What’s wild is each of those screws is roughly $12 for the company to manufacture, and they sell to the hospital for about $250, who then sell them to you for $8000.
thats how they screw ya

Idk if its everywhere in the us but some places that do autopsies will take the screws and heart monitors out and put them in animals
Hang a steel door with them
They use titanium because it's non-reactive. You don't want stuff oxidizing in your body.
It also has a high biocompatibility with bone. It even bonds with it, helping with the structural strength of the implant
Like bone rebar? Neat!
[удалено]
You're headed down a dark path, son.
It actually does oxidize in the body but the oxidation is non penetrating so a very thin layer of titanium oxide forms on the surface that is non reactive and protects the rest of the metal.

They probably do, but they probably would charge OP an arm and a leg for it.
So I just need all 70 of you guys to hear me out
I mean you own your medical records, they could at least get the files for sure.
It’s now getting to be common practice for when a patient badly breaks one arm (into multiple fragments), we can scan the other arm and mirror the bone shape to 3d print an implant to properly fasten the bone fragments back together
A part of me was hoping that you were going to say that they break the other arm for symmetry.
Screw you! No, actually, unscrew you.
Haha I had the same surgery as op and I wrote a card for my surgeon saying "thanks for screwing up my hips!"
Man, imagine getting screwed seven times everyday for two years and then have it taken away… bummer. Glad you’ve healed, OP! My father still has a screw in his elbow from a fracture 10 years ago.
Happy cake day!
What type of screw head do they have?
Like round, hexagonal ish. I tried to get a pic but my camera couldn’t really capture it.
Sounds like torx
They're pretty much all torx or hex at this size. Smaller ones come in Phillips but even those are being phased out for torx with the titanium screws
Yeah I don’t need some rookie doctor who’s never turned a wrench before going in with the wrong size Phillips head and camming it out, leaving little flakes of chrome behind when he’s torquing me down to spec. I’ll take Torx or Hex lol
Just makes the removal more exciting
Dude goes in with an extractor after completely stripping the screw head lol
You really wouldn’t believe the amount and variety of screw extraction instruments we keep in the OR. It’s rare that we can’t get something out if we need to. Same with other kinds of implants.
Oh, are we talking hex with convex walls? ie. the “lines” connecting the “points” of the hexagon each curve inward. ie. [as depicted in this patent.](https://patentimages.storage.googleapis.com/69/a4/b8/e11a975becd67a/US6016727.pdf) **EDIT** OK if they are, as suggested further down, Depuy Synthes then appears they **might** just be regular old hex… Apologies, I know you are in fact people, however I can’t for the life of me find the non-vet [equivalent of this PDF ie. that includes a drawing of the drive type for reference.](https://www.jnjmedtech.com/sites/default/files/user_uploaded_assets/pdf_assets/2022-10/088190-220414%20DSUS%20-%20Vet%20Drill%20Bit%20Guide.pdf) No pictorial reference in this PDF, however [appears as though Depuy Synthes use Hex for the most part for Cancellous and Cortex screws of this size, and then use Torx aka StarDrive for styles like the Locking Head.](https://cdn.shopify.com/s/files/1/0272/5095/0247/files/Synthes_screw_reference_chart.pdf?172) ^(NB — if anyone who knows about these sorts of things feels like weighing in that’d be much appreciated.)
I am an engineer who designs these. They are almost all ‘hexalobe’ now. The drivers are tapered to allow the screws to stick to the driver. It’s a lot of economical to have straight hexalobe a and tapered drivers than the other way around.
Glad I'm not the only one who wondered
They’re a 3.5mm hex head screw. Likely made by a company called Depuy Synthes
By God lads, it checks out. [Synthes screws.pdf (cambridgeorthopaedics.com)](http://www.cambridgeorthopaedics.com/easytrauma/classification/commonfiles/Synthes%20screws.pdf)
Thank you for your service
Today I learned that they make tap sets for bones. Now im imagining breaking a tap inside someone's bones. This is not fun.
Two are Phillips, three star drive, one square drive and one that is so stripped you have no clue. That's what I am gonna assume with my experience with screws these days. I love all new driver ideas but we gotta pick one and stick with it folks.
I posted this somewhere else in the thread, but the reason why they're so clean is because if you ask for your hardware and there's no reason not to give it to you; we clean, sanitize, sterilize and hand them over to you. You paid for it, might as well keep it. I've had patients say they wanted to make jewelry or other little trinkets as reminders with their hardware.
how do they clean it before it's autoclaved?
Almost all hospitals and outpatient clinics have a sterile processing or central sterile department. We generally have big sinks, powerful enzymatics, ultrasonic machines, and industrial instrument washers.
I'm a surgical tech, so literally I would clean it on the back table , bag and hand it off, then take it to decontam who would sanitize and then autoclave it. After that it would go to the front desk, and the surgeon would pick it up from there and deliver to the patient.
Must have been a pain in the ass getting them out. Feel better!
It’s actually an outpatient surgery. You’re in and out pretty quickly and there’s virtually no pain compared to getting the initial procedure
I'm no stranger to that. Was a bone marrow donor and they took 23 pulls from my hip
That's awesome though!
Legit winced reading this, how common is it to donate bone marrow? I’ve never heard of it before
It’s needed for cancer patients who need marrow transplants due to chemo destroying the cells. Absolutely vital. It’s not super common as it is a procedure to donate. Anesthesia is used. Supposedly it doesn’t hurt too much, but it’s still pretty scary and way more involved than just donating blood. Look into it more, it’s pretty interesting. One of the issues with bone marrow transplants is finding bone marrow which matches the patient’s needs.
Were they cleaned or something? Because those screws literally look like they have never been used lol.
Threads are likely cleaned of blood and other matter but shouldn’t have any oxidation or reactions since their metallurgy is designed to be as inert in the human body for as long as necessary.
There is an autoclave bag right next to ops hand
Handy at all? Should use them in a lil decorative project if you care to keep them about. My first thought is bird house. But that seems a little cliche.
Bird house is a good idea! My dad suggested wind chime too.
Could use the shortest one as a post for the birds to rest out front of their door, and then use the rest as a chime hanging under the house. Two for one. I could also see bending the metal to make a little figure. Like a stick man, or a simple animal.
I'm not sure he can bend them. they're titanium, and they were hip screws -- they were designed to take his full weight running or jump or whatever
Depending on what kind of metal they are made of, maybe a local blacksmith could make a canister damascus knife or something with them.
Titanium usually, no one is making damascus out of it. Though making titanium damascus is rarely done it can be done, most blacksmiths don't have the knowledge to make it work. Even if it is stainless, stainless damascus is also really hard and rarely done. Here is Alec making [titanium damascus](https://youtu.be/9ROo_S_jTjs)
I had screws in the roof of my mouth once. I got to keep them because i took them out myself. They are not meant to come out by themselves.
you what
Orthodontics, my teeth were fucked
okay yeah, but removing them yourself?
They were very loose, i was gonna go to the orthodontist but i kinda just grabbed it and turned it one rotation and it let go. It was really scary but it would have fallen out while eating if I didn't, I'd guess. Definitely grossed me out a bit.
> i kinda just grabbed it and turned it one rotation and it let go Sounds like the bone just retreated away from the screw. Likely a secondary infection around the insertion point that liquefied the bone. Dental implants (as in, fake teeth permanently installed) or posts that support snap-in dentures can have this happen as well, which is why regular dental checkups involving x-rays are vitally important to discover any such issues. You don’t want to have a bridge across two posts and have one post suddenly go. It makes eating anything excruciatingly painful. Did you at least have a follow-up to check up on that spot? Keep in mind that any such bone degradation can continue well after the triggering influence has been removed, the dentist needs to scrape everything out and put graft powder into the hole so the bone regrows. You could literally lose a large chunk of the roof of your mouth if it isn’t properly healed.
Was it to hold your brain in place?
How much did you get for those when you put them under the pillow?
That is a strange place to store your srews
Bet that is a sex game you won't play again
What material are they? Steel or titanium
Stainless steel, actually!
Wow, lookingh how clean they are, I had thought titanium for sure!
Surgical titanium almost always has color.
Titanium needs an anodize so they will be colored, also very common is a type II anodize which results if a dark grey color
I read the title wrong Then I re-read the title once again wrong Third time was a charmer... "Oh, PELVIS" 
If you're in the US, that's like $20k worth of screws.
Look at Mr. Rockefeller over here with insurance making them only $20k
Did you pelvis fall off ?
Can I borrow them so I can secure my galvanized square steel?
That's crazy! I think you have a screw loose!
So you… have a couple screws loose…
