Bone remodeling and repair

- Опубликовано: 8 фев 2025
- What is bone remodeling and repair? Bone remodeling is when old, brittle bone tissue is removed or resorbed and gets replaced by new bone tissue. Remodeling also occurs when reshaping your bones after a fracture or when repairing micro-cracks which form during ordinary activities, especially when your bones are under stress, like after lifting heavy weights.

why this gave me more understanding than my college..i love it
Focused on lecture rather than Girls 😂😂😁
Willl my bone density will grow after quitting drugs? I am 23+.
Because you are fool 🤣
Great video. ties everything together nicely. Decided to review bony remodelling today and fascinating what you can pick up again on revision. Initially when learning about bony remodelling I never really thought about the significance of RANKL , but with drugs such as Prolia , a RANKL inhibitor , it becomes obvious as to why the fundamental understanding of the physiological processes is vital to clinical practice with associated pathological states such as Medication related oseteonecrosis of the jaws. Many thanks.
Finally understood the mechanism after 5 retake. love this type of resource, really insightful and articulate.
We're glad it helped, Dhruv! 🙏🏼
I've searched more than 1 hour for a video like this, thank you so much 😍 this sums up everything i want about bone tissue 👏
Hi Eva, Glad it was helpful!
Read your bible! (KJV, preferably) ♥
Bone remodeling in short:
-Osteoblast release M-CSF & RANKL → Convert monocytes into osteoclasts → ↓ Bone mass
-Osteoblast also release Osteoprotegerin (OPG) → OPG will inhibit RANKL → ↑ Bone mass
The illustrations are fabulous
I would have loved to see more infromation about hormones and their influence on bone remodelling, such as the osteolytic effect of cortisol and such. An all-in-one video of what hormones affect bone remodelling.
This was really helpful plus the illustrations are adorable!! Thank you so much.

Simple yet deep and well explained. Thanks a lot. Please make more animationlike this. I really appreciate it. Gbu all team!
Thank you Mikhail for that wonderful feedback!
One of the best video on bone remodeling
Wow, thanks for that feedback!
This is the perfect video for this subject. Thank you so much!
Glad you think so!
Great visuals and wonderfully concise and explanatory! Thanks so much!
You're very welcome! Thanks for letting us know!
Thank you for sharing. Please we would love to see more videos like this
Wow, this is really informative. Thank you! I lost 2 Parathyroids after a messed-up operation. Still don`t know how to deal with this, but trying and learning. 😰
Sorry to hear that. Katharina. We hope you're doing better now. 🙏🏼
Watching this on my way to my test. Thank you
We hope it went well! 🙏🏼
I love you soo much , more than you could imagine osmosis ❤❤❤❤❤❤
Thank you! 💕
What a vivid way to present such hard topic. Thanks a lot !
Thanks for your wonderful comment! 🥰
I think there is a mistake at 2:41. Myeloid progenitor cells come from hematopoietic stem cells, not lymphoid stem cells.
Thanks for pointing this out! Our team will be reviewing this information and update the video as needed. 🙏🏻
Wow thats so helpful...Thanks alot. In the midst of confusion and infodemic, its like a hopeful rays.
Glad it was helpful! 💫 🥰 💖
Great video! Helped me a lot!
Parathyroid gland stimulates osteoclasts (not osteoblasts) for bone resorption to occur. Small mistake at 5:05.
That was exactly what was needed
Another great video by the Osmosis Team! Thank you!
Thank you too! 🙏🏼
Amazing. Now i remmeber the core of a complicated process in our body. TKs a lot
Glad to hear that, Minh! ❤️
That's wonderfully explained..Made understanding very clear just in 5 min..
Thank you so much
Glad it was helpful, Foram! ❤️
At 50 years old I started playing basketball again almost everyday. I had a lot of bone pain in my shins - upper tibia. They felt as if they were hollowed out through time and now they were bearing too much stress. I didn't give up, kept playing but I was scared it would lead to some injury. Amazingly, after a while the pain went away. I guess this is what was happening, very interesting! From the start of it all it was my feet and ankles at first, then it moved up to my knees, then hips. Now, I have shoulder pain. It feels like a rotator cuff problem but going at it playing basketball doesn't seem to help so far. Resting it and altering my sleeping position has helped some but it feels like I have hit the limits of my age unfortunately.
as a medical student, I admire and appreciate all your work
Thank you! 🥰
I'm gonna send this video to my professor 💀✌️
Dear Osmosa,,, please make a video about closed fracture.. thanks a lot.
Medical college life is easier with osmosis! 💗💗
Glad to be of help! 😊
Very brief vidio......Thanks alot
Very clear and straight forward
Thanks, Mary! 👍🏼
Great ❤❤❤❤❤🥳🥳
Where's repair???
It starts at 4:20
Well explained 👏👏👏, thank you so much 🙏
Glad you think so, Ramokunupi! 🥰❤️🙏🏼
❤️❤️.. plz make a video on osteoporosis
Great explanation ma sha Allah!
Thank you!!! It makes so much sense now!
Glad to help! 😊
Thanks Bro! this really helped me.
the best explanation 😍
Thanks, Dunya! 💕
So I have a question is there anything I can take to help my body strengthen my bones? I did have a mild fracture and a lot of people were saying to take vitamin D, calcium and vitamin C. But after watching this video on doing some more research, I’ve determined that’s not a great idea.
Thank you!
Awesome explanation. Loved it.
Thanks, Chris! 😊
I wish my actual lecture was that easy with less deatails :(
Best summary ❤
Thanks! 😊
U ppl.arw.doing such a great teaching
..thanks a lottt
Hi Navyashree, thank you, we're glad you find our videos useful! :)
My daughter had PAO surgery. The coverage is good no doubt. She still has pain and is very thin, could bone remodeling be an issue?
When the bone is getting remodeled due to stress fracture , does it add 2-3 inches in height growth . When fully recovered
why there is resorption in one side and the deposition in the other side not in the same side ?
You are a life saver ❤️
Always glad to help, Muhammad! 🥰
@5:03 I think you’re mistaken. Shouldn’t the osteoclast be reabsorbing bone to release calcium in the bone?
Hi Kevin! Thanks for pointing this out. We've notified our team about this so they can have the information reviewed. 😊
excellent job
Many thanks! ❤️
This is so good but i dont know english well so it was hard to understand😭😭 but tysm anyways that helped a lot🥹🫶
Thank you very much
I think there is a small mistake, yellow bone marrow does not produce blood cells as was indicated in the video. That is actually red bone marrow typically found in the epiphysis
Thank you so much for bringing this to our attention, Grant! I will be sure to pass this along to my colleagues on the Content Team so they can check the details with our Chief Medical Officer. 😊
great vid
Thanks, Hanan! 😊
Great video, thank you
You're welcome, Euge! 🥰
Thank u! ♡
I have a question please regarding Wolff's Law: if we say that
Applied pressure results in bone resorption, while applied tension results in bone formation.
is that correct or not?
Thank you. ❤
You're welcome 😊
thx! it help me a lot

how long is it ? how long the process go ?
Amazing ♥️♥️♥️♥️ thank you very much
You are the best ❤️
Aww.. thank you Kiaan! ❤️
Wow amazing explanation
Thank you! ❤️
How about left humerus? How many months it takes before healing?
What do you think about bonesmashing?
This is amazing
Excellent presentation , but as far as I know osteoclasts doesn't produce COLLAGENASE , it is produced by osteoblasts actually , bone resorption by osteoclasts at it's clear zone (at ruffled borders) mediated by carbonic anhydrase , secondly it pump out hydrogen ions( after CO2 hydartion - H2CO3 formation - breakdown into Hydrogen and carbonate ions -then pump out hydrogen ions) which lowers pH , lysis of collagen in acidic media , which leads to bone resorption , Plz tell me if I m wrong
Are these cytokines that these cells use to signl or use as a communication to start og stop a process?
What is the duration of this process
Thank you so much this is amazing
You're so welcome! 💖
Pretty helpful! Thanks!
So helpful!
Glad it was helpful! 💖
Does bone remodelling make the bone stronger and bigger like a muscle
Perfect👌Tnks✨🌸
Thank you.....very usefull video
Welcome! 😊
Thanks a lot !!!
We hope our video helped! 🥰
very appreciable
Thanks!
excuse me but do you have a video explaining mechanism of healing of bone's fracture?
Really nice
Thank you! 🥰❤️🙏🏼
This didn't really explain how the bones know what shape they're supposed to be. I am particularly interested to know why spinal stenosis doesn't reverse itself relieving pressure on the spinal cord.
Understand thanks. A lot
Happy to help 🙏🏼
what if person diabetic? how will heal
I had 12 years ago a femure fracture very ugly caused by a tumore. I had surgery ofcourse the doctor said he clean everything there very good and he put me a metal plate wich I still have now and than I had the chimioterapy treatment. After 3 years I started to go slowly to gym and workout slowly but still even now after years I still cannot do the exercises for legs I did before the fracture because some pain during workout. You think the femur after this damage has healed properly? I will like your opinion also. Thank you
Amaaaaazing !!!!
🙌🏼 💕 ✨
Does this process take place in the skull bones like the jaw or cheekbones?
Good question
Awesome
So...is bone death reversible?
woow I love this one, thank for amazing video :)))
Glad you like it, Siti! 🙌🏼
Great
amazing❤❤❤❤❤❤❤❤❤
This is nice
