Bone remodeling and repair

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

[@kashifkhan7379]

Focused on lecture rather than Girls 😂😂😁

[@This_or_Thatx1]

Willl my bone density will grow after quitting drugs? I am 23+.

[@amnafayyaz6768]

Because you are fool 🤣

[@bayannasseral-harrasi6089]

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

[@senankavanagh2382]

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.

[@Dhruvrajpal-x2y]

Finally understood the mechanism after 5 retake. love this type of resource, really insightful and articulate.

[@osmosis]

We're glad it helped, Dhruv! 🙏🏼

[@evakhwaiss7484]

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 👏

[@osmosis]

Hi Eva, Glad it was helpful!

[@abel6298]

Read your bible! (KJV, preferably) ♥‎

[@mariamriaz2311]

Where's repair???

[@peednas711]

It starts at 4:20

[@uhlezza]

This was really helpful plus the illustrations are adorable!! Thank you so much.

[@degodaniyt6557]

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.

[@rasheshdas]

The illustrations are fabulous

[@infiredpumpkins1970]

It's crazy how well osmosis explains stuff 😭😭 life saver

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. 😰

[@osmosis]

Sorry to hear that. Katharina. We hope you're doing better now. 🙏🏼

[@melindaaa1404]

This is the perfect video for this subject. Thank you so much!

[@osmosis]

Glad you think so!

[@hmzzrg5045]

I think there is a mistake at 2:41. Myeloid progenitor cells come from hematopoietic stem cells, not lymphoid stem cells.

[@osmosis]

Thanks for pointing this out! Our team will be reviewing this information and update the video as needed. 🙏🏻

[@kuengatshomo7396]

Wow thats so helpful...Thanks alot. In the midst of confusion and infodemic, its like a hopeful rays.

One of the best video on bone remodeling

[@osmosis]

Wow, thanks for that feedback!

[@DrDY-us4rg]

That was exactly what was needed

[@MinhNguyen-li2eb]

Amazing. Now i remmeber the core of a complicated process in our body. TKs a lot

[@osmosis]

Glad it was helpful, Foram! ❤️

[@charmimgshahnaz7455]

Dear Osmosa,,, please make a video about closed fracture.. thanks a lot.

[@thomasbays8292]

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?

[@ADAPTATION7]

Parathyroid gland stimulates osteoclasts (not osteoblasts) for bone resorption to occur. Small mistake at 5:05.

[@fevenre4969]

Very brief vidio......Thanks alot

[@marysakala1079]

Very clear and straight forward

[@osmosis]

Thanks, Mary! 👍🏼

[@nothing_fancy692]

Thank you!!! It makes so much sense now!

[@osmosis]

Glad to help! 😊

[@gauravgupta174]

When the bone is getting remodeled due to stress fracture , does it add 2-3 inches in height growth . When fully recovered

[@LiamGarthwaite-j1q]

Does bone remodelling make the bone stronger and bigger like a muscle

[@shelbyrodrigues]

can you please make a video on the 2 types of bone ossification and the stages for each!!! I canot find any animations on youtube

[@osmosis]

Thanks for your recommendation! Our team will be taking this into consideration. Have a wonderful weekend! 💖

[@1cloudshinobi]

What is the duration of this process

[@ramokunupisekgwaila5033]

Well explained 👏👏👏, thank you so much 🙏

hi, could you add the bibliography used to make this video? it was so useful to me and i'd like to read sources too

[@osmosis]

[@munishgupta2226]

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

[@sachinrathore28]

Wow amazing explanation

[@osmosis]

Thank you! ❤️

[@nihalgaber3403]

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?

[@ruveydalipa]

This is so good but i dont know english well so it was hard to understand😭😭 but tysm anyways that helped a lot🥹🫶

[@hananmohamed9302]

great vid

[@osmosis]

Thanks, Hanan! 😊

[@arizarichie9446]

how long is it ? how long the process go ?

[@wifaqjaborialbazy-4405]

excellent job

[@osmosis]

Many thanks! ❤️

[@grant4360]

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

[@osmosis]

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. 😊

[@ayamohammed7753]

Great explanation ma sha Allah!

[@mike.m4621]

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

[@CHRISGURJAR]

Awesome explanation. Loved it.

[@osmosis]

Thanks, Chris! 😊

[@khushishah2130]

❤️❤️.. plz make a video on osteoporosis

[@Vikrant-7812]

I'm gonna send this video to my professor 💀✌️

[@KhadigalMohamed]

Great ❤❤❤❤❤🥳🥳

[@paltrygorilla9151]

Thanks Bro! this really helped me.

[@UHFStation1]

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.

[@dunyaimanova9207]

the best explanation 😍

[@osmosis]

Thanks, Dunya! 💕

[@alkynesofatoms9315]

Great, thank you.

[@halobium3513]

excuse me but do you have a video explaining mechanism of healing of bone's fracture?

[@azouz5675]

why there is resorption in one side and the deposition in the other side not in the same side ?

[@jayarramos2300]

How about left humerus? How many months it takes before healing?

[@maja0247]

Thank you so much this is amazing

[@osmosis]

You're so welcome! 💖

Are these cytokines that these cells use to signl or use as a communication to start og stop a process?

Thank you. ❤

Excellent ... well done ...

[@osmosis]

Thank you, Mahu! 🙏🏼

[@rasheshdas]

Thank you very much

[@Bassman7608]

@5:03 I think you’re mistaken. Shouldn’t the osteoclast be reabsorbing bone to release calcium in the bone?

[@osmosis]

Hi Kevin! Thanks for pointing this out. We've notified our team about this so they can have the information reviewed. 😊

[@Kiran.2020]

You are the best ❤️

Does this process take place in the skull bones like the jaw or cheekbones?

[@karenk3986]

Good question

[@vijayramaraju3522]

Hello Sir, i had an small accident and 5th metacarpal was fractured, and it's just in position, doctor said, no need for k-wire , just split is enough for 6weeks. 2weeks back split is removed, now 2months completed, but fracture line still visible, how long it will take to go off fractured line on x-ray, and I'm afraid of do physiotherapy, because when I'm doing physiotherapy some pain on fracture site. Give me some suggestions, please, thanks in advance....
