To me it seems as though step 1 is moreso describing subperiosteal ossification as opposed to the internal endochondral ossification, anyone else agree? I'm having a hard time differentiating the two and this seemed to make that complication a bit worse for me - nonetheless, a very helpful video!

Nicely done. However, a minor correction - your sesamoid bones (such as your paired patellae) do not form via endochondral ossification. They form by intramembranous ossification.

what is central clearing ?

@gibcote 8 жыл бұрын

Once the chondrocytes start dying, you've mentioned that a central "clearing" begins to appear as the calcified matrix begins to deteriorate. Does all of the matrix get disintegrated? Or parts of the calcified matrix are retained and provide a scaffolding to the osteoblasts to secrete osteoid? Please help.

@Medictutorials 8 жыл бұрын

Hi Neely, you can think of the osteoblasts following the cartilage border as it deteriorates. This central clearing is what will become the medullary cavity, this is where we house yellow bone marrow, no osteoid type cells are there at all in the much later stages. I hope this answers your question, all the best!

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 crack 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....

I thought cartilage was a vascular. In order for blood vessels to be present there needs to be channels?

@Medictutorials 9 жыл бұрын

Mature cartilage is avascular, correct :). But as with any building process in the body, temporary vascularisation helps with delivery of essential components. Once the whole process is complete, the only component of the bone that has direct nerve and vascular tissue is the bone itself.

@leapofthefrog 8 жыл бұрын

+Medic Tutorials It's at about 3:57.

@Medictutorials 8 жыл бұрын

+leapofthefrog Ah yes I see where you're at :). It's definitely the chondrocytes that secrete in this phase. They are not sending a groth message as such, just releasing intracellular components that cause matrix hardening and subsequent chondrocyte death due to lack of nutrients. You can think of it as an extremely tightly regulated form of controlled cell death.
