Histopathology Bone--Osteoarthritis, subchondral cyst

[drashoksinghal100]

We have treated more than 600 cases of osteoporosis and osteoarthritis in past 7-8 years without any surgery with great success .Only with braces and PEMF bed and it only cost about 1/5 th of surgery .

Thanks for the explanation, it really helped.

With osetoarthritis don't you normally see thickening of the subchondral bone or subchondral sclerosis? Because the cartilage of the joint has been eroded the subchondral bone is subjected to higher forces thus we see somewhat of a disorganised hypertrophy of the subchondral bone ... I say disorganised because it's not aligned like corticol bone it is more of a "scarring" of bone (even though bone regenerates - subchondral sclerosis = scarring of subchondral bone, so this bone is not as strong).

You made me laugh at the beginning of this. :D

this is a great contribution to medical education. To mine at least!

Thanks. This is just great!!!

Thanks - this is great.

Very informative thank you.

Thanks for the info I am 28 and just found out my right pain is a subchondral cyst. I have been researching and found there is nothing I can do. Could this have anything to do with me being 6'7 250lbs?

[bbbbbb222222]

why do these things appear? the cyst i mean

[WashingtonDeceit]

well, think of spicules of bone in which osteoclast activity exceeds oseoblast activity, i.e., increased resorption like osteoporosis, wouldn't cysts eventually form?

[bbbbbb222222]

ok, thanks for your reply

[grilledcheesemmm]

Is there such as thing as a psuedocyst in OA? Are these different than subchondral cysts? THANK YOU!

[WashingtonDeceit]

to the best of my knowledge

they aRE THE same

[Nilyentaraka]

Can cysts on the bone develop independent of osteoarthritis, and if so, are they an indication of early arthritis?

[WashingtonDeceit]

anytime bone resorption occurs locally or systemically, the chance of a "cyst" developing is always present, with thinning and resorption of spicules, even INDEPENDENT of classic "osteoarthritis"...great question

[andy372]

By the way, your videos are amazing for medical training. Thanks.

How often do you see subchondral cysts and what are the most common locations?

[WashingtonDeceit]

subchondral cysts are VERY common in osteoarthritis by virtue of the fact that

the thinning of the bone spicules results in a "confluence" of the interosseous spaces, i.e., "cysts"

ironically the "cysts" really do not have a "neoplastic" or "tumorous" character because they are inside bone!

Hi, Do people with subchondral cystic foci near the ankle usually require surgery or can you just drain it? or rest it?

[WashingtonDeceit]

me!

wdc is a pathologist
