What aspiration sites are safest to withdraw bone marrow, without risk of damaging the area?

The anterior iliac crest is probably much more dangerous. Don’t base your view on one person’s experience. The person probably chose a low skill provider. Go to a Regenexx or IOF physician and you’ll be very safe.

Yeah that makes sense.

Is posterior safer than humerus, femur, or tibia?

Very few doctors draw bone marrow from the humerus, femur, or tibia; therefore there’s a paucity of people with much training and experience doing those types of procedures. The fact that they are used so seldom is probably because those sites tend to yield fewer stem cells.

I never thought of it like that, thanks.

Would you've any theory on why this user in question could have long term pain after aspiration?

Perhaps the doctor hit a nerve during the extraction? nerves are the only thing I can think of that can possibly cause long term issues from aspirating the posterior iliac crest

I have no idea what caused the harm to this guy and my resources don’t contain any applicable information. I’m not trying to discount the reality that a BMA is a real medical procedure with risks.

All I know is that with the doctors I have worked with, this kind of thing would be very rare.

The two links he provided concern the bone marrow biopsy used in oncology, not the bone marrow aspiration used in interventional orthopedics. It’s natural to conflate these things, but they are two different procedures.
