Huh, TIL about bone cement. I was curious so I looked it up, and for those who are also curious, it appears to typically be a mix of PMMA (i.e. plexiglass) and its monomer MMA (although some radically different materials have been developed). You mix the goo and it turns to dough and then eventually hardens into, well, plexiglass. The SDS for MMA doesn’t seem that bad, so there must be more to it than just that.
Thanks for sharing this! I never knew plexiglass was biocompatible-ish and was used in this way.
99% of the cases that use bone cement I’ve been in, in all of the hospitals I’ve worked at, have used that specific product. With the exception of a shoulder surgeon I worked with who liked this goopy blue shit that got everywhere.
In any case, that stuff is, uh… pungent. Like even when I’m not in the ortho room, if I want to check on how far along their case is, I don’t even need to actually look in the OR - getting near the room is enough to tell me whether or not the implants are in, indicated by the presence or absence of that smell within about 15-feet of each entrance to that OR.
Pregnant or not, I can’t imagine breathing that shit every day is doing us any favors. >_>
…and that’s ignoring electrocautery smoke, radiation, and all the biohazardous shit we’re exposed to in there. I swear in 10 years we’re going to be featured in cautionary training videos about what happens when you don’t use whatever latest-and-greatest technique is being pitched to keep that shit out of our lungs.
looks like it’s the monomer of plexiglass with hydroquinone to prevent premature polymerization and N,N-dimethyl-p-toluidine which is like, an adhesive or something? The latter is probably the issue.
Yeah, seems like people working in medicine have a rough time of it. My sister works in a cath lab and I worry about her exposure levels sometimes. I know she wears a dosimeter but like, man, it’s a lot of X-rays.

Here’s the specific stuff I’m familiar with:

Ahhh, hell yeah time to dig for a SDS!
