Hi everyone! For bone graft cortical/cancellous there are various sizes available . The one that I usually buy is 250-1000um . Other options are 125-500 . Can someone please explain when to use what size of graft?
Thank you !
Its sort of like driving a Ford vs a Chevy or Dodge…….. they will all get you to the finish line its just operator preference. I am sure others will disagree with this oversimplification but these products are all just space fillers so the body can lay down the real thing. I personally use 250-1000um as that is my preference but I have used the other particle sizes as well and can’t tell a difference other than it looks different in the jar…

Thank you Dr Scotty for your explanation!
I appreciate it
This is a great question and something we were just working on writing up by gathering all the research. Basically, the research (not large scale studies, just a few small scale studies) has shown that small particles (less than 125um) may resorb too quickly before adequate new bone form, but at the same time larger particles (greater than 1,000um) had less bone formation. This has led the industry to believe that the ideal particle size is somewhere between 125 and 1,000, that’s where they get the 250 - 1,000. n general nearly all tissue banks in the US, have settled on 250-1000 for Particle size, and they don’t really manufacture much in other sizes. Will 125-500 work? Probably. I think anything above 125 and less than 2000 would work.
