Thanks to all who responded.

Responses to my posting yesterday are listed below which revealed two major points:

1) there is ample interest in this topic

2) It will be extremely difficult to acquire paediatric cadaveric tissues for research

An additional question for the list.... Is there anything that we can do as a group to educate the public about the need for parents to offer donations which can lead to decreased injury for other children, even after the untimely loss of their own child? Example... could a petition be sent to CPSC or FDA in an attempt to educate them about the need for paediatric cadavers for injury research?

Do you have more information about your research? We should keep in contact. Below are my publications in this area. I can send you pdfs if you like.

Well, I don't know anything about ped failure loads, but BC Deemer, a pretty far along PhD student over in RST at one point in his long research career investigated ped falls and developed computer models and simulations to evaluate whether fractures could occur in a given 'fall' situation so he would have to have some information about loading tolerances. I'm not sure he is on the list to see your message, but you can try emailing him

Andrew Mahar wrote: You can contact NDRI based in Philadelphia on this issue. However, I have never been able to obtain pediatric specimens in amounts to actually conduct a study. We do pediatric spine, trauma and hip research and nearly all of our data comes from experimental or numerical modeling. Jason R. Kerrigan wrote: I would be surprised if you were able to legally obtain any pediatric post mortem tissue in the United States. As you are likely aware, there is amassive need for pediatric injury criteria and constitutive models in the automotive safety field for dummy/computational model development/improvement. However, even universities with long histories of research exemplifying the highest technical (and ethical) standards are virtually unable to obtain such tissue. However, this remains a dynamic situation and thus I would be interested inany responses you get.
Michael Dahl wrote: You're going to have a hard time finding pediatric specimens. Research we've done on spine injuries using pediatric specimens were mostly done using baboons, and the data were then multiplied by a scaling factor to approximate children. We were able to validate our scaling factors by testing a handful of pediatric tissues, but each specimen had to be personally obtained by discussing the research with parents who had lost their children to accidental circumstances or suicide. Since the research was for car crash safety, a couple families decided that it was a worthy contribution. I would look into an animal model, since there is a lot of data on scaling already, it is cheaper, and easier to obtain.
