For some reason, this did not go through when I sent it about 20 minutes ago... (At least I did not get an acknowledgement.)

The article is Journal of Biomedical Materials Research 21:1375 (1987). An editorial appears at JBMR 23:1243 (1989) and an exchange of letters at JBMR 23:1367 (1989). The letters document a significant effect of formalin fixation on push-out strength. The push-out strength appeared to double if the bone was fixed in formail before testing.

Hope this helps.

There was a discussion of this subject in some letters to the editor with follow-ups in late 1980's (sometime between 1987 and 1989) in the Journal of Biomedical Materials Research. I have tried to quickly find the information but didn't find it. It related to a push-out test of cylindrical specimens from bone which had been fixed in formalin. The writers believed that the formalin caused the organic portion of the bone to shrink around the specimens and enhance the push-out strength in the study. I believe the authors responded and provided a defense of the techniques used. The original article has as one author Paul Serekian and I think deGroot was another author.

If I am able to find the information, I will post the reference.

Dear colleagues,

Does anyone know what effects storing bone in formalin has on its
mechanical properties??

I will post a summary of all responses.

Thank you for your help
