Distinguishing between perimortem and postmortem fractures: are osteons of any help?
Abstract
The distinction between perimortem and postmortem fractures in forensic anthropology is still a frequently unsolved issue. In the present study, we try to verify if there are differences in the pattern of osteon fracturing between fresh and dry bone which could be used for such a diagnosis. Fresh and dry long bones were fractured by a hammer at the mid-shaft perpendicularly to the long axis of the bone and the fracture margins examined under a light microscope as undecalcified sections. Examination of 982 osteons (505 fresh, 477 dry) showed that twice as often the fracture line crosses the osteons as opposed to travelling around them, independently of whether the bone is fresh or dry. Statistical analysis confirmed that there was no significant difference between fresh and dry bone. This seems to imply that osteon fracture pattern cannot help in the diagnosis of perimortem versus postmortem bone fractures. Further research however must be performed concerning fast and slow energy dispersal which may have an influence on the type of fracture inflicted.

So far, there has not been a focus on osteonal microcracking patterns in relation to trauma type but only literature on BFT cases and trauma timing.

The mechanics surrounding MCKs are still yet to be fully understood and have mainly been investigated in terms of trauma timing in BFT cases.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
