Conclusions Anatomical changes due to fractures provide an efficient
method of identification of skeletal and decomposed human remains when comparison elements are available.
In our community, it is difficult to obtain medical, hospital and dental records.
Identification by DNA profiling is the most frequently used identification method in our Service.
