Which bone is specifically assessed for DNA extraction in forensic contexts?

The iliac crest is specifically assessed for DNA extraction in forensic contexts due to its accessibility and the quality of tissue it provides for analysis. The iliac crest, which is the upper margin of the ilium (part of the pelvis), is rich in bone marrow, where hematopoietic cells are found. These cells can yield high-quality DNA, making the iliac crest particularly useful in forensic examinations, especially in cases involving skeletal remains.

Furthermore, the iliac crest is often easier to access during autopsies or post-mortem examinations compared to other bones such as the femur, patella, or sternum. While DNA can be extracted from various bones, the iliac crest is favored in forensic settings for its combination of ease of access and the likelihood of obtaining viable genetic material, particularly in cases of bone fragmentation or degradation.

In contrast, while the femur and sternum can also be used for DNA extraction, they may not consistently provide as reliable a sample as the iliac crest. The patella, being smaller and not as richly vascularized, is even less commonly selected for DNA extraction in forensic contexts.
