What is the preferred bone marrow collection site in adults?

The preferred bone marrow collection site in adults is the anterior or posterior iliac crest. This site is chosen for several important reasons.

Firstly, the iliac crest has a large volume of red marrow, which is essential for obtaining a good sample of hematopoietic tissue. This is crucial for various diagnostic procedures, such as evaluating blood disorders or diseases like leukemia.

Secondly, the iliac crest is easily accessible and allows good visibility and palpation, which simplifies the procedure for healthcare professionals. Unlike other potential sites, the iliac crest provides a relatively safe area to insert the aspiration needle, minimizing the risk of damage to surrounding structures such as blood vessels and nerves.

Finally, using the iliac crest reduces patient discomfort during the procedure as it involves less risk of complications compared to sites like the sternum or femur. Thus, the anterior or posterior iliac crest is considered the ideal site for bone marrow collection in adults, as it offers the best combination of accessibility, safety, and the likelihood of obtaining a sufficient sample for diagnostic evaluation.
