Jamshidi needle

The Jamshidi needle is a trephine needle for performing bone marrow biopsy, whereby a cylindrical sample of tissue, a core biopsy specimen, is obtained. It is a cylindrical needle with a tapered cutting tip.^[1] The tapered end reduces the potential of crush artifact.^[2] It is the most commonly used needle for performing bone marrow biopsies.^[3] The device is named for its inventor Khosrow Jamshidi who is an Iranian physician.^[4]

The Jamshidi interosseous needle has also been successfully used in pediatric patients, where a conventional intravenous line could not be established.
