A trephine biopsy should never be performed on the sternum, due to the risk of injury to blood vessels, lungs or the heart. Bone marrow aspiration may also be performed on the tibial (shinbone) site in children up to 2 years of age while spinous process aspiration is frequently done in a lumbar puncture position and on the L3-L4 vertebrae.
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]
A bone biopsy is a procedure in which a small bone sample is removed from the outer layers of bone for examination, unlike a bone marrow biopsy, which involves the innermost part of the bone. The bone biopsy sample retains the architecture of bone when seen using histopathological examination slide.
An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...

[1] A trephine (/ t r ɪ ˈ f aɪ n /; from Greek τρύπανον, trypanon 'instrument for boring') [2] is a surgical instrument with a cylindrical blade. It can be of one of several dimensions and designs depending on what it is meant to be used for.
Vacuum-assisted breast biopsy (VABB) is a more recent version of core needle biopsy using a vacuum technique to assist the collection of the tissue sample. Similarly to core needle biopsy, the needle has a lateral ("from the side") opening and can be rotated, allowing multiple samples to be collected through a single skin incision.
