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.

A cylindrically shaped core of bone (or bone biopsy) obtained with a bone marrow trephine is usually examined in the histopathology department of a hospital under a microscope. It shows the pattern and cellularity of the bone marrow as it lay in the bone and is a useful diagnostic tool in certain circumstances such as bone marrow cancer and ...
Detail from The Extraction of the Stone of Madness, a painting by Hieronymus Bosch depicting trepanation (c. 1488–1516). Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb trepan derives from Old French from Medieval Latin trepanum from Greek trúpanon, literally "borer, auger"), [1] [2] is a surgical intervention in which a hole is drilled or ...
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 ...
The distal end of the tibia is the preferred site because it is easy to access and the most reliable. Depending on the procedure, a variety of needles are used for IO. For example, "standard steel hypodermic, butterfly, spinal, trephine, sternal, and standard bone marrow needles are used." Needles that have a short shaft are preferred and safe.
