Jamshidi Bone Marrow Biopsy Needles

Jamshidi Bone Marrow Biopsy Needles

The best site for bone marrow biopsy is the posterior superior iliac spine. The biopsy is usually performed using a Jamshidi size 8–11 needle. The first step is to identify the parts of the needle, and then locate the sampling site.

1. The biopsy can be collected from several different sites (anterior or posterosuperior). Mark the preferred sampling site.

2. Administer anaesthesia as described for needle aspiration. When the trephine needle is assembled, it is inserted into the sampling site either directly, or after making a small (0.2cm) incision to facilitate access to the bone. The needle is pushed into the bone by rotating it on its axis.

3. When the desired depth is reached, the stylet is withdrawn and the needle is advanced using the same rotating movement.

4. The depth of the needle is measured using a stylet. A specimen measuring approximately 2cm in length should be collected.

5. When the correct depth has been ascertained, the needle is rotated in the opposite direction to help loosen the specimen. The needle, with the specimen, is then withdrawn using a rotational movement.
