Needle biopsy of bone marrow and osteo-medullar biopsy: indications and technique

The needle biopsy of bone marrow is a technique which helps to get a sample of medullar juice mixed with some blood. It is then possible to quickly quantify and qualify the comparment of blood cells production. It is indicated in the exploration of most of the severe blood abnormalities such as cytopenias and hypercytoses. The medullar biopsy often completes the needle biopsy. It precises topographical links between cells groups and it studies the framework of reticuline; it is essential in the event of a hypocellular puncture and it is indicated in the event of a suspicion of myeloproliferative syndrome, myelodysplasia syndrome, myelofibrosis, medullar aplasia and in an extension overview of a malignant lymphoma or carcinomas. The result is thus more belated because the sampling treatment needs a few days.
