Why is a Bone Marrow Done?

Examination of the bone marrow is the most valuable diagnostic test to evaluate hematologic disorders. Bone marrow aspiration and biopsy also is used to stage lymphoproliferative disorders and for prognostic purposes in chronic lymphoproliferative disorders such as chronic lymphatic leukemia.

Bone marrow aspiration and biopsy also is useful in the diagnostic workup of fever of unknown origin (FUO). It may reveal infections, such as tuberculosis, Mycobacterium avium-intracellulare (MAI) infections, histoplasmosis, leishmaniasis, and other disseminated fungal infections. It may be useful in establishing the diagnosis of storage diseases, such as Niemann-Pick disease and Gaucher disease. Finally, it can be a valuable tool in diagnosing metastatic nonhemopoietic malignancies that have spread to the bone marrow when all other imaging and diagnostic modalities have failed or when a leucoerythroblastic peripheral blood picture is present.

Bone Marrow Biopsy Technique

Proper technique is required to obtain an adequate sample and a suitable specimen for processing. The pathology request should contain all the pertinent clinical information and laboratory data. Obtaining informed consent and providing information regarding the procedure will minimize any apprehension that the patient may have, as will talking to the patient during each step of the bone marrow aspiration and biopsy.

Bone Marrow Biopsy Complications

Complications from a bone marrow aspiration and biopsy include infection and bleeding. With proper sterile atraumatic technique these complications are rare. Absolute contraindications to performing the procedure include hemophilia or related coagulation disorders and infection involving the biopsy area. Thrombocytopenia is not a contraindication, but take care to avoid trauma that is more significant than usual. Another very rare complication from the procedure is cardiac injury after a sternal bone marrow aspiration, which can be prevented with good technique and by using the guard provided with the bone marrow aspiration needle to avoid deep penetration.

Biopsies never should be obtained from the sternum; only aspiration is performed in that area. Iliac bone perforation and hemorrhage may occur because of improper technique and patient positioning.

Chronic pain at the site of the bone marrow aspiration and biopsy is very rare.
