Bone marrow puncture
A bone marrow puncture is used for diagnosing diseases and their spread in the bone marrow and the hematopoietic system.
After local anesthesia, the medullary cavity of a flat bone (e.g. the breastbone or the iliac crest) is punctured with a special hollow needle to extract tissue for of a bone biopsy or bone marrow biopsy.
The extracted bone marrow sample/biopsy is used to determine whether the bone marrow is infiltrated by Hodgkin lymphoma, that is, whether stage IV Hodgkin lymphoma is present.
