Bone marrow puncture
A bone marrow puncture is used for diagnosing diseases and their spread in the bone marrow and the hematopoietic system.
A bone marrow biopsy is performed under local anesthesia. To puncture the medullary cavity of a flat bone (e.g. the breastbone or the iliac crest) and to extract tissue, a special hollow needle is employed.
The 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.
