Bone marrow biopsy needle method

Bone marrow aspirate and bone marrow biopsy are routine operations in the Department of Hematology. Patients with suspected hematological diseases need bone marrow aspirate and bone marrow biopsy to further confirm the diagnosis. Bone marrow biopsy and bone marrow aspiration are usually performed simultaneously and are performed under local anesthesia.

The sternum and ilium can be selected for bone marrow biopsy, but the sternum is usually not selected for bone marrow biopsy, only the ilium is selected, because if a bone marrow biopsy is performed at the position of the sternum, it may lead to the perforation of the sternum, which may cause unexpected situations such as mediastinal emphysema.

Bone marrow biopsy is to take a bone marrow biopsy needle, then enter the bone marrow cavity, and take about 1 cm of bone marrow tissue for examination.
