The Radner Needle a Bone‐Marrow Biopsy Device

Experience gained in 2000 bone-marrow biopsies performed by means of the Radner needle is reported. The site for the biopsies was in all cases the posterior superior iliac crest. The technique is routinely used in patients with haematological disorders, such as leukaemia and malignant lymphomata, or with solid tumours. Technically, the Radner needle is easy and simple to use, and in nearly all cases it has yielded ideal specimens for histological examination. The only complications encountered were slight pain and a small haematoma at the biopsy site in a few cases. The method is recommended for routine use simultaneously with bone-marrow aspiration.
