Bone-Marrow Biopsy with the Bordier Trephine

Abstract

The experience gained within a 12-month period in 89 bone-marrow biopsies performed by means of the Bordier trephine is reported. The Bordier trephine is larger (inner diameter, 5 mm) than other previously described instruments devised for bone-marrow biopsy. The specimens are taken from the region posterior to the anterior superior iliac spine below the iliac crest, using a special cutting technique by which the bone is completely perforated. The trephine is easy to use and, by the proper technique, invariably yields suitable histological material. From a diagnostic point of view, the large size of the specimen obtained is a great advantage. The only complication encountered in the series was the development of a haematoma in a non-thrombocytopenic patient. EDTA is recommended for the decalcification of the specimens.
