Biopsy needle and bone penetration

 

For peripheral bone biopsy Subperiostal or cortical lesions without ossification : they are directly punctured with a 14-gauge needle.

  • In cases with mild ossification or small cortex surrounding the lesion we use a 14-gauge Ostycut bone biopsy needle and penetration is performed with a surgical hammer (Ostycut, Angiomed / Bard, Karlsruhe, Germany).
  • In cases of mild condensation, and for primary tumors or lymphoma we use a 8-gauge trephine needle (Laredo type).
  • In cases of dense ossification, or of dense cortical bone surrounding the lesion, drilling was necessary. In these cases we use a 2-mm diameter hand drill or a 14-gauge Bonopty Penetration set (Radi Medical Systems Uppsala, Sweden).

For vertebral body biopsy

  • We use an Ostycut bone biopsy needle and penetration is carried out with a surgical hammer (Ostycut, Angiomed / Bard Karlsruhe, Germany).
  • We use a 14 gauge needle in cervical thoracic and lombar level. In cases of mild condensation, and for primary tumors or lymphoma we use a 8-gauge trephine needle (Laredo type).
  • In cases of dense ossification, surrounding the lesion, drilling is necessary. In these cases we use a 2-mm diameter hand drill or a 14-gauge Bonopty Penetration set (Radi Medical Systems, Uppsala, Sweden).

For soft tissue biopsies True cut 14 to 16-gauge needles are used (Temno allegiance)
