Procedure

Most common site for bone marrow biopsy is iliac wing.

CT guidance commonly used.
• Prone patient with posterior approach
• Advance needle along length of the iliac wing.
• For right iliac wing biopsy, operator stands on patient's left and skin entry site is midline with lateral trajectory
• Seat needle just beyond cortex. Occasionally, helpful to have mallet to assist with seating the needle beyond the cortex
• Remove inner stylet. Aspirate with large volume syringe (20 - 30 mL)
• Following aspiration, advance biopsy device without inner stylet into iliac wing 2-3 cm,
• Can be helpful to gently rock biopsy device to help capture specimen. Many devices have additional tools to assist with specimen capture

Following successful aspirate and bone biopsy,
• Hemostasis with compression
• Apply sterile dressing
• Option to take final pictures confirming no immediate post operative complication
