Note: Please see pages ii , iii for a list of anatomic terms/abbreviations used throughout this book.

A parallel technique between the table of the ilium under fluoroscopic guidance avoids breach and allows for aspiration from multiple sites to maximize yield.

Trajectory View ( Fig. 36A.1 )

  • The entry point for the bone marrow aspirate trocar is not more than 10 cm cephalad to the posterior superior iliac spine .

  • The image intensifier is obliqued approximately 40 degrees contralaterally.

  • The C-arm is then tilted cranially approximately 35 degrees.

  • The ideal “setup view” delineates the medial and lateral tables of the posterior iliac crest.

  • In the trajectory view, the needle should be placed parallel to the fluoroscopic beam.

  • Once the trocar penetrates the cortical bone, the sharp tip of the stylet can be exchanged with a blunt tip.

  • Other multiplanar imaging views should also be utilized for needle advancement.

  • The needle is advanced 4 to 8 cm between the medial and lateral tables of the ilium.
