Arrow® OnControl® Powered Bone Marrow Biopsy Procedure

Ensures Better Overall Patient Experience

Generally, you will be asked to lie on your abdomen or on your side and you will be draped so only your lower back is exposed. Your health care provider will palpate your lower back to find the top ridge of your pelvis. Once the health care provider has found the right location, the area will be cleaned and then numbed.

The Arrow® OnControl® Powered Bone Marrow Biopsy System works with a powered driver and a specially designed needle. During the procedure, you will hear a sound and feel the vibration of the needle.

With bone marrow procedures, adverse events are rare. Bruising, bleeding and infections of the insertion site are the most frequently reported incidents.


An incision will be made and a needle inserted through the skin. Once the needle touches the bone, you will hear the power driver start and you may feel some vibration. Typically, within several seconds, your health care provider will stop and take a specimen of liquid marrow with a syringe.


After the aspirate has been collected, the powered driver is restarted and, in a matter of seconds, your health care provider will capture a specimen of the solid marrow.

After removal of the needle, a health care provider will put pressure on the incision site until the bleeding stops and a bandage will be placed on the site. Discuss with your health care provider how best to manage post procedure discomfort and the level of activity you should resume following the procedure. Ensure you follow all instructions regarding driving or resuming full activity.

The Arrow® OnControl® Powered Bone Marrow Biopsy System and Powered Bone Lesion Biopsy System should not be used by clinicians unfamiliar with the complications, limitations, indications, and contraindications of bone marrow aspiration and biopsy.
