Pre-vertebroplasty work-up
The patient and caregivers were informed of the risks and benefits of
the procedure, as well as the paucity of evidence for the procedure in
the pediatric setting, and written informed consent was obtained. Since
all patients had spine, chest, or abdominal computed-tomography (CT) or
magnetic resonance imaging (MRI) performed for other reasons less than 3
months prior to vertebroplasty, no further imaging was necessary prior
to the intervention. Platelet count of >50,000/mcL and INR
< 1.5 were required to proceed. Any supplementary laboratory
workup deemed necessary by the anesthesiologist was completed.
