Abstract

This report details a trial demonstrating the viability of a blunt-tipped curved needle for use as a cement injection device for vertebral body augmentation. Between January and September 2007, 17 consecutive patients (eight men and nine women; average age, 76 years; age range, 52-97 years) underwent vertebral body augmentation with a blunt-tipped curved nitinol injection needle via a single pedicle to treat pain due to acute vertebral body compression fractures. All patients were successfully treated without complication. The results of the trial demonstrate that a curved blunt-tipped nitinol needle is a viable alternative to a rigid injection cannula when performing vertebral body augmentation with cement.
