A unilateral vertebroplasty approach using a curved injection cannula for directed, site-specific vertebral body filling.

摘要

The present report describes the use of a curved, coaxial infusion cannula that can be applied to facilitate targeted multifocal vertebral body cement injection during vertebroplasty from a single access site. Two representative cases are presented that illustrate the ability of targeted cement deposition and flexible site selection with this technique.
