Three-dimensional rotational X-ray navigation for needle guidance in percutaneous vertebroplasty: an accuracy study.


STUDY DESIGN The position of a needle tip displayed on a navigation system after transpedicular introduction into a vertebral body is compared with the real position of the needle tip when using a direct navigation coupling between a three-dimensional rotational X-ray (3DRX) system and a navigation system. OBJECTIVES To assess whether the needle tip… (More)
