It is critical that the operator has access to high-quality imaging guidance so that key bony landmarks, such as the spinous process, pedicle, vertebral endplates, and posterior

Histologic evaluation of VP or KP treated vertebrae has revealed cement infiltration of vascular spaces throughout the
vertebral body and venous system.
Any painful lesion involving the

The surgery restored a mean of 35% of the
vertebral body height that had been lost with fracture.
The patient underwent decompression of the right vertebral artery by removal of osteophytic ridging associated with the C1

Daffner et al (9) described 5 radiographic signs that are suggestive of instability: displacement of a

vertebral body, and an increased interpediculate width of 2 mm.
No significant restoration of
vertebral body height was observed.
Currently vertebroplasty is used to treat symptomatic osteoporotic compression fractures, steroid-induced osteoporotic compression fractures,
vertebral body hemangiomas, and metastatic disease of the spine.
C Vertebral Augmentation System is used by physicians to create channels within the

A corpectomy is a surgical procedure that involves removing part of the

5) Involvement of a disc in conjunction with a
