Vertebroplasty of C2 Pathologic Fracture: A Unique Case Report Using a Curved-Needle Technique.

Minimally invasive vertebroplasty has arisen as a viable alternative treatment for pathologic vertebral body fractures. Vertebroplasty is well documented in the thoracic and lumbar spine from the posterolateral approach, but is rarely employed in the cervical spine in consideration of numerous critical neural and vascular structures that must be avoided. Careful technique and usage of imaging is necessary to maneuver crucial structures and minimize risk of complication. In the posterolateral approach, the lesion has to lie in the trajectory of a straight needle, in the lateral aspect of the C2 vertebra. This approach may limit adequate treatment of lesions that are located more medially. We describe a unique case report of successful and safe posterolateral approach treatment of a destructive medial C2 vertebra metastatic lesion using a curved needle.
