Less invasive anterior column reconstruction in thoracolumbar fractures

Abstract

Posterior short-segment pedicle screw constructs are commonly used for reduction and fixation of traumatic thoracolumbar spine fractures. Although this technique is usually simple and effective, complications such as loss of fixation or recurrence of deformity are common because of the insufficiency of the damaged anterior column. Anterior approaches to address this deficiency are associated with high morbidity and complications. We have developed a technique to reduce and support the fractured anterior column through a transpedic-ular approach. Balloon-assisted-endplate-reduction (BAER) followed by vertebroplasty (VTP) with calcium phosphate cement in combination with short segment pedicle screw construct seem to be a safe and effective technique to reconstruct the anterior column in a less invasive manner. In this article, the rationale behind this technique, experimental studies, and the first clinical results are discussed.
