Posterior Minimally Invasive Transpedicular Approach for Giant Calcified Thoracic Disc Herniation.

Study Design: Retrospective case series.

Objective: Posterior surgery for thoracic disc herniation was associated with increased morbidity and mortality and new minimally invasive approaches have been recommended for soft disc herniation but not for calcified central disc. The objective of this study is to describe a posterolateral microscopic transpedicular approach for central thoracic disc herniation.
