The Technique for Performing Posterior Vertebral Column Resection with En-Bloc Fixation/Reduction in Adult Spine Deformity Surgery.

Medial rib resection in the thoracic spine allows easy access to the lateral vertebral column.En-bloc fixation-reduction minimizes fixation failure above and below the level of resection and provides a rigid foundation during the correction maneuver.Ensure that the anterior column is disconnected all the way across in order to avoid excessive shortening of the spinal cord and the potential neurologic sequelae.Complete resection of the posterior cortex and scar tissue anterior to the dural sac is required prior to the correction maneuver.Ensure an adequate number of fixation points above and below the resection level.
