Abstract
Ignoring the sagittal profile in primary spinal fusion surgery is a common reason for revision surgery. Therefore, it is important that in cases of spinal revision surgery the sagittal alignment is realized. The physiological alignment of the instrumented spine should also indirectly influence the profile of the non-stabilized spine cranial and caudal to the fusion. Patients with normal C7 plumb-line and a physiological sacral inclination have a lower incidence of adjacent segment degeneration. Sagittal imbalance after revision surgery is a risk factor for recurrent pseudarthrosis. In cases of pseudarthrosis a combined approach may be more effective in realizing sagittal balance und enhancing rates of fusion.
