Case Presentation of Sagittal Balance.

Abstract

Sagittal balance is an important concept in spinal coronal and kyphotic deformity correction. Sagittal alignment/lumbar lordosis is increasingly recognized and discussed in terms of surgical outcomes. Positive sagittal balance can lead to development of iatrogenic kyphosis, flatback syndrome, adjacent level degeneration, and junctional kyphosis. This concept is no longer associated only with deformity. Spine surgeons have learned that sagittal alignment/lumbar lordosis is very important even in 1-level or 2-level interbody fusion procedures, and that it can be attained, maintained, or lost during any procedure, resulting in complications.
