In General, sagittal spinal imbalance is divided into dynamic and static type. Static sagittal imbalance is due to iatrogenic, post-traumatic causes and the major contributory factor of dynamic sagittal imbalance is degenerative change such as lumbar degenerative kyphosis. The operative technique and method of correction for static sagittal imbalance is established somewhat and dynamic sagittal imbalance has different pathophysiology from the static one. So the operative method for correction of dynamic sagittal imbalance should be different from the static one. The degenerative change and segmental instability of lumbar spine in dynamic sagittal imbalance and accordingly, loss of lumbar lordosis and sagittal imbalance causes lumbar kyphosis and forward bending of the body. But there are a few studies about dynamic sagittal imbalance and there is controversy about operative method for correction of dynamic sagittal imbalance.
