Sagittal balance is an integral part of human posture — and a central principle of modern spine surgery.
This video aims to break down concept in a structured way:
🔹 What sagittal balance is and why it matters
🔹 The five key parameters that define it
🔹 The compensatory chain when balance is lost (pelvis → hips → knees → spine)
🔹 The Roussouly classification and how each type shapes natural spinal alignment
🔹 The Schwab sagittal modifiers and the alignment targets used in adult deformity surgery
🔹 How degenerative changes progress into fixed sagittal imbalance
🔹 Surgical correction principles: restoring lumbar lordosis, reducing pelvic tilt, and rebalancing the entire spinal chain
🔹 Why every spine must be corrected according to its own morphology
All of the models presented, as well as the video itself are available on the "3D Atlas of Neurological Surgery" platform.
