💡 AI Summary & Key Takeaways
– Spinal deformity encompasses adult degenerative scoliosis, flatback syndrome, and sagittal imbalance.
– Modern correction aligns lumbar lordosis with pelvic incidence (PI-LL mismatch correction).
– Restores effortless upright posture and long-term functional mobility.

Adult Degenerative Spinal Deformities
Adult spinal deformity (ASD) arises primarily from asymmetric disc degeneration, facet arthrosis, and progressive loss of lumbar lordosis, resulting in sagittal malalignment, severe pain, and claudication.
Spino-Pelvic Parameter Optimization
Successful reconstructive surgery hinges on restoring individual harmonious pelvic alignment, matching Pelvic Incidence to Lumbar Lordosis ($ ext{PI}- ext{LL} le 10^circ$) to prevent adjacent segment failure and optimize upright posture.
