Evolution of Sagittal Imbalance Following Corrective Surgery for Sagittal Plane Deformity.

Background: Sagittal balance in adult spinal deformity is a major predictor of quality of life. A temporary loss of paraspinal muscle force and somatic pain following spine surgery may limit a patient's ability to maintain posture.

Objective: To assess the evolution of sagittal balance and clinical outcomes during recovery from adult spinal deformity surgery.
