Adult spinal deformity (ASD) encompasses a wide spectrum of spinal malalignment patterns, ranging from simple biplanar and segmental deformities to complex three-dimensional global deformities characterized by significant disruptions in coronal and sagittal alignment^1,2. Surgical management for ASD offers both superior radiographic and HRQOL outcomes compared with nonoperative care^3,4,5. However, these procedures are often complex and may be associated with high rates of perioperative complications^6,7,8,9.

Although a two-stage surgical strategy has been proposed to reduce complications in adult spinal deformity (ASD) surgeries^10,11,12planning for the second-stage procedure is traditionally based on the preoperative parameters established before the first surgery. Most related studies also use these initial preoperative parameters as the basis for research^13,14. However, due to varying degrees of improvement after the first surgery, the original plan for the second procedure may need modification. Based on previous research findings¹⁵we hypothesize that...(More)
