Alignment Factors Associated with the Need for Revision Extension Surgery to the Sacrum After Previous Lumbar Spinal Fusion
Frailty, longer constructs, and inadequate caudal lordosis independently predicted sacral extension during revision, while optimal L1PA alignment was protective. The most common indications were distal junctional degeneration, pseudoarthrosis, foraminal stenosis, and spondylolisthesis. These findings may aid preoperative risk stratification and surgical planning.
