Are Higher Global Alignment and Proportion Scores Associated With Increased Risks of Mechanical Complications after Adult Spinal Deformity Surgery? An External Validation.

CONCLUSIONS: Based on the findings of this external validation study, we found that alignment targets based on the GAP score alone were not associated with increased risks of mechanical complications and mechanical revisions in patients with complex adult spinal disorders. Parameters not included in the original GAP score needed to be considered to reduce the likelihood of mechanical complications.
LEVEL OF EVIDENCE: Level III, diagnostic study.
