Hypothesis: Reciprocal changes in the upper cervical spine correlate with adult TL deformity modifiers.
Design: This was a retrospective review.
Introduction: The upper cervical spine has remarkable adaptability to wide ranges of thoracolumbar (TL) deformity.
Methods: Patients >18 years with adult spinal deformity (ASD) and complete radiographic data at baseline (BL) and 1 year were identified. Patients were grouped into component types of the Roussouly classification system (Type 1: Pelvic incidence [PI]
Results: A total of 343 ASD patients were analyzed. When grouped by BL Schwab and Roussouly, Group
Conclusions: Our study suggests that upper cervical alignment remains relatively stable through most broad variations of adult TL deformity. Changes in SVA correlated most with upper cervical changes.
