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] <45° and lumbar lordosis [LL] apex below L4; Type 2: PI <45° and LL apex above L4; Type 3:45°
