Article: Does baseline thoracolumbar shape influence patterns of cervical decompensation following surgical adult spinal deformity correction?

Authors (excerpt): Max R Fisher, Alyssa M Bartlett, Renaud Lafage, Virginie Lafage, Bassel Diebo

Overview: OBJECTIVE: Adult spinal deformity (ASD) surgery is complex and may lead to postoperative cervical deformity (CD) and/or proximal junctional kyphosis. The Roussouly classification describes four types of baseline thoracolumbar (TL) morphology, which differentially influence surgical outcomes. However, their role in predicting CD remains underexplored. This study aimed to stratify TL-ASD patients by Roussouly types and examine postoperative CD development patterns. METHODS: The authors included operative ASD patients with no prior fusion and complete radiographic data at baseline, 6 weeks, 1 year, and 2 years. Patients were categorized into Roussouly types 1-4 using baseline pelvic incidence and lumbar lordosis apex. CD was assessed using a point system: cervical sagittal vertical axis (cSVA) of 40-80 mm = 1 point, T1 slope minus cervical lordosis (TSCL) of 15°-20° = 1 point, cSVA > 80 mm = 2 points, and TSCL > 20° = 2 points. CD was…
