Evaluate surgical treatment outcomes and identify best practice guidelines for complex adult spinal deformity (ASD) patients, including radiographic and clinical outcomes, surgical and postoperative complications, risk factors for and revision surgery rates, and the role of standard work to improve patient outcomes and reduce surgical and postoperative complications.
Specific Aims: • Evaluate surgical treatment outcomes and identify best practice guidelines for complex adult spinal deformity (ASD) patients, including radiographic and clinical outcomes, surgical and postoperative complications, risk factors for and revision surgery rates, and the role of standard work to improve patient outcomes and reduce surgical and postoperative complications. a. Complex ASD patients will be defined based upon clinical, radiographic and/or procedural criteria identified in an analysis of the existing ISSG ASD database: i. Magnitude of coronal and/or sagittal spinal de…
Criteria: Inclusion Criteria: 1. Diagnosis of adult congenital, degenerative, idiopathic or iatrogenic spinal deformity 2. Full body EOS radiographic assessment (sagittal and coronal visualization from skull to foot) 3. Complex patients are defined as and meeting any one of the subsequent criteria: 1. Radiographic criteria: * PI-LL ≥ 25 degrees * TPA ≥ 30 degrees * SVA\>15cm * Thoracic scoliosis ≥ 70 degrees * Thoracolumbar/lumbar scoliosis ≥ 50 degrees * Global coronal malalignment \>7cm 2. Procedural criteria: * Posterior spinal fusion \>…
Surgical interventions will be patient specified by treating surgeon.
