Spinal Implant Density and Postoperative Lumbar Lordosis as Predictors for the Development of Proximal Junctional Kyphosis in Adult Spinal Deformity

Abstract Objective To evaluate spinal implant density and proximal junctional kyphosis (PJK) in adult spinal deformity (ASD). Methods Consecutive ASD patients receiving > 5 level fusions were retrospectively analyzed between 2007 and 2010. Inclusion criteria: ASD, elective fusions, minimum 2-year...
