Utilizing the Fracture Risk Assessment Tool (FRAX) to Assess Risk of Proximal Junctional Kyphosis in Adult Spinal Deformity Surgery

BACKGROUND CONTEXT: Proximal junctional kyphosis (PJK) is a difficult complication in adult spinal deformity. While several risk factors for PJK have been identified, there is concern that osteoporotic bone can contribute to the development of PJK. To date, there is no cumulative risk calculation that correlates with PJK development. The Fracture Risk Assessment Tool (FRAX) is a well-validated risk model that predicts the 10-year probability of significant osteoporotic fracture. Because the FRAX tool is a comprehensive osteoporotic fracture risk assessment, we believe that it will be a useful surrogate in predicting the development of PJK after ASD surgery.
