The Minimal Clinically Important Difference (MCID) is crucial to evaluate management outcomes, but different thresholds have been obtained in different works. Part of this variability is due to measurement error and influence of the database, both essential for calculating the MCID. The aim of this study was to introduce the association of the ROC method in the anchor-based MCID calculation for ODI, SRS-22r, and SF-36, to objectively set the threshold for the anchor-based MCID in an adult spine deformity (ASD) population. ⋯ II.

To determine and report the underlying cause of local inflammation causing recurrent neuropathy and multiple operations in a patient with a Barricaid® device. ⋯ Given the constellation of this patient's symptoms, imaging, intraoperative, and pathology findings, previously published reports, and pre-approval data submitted to the FDA, we conclude that the inflammatory response to the PET weave in this patient's Barricaid® device was the ultimate cause of her continued neuropathy despite multiple prior surgical interventions.

To identify risk factors, including FRAX (a tool for assessing osteoporosis) scores, for development of proximal junctional kyphosis (PJK), defined as Type 2 in the Yagi-Boachie classification (bone failure), with vertebral fracture (VF) after surgery for symptomatic adult spinal deformity. ⋯ Preoperative assessment of severity of osteoporosis using FRAX provides an accurate estimate of risk of postoperative PJK with VF after surgery for adult spinal deformity.
