Kitchen elbow sign predicts surgical outcomes in adults with spinal deformity: a retrospective cohort study

Abstract Kitchen elbow sign (KE-Sign) is a skin abnormality on the extensor side of the elbow and forearm that is often observed in patients with adult spinal deformity (ASD). The significance of KE-Sign in surgical cases was investigated. Overall, 114 patients with ASD treated with long spinal fusi...
