Hooks can migrate and potentially cause neurologic impairment and pain long after index surgery, despite the presence of solid spinal fusion. We believe this is partly the result of the surgical technique we used and have since abandoned, and partly the proximal spine settling and fusion mass deformation over time, which we call "proximal junctional scoliosis." We recommend computed tomographic imaging in case of postoperative symptoms and removal of hooks in case of hook migration into the spinal canal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
