Posterior spinal fusion (PSF) is an effective and safe treatment for various spinal deformities in the pediatric population, including Scheuermann’s Kyphosis. Several studies have evaluated the variations in pedicle anatomy, parameters to detect pedicle breach, and need for postoperative computerized tomography scan (CT scan). The purpose of this case study is to present an example of PSF in a relatively large male patient with Scheuermann’s Kyphosis. The surgery was uneventful and relatively long pedicle screws were used. Postoperative X Rays showed pedicle screws crossing the midline at several levels. Further work up with CT did not demonstrate any medial breaches. In conclusion, long pedicle screws are not necessarily malpositioned if they cross the midline.
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.
