Combining CT and MRI to derive a composite model of bony and neurological anatomy can potentially provide even more useful information for complex cases. We describe such a case involving an adolescent with a grade V spondylolisthesis in which a composite model was manufactured for preoperative and intraoperative evaluation and guidance. We provide a detailed workflow for creating such models and outline their potential benefit in guiding a multidisciplinary team approach.<\/jats:p>","DOI":"10.1136\/bcr-2020-239192","type":"journal-article","created":{"date-parts":[[2021,3,1]],"date-time":"2021-03-01T11:00:40Z","timestamp":1614596440000},"page":"e239192","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Customised
