====== Spondyloptosis ======

Grade V [[Spondylolisthesis]]

Spondyloptosis usually results from high-velocity [[injury]], and many [[patient]]s will also have other associated injuries.

[[Patient]]-Specific [[3D]] Printed [[Model]]s provide added value for initial [[clinical diagnosis]], preoperative surgical and implant [[planning]], and patient and trainee [[education]]. 3D [[spine model]]s are usually designed using [[CT]] [[data]], due to the ability to rapidly image osseous structures with high spatial resolution. Combining CT and [[MRI]] to derive a composite model of bony and neurological [[anatomy]] can potentially provide even more useful information for complex cases. Parthasarathy et al. described 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. They provide a detailed [[workflow]] for creating such models and outline their potential benefit in guiding a [[multidisciplinary]] team approach
