Simulation Training in Spine Surgery

Wang Z, Shen J

Simulated surgery is part of a growing paradigm shift in surgical education as a whole. Various modalities from cadaver models to virtual reality have been developed and studied within the context of surgical education.

A Revolution on the Frontlines of Deliberate Surgical Training in Orthopedics

Brambert J

Innovators in surgical training and education, SurgiSTUD (STUD is an acronym for Surgical Training Utility Device), announced it's launching a new orthopedic subdivision in their STUD catalog. These STUDs are surgical training models with superior biomechanical fidelity, customizability, and cost-savings over existing cadaveric and synthetic training options.

The Barrow Biomimetic Spine: Fluoroscopic analysis of a synthetic spine model of variable 3D-printed materials and print parameters.

Bohl M, Mooney M, Repp G, Nakaji P, Chang S, Turner J, Kakarla U.

The Barrow Biomimetic Spine project aims to develop a 3-dimensional (3D) printed, synthetic spine model that will one day replace cadaveric tissue in spine biomechanical research. A crucial component to any biomimetic spine model is that it performs similarly to cadaveric tissue on standard diagnostic imaging modalities.

The Barrow Biomimetic Spine: Comparative testing of a 3D-Printed L4-L5 Schwab grade 2 osteotomy model to a cadaveric model.

Bohl M, Mooney M, Repp G, Cavallo C, Nakaji P, Chang S, Turner J, Kakarla U.

The purpose of this study was to evaluate the biomechanical performance of an L4-L5 3D-printed synthetic spine model in a lordotic correction test after Schwab grade 2 osteotomies as compared to human cadaveric spines that have undergone the same osteotomies and lordotic correction.

Disc geometry is an accurate predictor of lordotic correction in the thoracolumbar spine following Schwab grade-2 osteotomy: A cadaveric study and biomechanical analysis of disc space changes following lordotic correction.

Bohl M, Hlubek R, Mooney M, Chapple K, Preul M, Chang S, Turner J, Kakarla U. 

Posterior column osteotomy (PCO) is a powerful technique for correcting lordosis, but the surgical literature lacks objective evidence on preoperative predictors of achievable lordotic correction following PCO.

Three-dimensional printed models for lateral skull base surgical training: Anatomy and simulation of the transtemporal approaches.

Mooney M, Cavallo C, Zhou J, Bohl M, Belykh E, Ghandi S, McBryan S, Stevens S, Lawton M, Almefty K, Nakaji P.

To develop and evaluate a 3D-printed model that accurately represents the anatomic relationships, surgical corridor, and surgical working angles achieved with increasingly aggressive temporal bone resection in lateral skull base approaches.

Evaluation of a novel surgical skills training course: are cadavers still the gold standard for surgical skills training?

Bohl MA, McBryan S, Spear C, Pais Hs D, Preul MC, Wilhelmi B, Yeskel A, Turner JD, Kakarla UK, Nakaji P.

The purpose of this study was to describe a surgical skills course comprising entirely synthetic training models developed by resident and attending neurosurgeons and to evaluate their perceptions of the overall usefulness of this course and its usefulness compared with cadaveric courses.
