Mixed reality simulation of rasping procedure in artificial cervical disc replacement (ACDR) surgery

Background:A host of factors have contributed to the increasing use of simulation in neurosurgical resident education. Although the number of simulation-related publications has increased exponentially over the past two decades, no studies have specifically examined the role of simulation in resident education in spinal neurosurgery.Methods:We performed a structured search of several databases to identify articles detailing the use of simulation in spinal neurosurgery education in an attempt to catalogue potential applications for its use.Results:A brief history of simulation in medicine is given, followed by current trends of spinal simulation utilization in residency programs. General themes from the literature are identified that are integral for implementing simulation into neurosurgical residency curriculum. Finally, various applications are reported.Conclusion:The use of simulation in spinal neurosurgery education is not as ubiquitous in comparison to other neurosurgical subspecialties, but many promising methods of simulation are available for augmenting resident education.

“…The system consists of a physical and virtual component, in which the trainees perceive both the physical environment around them and the virtual elements coexisting in the same space [10,20,29,30]. Thus, this simulator provides hints for real-world training, integrating patient-specific characteristics and virtual system [21,22].…”

Advances in imaging and computer technology have led to the development of different simulation models to complement traditional surgical training. Sophisticated virtual reality (VR) simulators with haptic feedback and impressive imaging technology have provided novel options for training in neurosurgery. Breakthrough training simulation using 3D printing technology holds promise for future simulation practice, proving high-fidelity patient-specific models to complement residency surgical learning.

“…To satisfactorily reproduce the challenges of the surgical scenario that is intended to be simulated, surgical simulators (virtual reality, mixed, or synthetic) must properly address 3 specific challenges of simulation: graphics/volume rendering, tissue deformation, and haptic feedback. 15,22,34,36,55,65 Regarding the first of these points, a common challenge for both synthetic and virtual-reality simulators is to faithfully reproduce the morphometric characteristics and the dimensional proportions among the anatomical structures under simulation. The most common strategy in synthetic simulation is to use 3D printers loaded with DICOM images to produce synthetic models with patient-specific anatomical characteristics.…”

“…4,19,35,39,61,64 For instance, in the laparoscopic literature, the surgical field that has most contributed to advancing the field of surgical simulation (as well as the specialty that has earlier incorporated its benefits into its educational processes), the vast majority of the available training programs still strongly rely on synthetic simulators. 10,14,16,22,24,26,59 Several simulators of neurosurgical procedures have already been developed and are currently being used as adjuvant tools for enhancing the quality of neurosurgical training. A nonexhaustive list of synthetic simulators include an intracranial endoscopic simulator, 19 a model for minimally invasive spine surgery, 61 a simulator for paranasal and skull base endonasal endoscopic surgery, 38 a model of foramen ovale puncture, 4 a simulator of open skull base approaches, 64 and a general microsurgical simulator for vascular intracranial procedures.…”

Object Simulation has become an important tool in neurosurgical education as part of the complex process of improving residents' technical expertise while preserving patient safety. Although different simulators have already been designed for a variety of neurosurgical procedures, spine simulators are still in their infancy and, at present, there is no available simulator for lumbar spine pathologies in pediatric neurosurgery. In this paper the authors describe the peculiarities and challenges involved in developing a synthetic simulator for pediatric lumbar spine pathologies, including tethered spinal cord syndrome and open neural tube defects. Methods The Department of Neurosurgery of the University of Illinois at Peoria, in a joint program with the Mechanical Engineering Department of Bradley University, designed and developed a general synthetic model for simulating pediatric neurosurgical interventions on the lumbar spine. The model was designed to be composed of several sequential layers, so that each layer might closely mimic the tensile properties of the natural tissues under simulation. Additionally, a system for pressure monitoring was developed to enable precise measurements of the degree of manipulation of the spinal cord. Results The designed prototype successfully simulated several scenarios commonly found in pediatric neurosurgery, such as tethered spinal cord, retethered spinal cord, and fatty terminal filum, as well as meningocele, myelomeningocele, and lipomyelomeningocele. Additionally, the formulated grading system was able to account for several variables involved in the qualitative evaluation of the technical performance during the training sessions and, in association with an expert qualitative analysis of the recorded sessions, proved to be a useful feedback tool for the trainees. Conclusions Designing and building a synthetic simulator for pediatric lumbar spine pathologies poses a wide variety of unique challenges. According to the authors' experience, a modular system composed of separable layers that can be independently replaced significantly enhances the applicability of such a model, enabling its individualization to distinctive but interrelated pathologies. Moreover, the design of a system for pressure monitoring (as well as a general score that may be able to account for the overall technical quality of the trainee's performance) may further enhance the educational applications of a simulator of this kind so that it can be further incorporated into the neurosurgical residency curriculum for training and evaluation purposes.
