“…Computer simulation is very well documented and has been used successfully in the military and in the aviation field. Its use and interest as an educational tool in the medical field is rapidly growing; [16][17][18][19][20] some universities even have dedicated departments for the virtual training of future medical practitioners. Accordingly, the number of orthopedic surgeons using navigation techniques is also increasing.…”

Background:The training of orthopedic residents in adequate pedicle screw placement is very important. We sought to investigate orthopedic residents' perspectives on the use of computer-assisted surgery (CAS) in a training trial. Methods:Orthopedic residents were randomly assigned to independently place a screw using the free-hand technique and the CAS technique on 1 of 3 cadavers (Cobb angles 5º, 15º and 67º) at randomly selected thoracolumbar vertebral levels. All residents were blinded to their colleagues' pedicle screw placements and were asked to complete a short questionnaire at the end of the session to evaluate their experience with CAS. We obtained CT images for each cadaver to assess pedicle screw placement accuracy and classified placement as A) screw completely in pedicle, B) screw < 2 mm outside pedicle, C) screw 2-4 mm outside pedicle, or D) screw > 4 mm outside pedicle.Results: Twenty-four orthopedic residents participated in this trial study. In total, 65% preferred using the free-hand technique in an educational setting even though most (60%) said that CAS is safer. The main reason for free-hand technique preference was the difficult technical aspects encountered with CAS. In addition, accuracy of pedicle screw placement in this trial showed that 5 screws were classified as A or B (safe zone) and 19 as grade C or D (unsafe zone) using the free-hand technique compared with 15 and 9, respectively, using CAS (p = 0.008). Conclusion:Orthopedic residents perceived CAS as safe and demonstrated improved accuracy in pedicle screw placement in a single setting. However, the residents preferred the free-hand technique in an educational stetting owing to the difficult technical aspects of CAS.Contexte : Il est très important d'apprendre aux médecins résidents en chirurgie orthopédique comment positionner adéquatement une vis pédiculaire. Notre objectif était d'obtenir l'opinion des médecins résidents sur le recours à la chirurgie assistée par ordinateur (CAO) dans un essai sur la formation. Méthodes :Des médecins résidents en chirurgie orthopédique répartis aléatoire-ment ont placé indépendamment une vis à l'aide d'une technique à main libre basée sur les repères topographiques et la palpation, et de la CAO dans 1 de 3 cadavres (angles de Cobb de 5°, 15° et 67°) dans une vertèbre dorsolombaire sélectionnée aléatoirement. Aucun des médecins résidents n'a pu observer le positionnement de la vis de ses collègues, et les participants ont rempli un court questionnaire à la fin de la séance pour évaluer leur expérience de la CAO. Nous avons obtenu un tomodensitogramme pour chaque cadavre afin d'évaluer la précision du positionnement de la vis pédiculaire, classée selon 4 catégories : A) vis entièrement dans le pédicule, B) vis < 2 mm hors du pédicule, C) vis de 2-4 mm hors du pédicule, ou D) vis > 4 mm hors du pédicule.Résultats : Vingt-quatre médecins résidents en chirurgie orthopédique ont participé à l'étude clinique. Au total, 65 % d'entre eux ont préféré utiliser la technique à main libre dans un contexte d...

“…Furthermore, patient-specific models have been designed in VR simulation to answer the "ceiling effect associated with the fixed nature of the anatomy model" described by Essani et al (35). Patient-specific models have been designed on various medical fields such as vascular, craniofacial, rectal surgery, neurosurgery, or percutaneous interventions (36). Finally, VR simulators have also been developed and validated in the field of robotic surgery (37).…”

Background and Aims: The mastery of manual skills that are indispensable for the performance of surgical tasks is a competence specific to surgery. one way of facilitating this acquisition is to move the training out of the operating room and all of its restrictions. Surgical training out of the operating room, also called simulation, has spread widely in the past decade, especially in laparoscopic and endoscopic surgery. Material and Methods: This review assesses the role of virtual reality (Vr) simulators in laparoscopic surgery and their actual impact on technical skills.Results and Conclusions: There is a wealth of simulators, ranging from low-to highfidelity simulators incorporating haptic feedback. They comprise basic tasks, procedural modules, and full procedures. Virtual reality simulators have shown acceptable fidelity and validity evidence. moreover, training out of the operating room on virtual reality simulators has demonstrated its positive impact on basic skills during real laparoscopic procedures in patients. The benefit of virtual reality over simple video trainers remains unclear for teaching basic skills. however, virtual reality simulators provide automatic feedback that permitted to design structured competency-based curricula and allow deliberate practice. finally, advanced procedures and patient-specific models have been designed on virtual reality simulators, and further investigations are still awaited to appraise their educational value.

“…A recent state of the art on researches into patientspecific virtual reality medical simulation is presented in [16]. The primary potentials of those simulators are also training and planning rehearsal but few of them have metrics, face an content validation and none of them use ultrasound guidance and simulate respiration behavior.…”

We present here a new simulator for visceral needle puncture training in interventional radiology. This is the result of a close collaboration between different universities, involving computer scientists, clinicians and clinical engineers. Together, we address the need of segmentation, physically-based modelling, haptics rendering, pseudo-ultrasound generation and the conception of a mannequin required to build an efficient real-time simulator. Clinical face and content validations have also been performed and show the reliability and effectiveness of this framework.
