Toronto, Ontario, Canada —November 8, 2023 – Dans le cadre d'un grand pas en avant pour l'éducation médicale, un essai randomisé unique mené par une équipe de chercheurs estimés de l'Université de Toronto a révélé que la technologie PrecisionOS est aussi efficace que les cadavres traditionnels pour enseigner l'anatomie. L'étude, dirigée par Robert Koucheki, MD, Peter Ferguson, MD et Barbara Ballyk, PhD, a retenu l'attention au cours des derniers mois depuis sa publication.

Traditionnellement, l’étude de l’anatomie s’appuie fortement sur des os de scie ou des spécimens cadavériques, qui peuvent présenter des défis en termes de disponibilité, d’accès, de préservation et de considérations éthiques. PrecisionOS a développé, de concert avec des chirurgiens et des anatomistes médicaux, une alternative prometteuse à travers une expérience de réalité virtuelle 3D immersive et interactive. L'application PrecisionOS Virtual Reality Anatomy simule des structures réalistes et anatomiquement précises, permettant aux étudiants d'explorer, de démonter et d'apprendre dans un environnement virtuel.

Le essai contrôlé randomisé, menée dans le laboratoire d'anatomie de la prestigieuse faculté de médecine Temerty de l'Université de Toronto, a impliqué 50 nouveaux étudiants en médecine de première année qui devaient commencer soit par PrecisionOS, soit par l'apprentissage sur cadavre. Les étudiants se sont d’abord concentrés sur l’anatomie des membres supérieurs avant de passer à l’étude de l’anatomie des membres inférieurs à l’aide de l’outil pédagogique alternatif. Le critère d'évaluation principal de l'étude était le changement de performance entre les tests de connaissances pré-intervention et post-intervention.

Les résultats ont montré des connaissances équivalentes acquises entre l’expérience PrecisionOS Anatomy et les cadavres. Ces résultats s'ajoutent à la validation et aux preuves en cours pour la solution PrecisionOS tout en offrant des avantages significatifs d'une plus grande accessibilité et d'une plus grande réutilisation, ce qui entraîne une réduction des coûts.

De plus, les participants à l’étude ont été interrogés pour évaluer leurs impressions sur PrecisionOS en tant qu’outil pédagogique. Un nombre impressionnant de 801 TP3T de participants ont trouvé PrecisionOS très utile pour enseigner l'orientation tridimensionnelle, les relations anatomiques et les repères clés. Cela correspond à l’opinion majoritaire selon laquelle une combinaison de méthodes traditionnelles et de PrecisionOS améliorerait l’apprentissage dans le domaine de l’anatomie.

“Anatomy forms the foundation of knowledge across all specialties in healthcare” said Dr Danny Goel, Orthopedic Surgeon and CEO of PrecisionOS. “Creating a product that is proven through independent research validates both the use and the opportunity for learners around the world. This study adds to the ongoing validation we are seeking to demonstrate the value of our software across the entire medical ecosystem”.

Le Dr Koucheki et son équipe estiment que cette recherche a des implications considérables pour les facultés de médecine du monde entier, en particulier celles qui sont aux prises avec des défis liés à l'acquisition de cadavres humains et de parties de cadavres. L’étude souligne le potentiel de PrecisionOS à démocratiser l’accès à une éducation anatomique de haute qualité, remodelant ainsi le paysage de la formation et de l’éducation médicales.

“This study highlights the transformative power of PrecisionOS in medical education,” remarked Dr. Ferguson, lead Orthopedic Surgeon and Chair at the University of Toronto. “We are excited to pave the way for a more inclusive, accessible, and effective approach to teaching clinically and surgically relevant anatomy.”

Les résultats de cet essai sont sur le point de stimuler l’innovation dans la formation médicale et pourraient influencer la conception des programmes d’études dans diverses spécialités, notamment les domaines chirurgicaux et orthopédiques. La recherche a été publiée dans le Journal of Surgical Education, fournissant une ressource précieuse aux éducateurs, aux professionnels de la santé et aux chercheurs.

21 Months of Automated VR Data

MAJOR ACADEMIC ORTHOPAEDIC RESIDENCY PROGRAM

How self-directed VR practice fills the seams of the clinical day and produces measurable learning trajectories—completely automatically.

Executive Summary:

Over a 21-month period, 30 orthopaedic residents integrated immersive VR into their training curriculum. With a simple, weekly requirement for residents to practice in headset, the platform seamlessly captured over 88,000 structured data points across 2,566 practice sessions. The resulting data proved that when residents have access to high-fidelity, frictionless simulation and are motivated, they will hone their skills and demonstrate clear performance improvements.

Frictionless Adoption: Practice doesn't compete with clinical time. The data revealed that 45% of all sessions happened organically during lunch breaks or on weekends.

Comprehensive Coverage: Usage wasn't limited to a single subspecialty. Residents attempted 61 distinct cases across 27 procedure modules, proving active engagement from Foundations & Anatomy to Complex Trauma.

Measurable Improvement: The platform didn't just track usage; it tracked skill acquisition. Across 288 scored playthroughs, longitudinal data showed a clear performance signal, with residents demonstrating an average positive learning delta of +0.36 over time.

From Uncertainty to Execution

“You already have a plan, now you’re just executing it.”

The Story: Bridging the "Intern Gap"

Dr. Andrew Maeso recognizes the steep reality of residency: “As an intern, you are thrown into the fire.” For him, the hurdle wasn’t just the surgery—it was the invisible mechanics (positioning, X-ray angles, and workflow) that move too fast to learn in a high-pressure OR.

The Solution: Access Over Policy

By bringing the PrecisionOS ecosystem home, Dr. Maeso replaced passive YouTube watching with active mental rehearsal. This allowed him to arrive in the OR with the “steps” already hard-coded into his muscle memory.

The Game Changer: Personal headsets issued for at-home, 24/7 training.

Clinical Focus: Mastery of Antegrade Femoral Nails and Shoulder Arthroscopy.

Program Growth: Experience led to secured funding for all incoming residents.

Dr. Ryan Lohre

MGH Staff Surgeon

From Resident to MGH Staff Surgeon

“Prepare like it matters. Because in the OR—it does.”

The Story: The Currency of Trust

Dr. Ryan Lohre’s trajectory changed during a complex pediatric case that had already seen two failed attempts by tenured surgeons. While textbooks offered the theory, Dr. Lohre used VR to master the 3D spatial intelligence required to build a mental model of the deformity and navigate C-arm imagery in real-time.

The Solution: The 18-Minute Sandbox

The night before surgery, Dr. Lohre rehearsed the procedure four times in VR from his own home. This high-fidelity rehearsal allowed him to arrive in the OR functioning at 80-90% proficiency, compared to the typical 10-20% for a resident facing a new, complex procedure.

The Game Changer: 18 minutes of at-home VR prep for a complex pediatric case.

Clinical Focus: Spatial intelligence for C-arm interpretation and screw trajectory.

Program Growth: Transitioned from trainee to Staff Surgeon at Mass General.

Teaching with Surgical Efficiency

“I let the junior resident do more than ever before—and still finished on time.”

The Story: Reclaiming the OR

While at West Virginia University (WVU), Dr. Barry McDonough faced a universal challenge: balancing resident education with strict OR efficiency. By the time residents step into the OR, foundational skills like camera handling and triangulation should be second nature—not a distraction that slows down the case.

The Solution: Independent Preparation

Residents were assigned just 10 minutes of asynchronous VR training per week. This allowed them to master the “invisible” basics of arthroscopy on their own time. With an average of 17 sessions completed during the pilot, residents arrived with a mental roadmap that translated into immediate technical fluency.

The Game Changer: Asynchronous prep—residents train independently at home.

Clinical Focus: Mastery of triangulation, scope control, and anchor placement.

Program Growth: Model expanded across trauma, spine, and upper extremity.

Dr. Charlie Spieser

Orthopedic Resident

Mastering the Visuo-Spatial Gap

“VR practice shifts questioning from case generalizations to technique refinement.”

The Story: From Application to Confidence

Charlie Spieser highlights a universal resident hurdle: the high-stress transition from “book knowledge” to real-world execution. Early in training, the fear of making irreversible decisions can lead to hesitation. To bridge this gap, Charlie utilized VR as a daily resource for kinetic learning and anatomical association.

The Solution: Refining Spatial Intelligence

Unlike textbooks or passive videos, PrecisionOS allowed Charlie to practice high-stakes approaches—such as the anterior total hip—in a guided, 3D environment. This repetition provided a “safe sandbox” to identify why errors occurred, building the visuo-spatial confidence required to navigate complex anatomy before ever entering the OR.

The Game Changer: Daily Integration—normalized as an expected program resource.

Clinical Focus: Anterior Total Hip and Deltopectoral surgical approaches.

Program Growth: Nuanced Mentorship—shifting focus to specific faculty preferences.

How consistent iVR training accelerates technical fluency and attending trust for first-year residents.

Executive Summary: This case study follows a first-year resident’s integration of immersive VR (iVR) into their surgical curriculum. By dedicating consistent training time to virtual modules, the resident was able to master procedural steps and receive real-time feedback in a risk-free environment before ever stepping into the operating room. The study highlights that this deliberate practice led to a “noticeable improvement in overall efficiency” and significantly increased the attending’s trust and confidence in the resident’s intraoperative capabilities.

Muscle Memory Development: The repetitive nature of immersive VR (iVR) training, combined with constant real-time feedback, allows technical surgical steps to become deep-seated muscle memory.

Measurable Efficiency Gains: Residents utilizing the platform observe a "noticeable improvement" in overall efficiency and technical proficiency when performing complex orthopedic procedures.

Accelerated Attending Trust: Preoperative rehearsal in a virtual environment significantly increases attending surgeon confidence, directly leading to increased autonomy for the resident in the operating room.
