Toronto, Ontario, Kanada — 8. November 2023 – In einem bedeutenden Fortschritt für die medizinische Ausbildung hat eine einzigartige randomisierte Studie, die von einem Team angesehener Forscher der Universität Toronto durchgeführt wurde, gezeigt, dass die PrecisionOS-Technologie beim Anatomieunterricht genauso effektiv ist wie herkömmliche Leichen. Die von Robert Koucheki, MD, Peter Ferguson, MD und Barbara Ballyk, PhD geleitete Studie hat in den letzten Monaten seit ihrer Veröffentlichung große Aufmerksamkeit erregt.

Traditionell stützte sich das Studium der Anatomie stark auf Sägeknochen oder Leichenproben, was hinsichtlich der Verfügbarkeit, des Zugangs, der Konservierung und ethischer Überlegungen zu Herausforderungen führen kann. PrecisionOS hat in Zusammenarbeit mit Chirurgen und medizinischen Anatomen eine vielversprechende Alternative durch ein immersives und interaktives 3D-Virtual-Reality-Erlebnis entwickelt. Die PrecisionOS Virtual Reality Anatomy-Anwendung simuliert realistische und anatomisch genaue Strukturen und ermöglicht es Schülern, in einer virtuellen Umgebung zu erkunden, zu zerlegen und zu lernen.

Der randomisierte, kontrollierte StudieAn der Studie, die im Anatomielabor der renommierten Temerty-Fakultät für Medizin der Universität Toronto durchgeführt wurde, nahmen 50 neue Medizinstudenten im ersten Jahr teil, die entweder mit PrecisionOS oder Leichenlernen beginnen sollten. Die Schüler konzentrierten sich zunächst auf die Anatomie der oberen Gliedmaßen, bevor sie dazu übergingen, die Anatomie der unteren Gliedmaßen mithilfe des alternativen Lehrmittels zu studieren. Der primäre Endpunkt der Studie war die Veränderung der Leistung von Wissenstests vor und nach der Intervention.

Die Ergebnisse zeigten, dass der Wissensgewinn zwischen der PrecisionOS Anatomy-Erfahrung und Leichen gleichwertig war. Diese Erkenntnisse tragen zur laufenden Validierung und Evidenz der PrecisionOS-Lösung bei und bieten gleichzeitig erhebliche Vorteile einer besseren Zugänglichkeit und Wiederverwendung, die beide zu geringeren Kosten führen.

Darüber hinaus wurden die Studienteilnehmer befragt, um ihre Eindrücke von PrecisionOS als Lehrmittel zu ermitteln. Überwältigende 80% der Teilnehmer fanden PrecisionOS am wertvollsten für die Vermittlung dreidimensionaler Orientierung, anatomischer Beziehungen und wichtiger Orientierungspunkte. Dies deckt sich mit der Mehrheitsmeinung, dass eine Kombination aus traditionellen Methoden und PrecisionOS das Lernen im Bereich der Anatomie verbessern würde.

“Die Anatomie bildet die Grundlage des Wissens in allen Fachbereichen des Gesundheitswesens”, sagte er. Dr. Danny Goel, “Die Entwicklung eines Produkts, dessen Wirksamkeit durch unabhängige Forschung belegt ist, bestätigt sowohl den Nutzen als auch die Möglichkeiten für Lernende weltweit. Diese Studie trägt zur kontinuierlichen Validierung bei, mit der wir den Wert unserer Software im gesamten medizinischen Ökosystem nachweisen wollen”, so der Orthopäde und CEO von PrecisionOS.

Dr. Koucheki und sein Team glauben, dass diese Forschung weitreichende Auswirkungen auf medizinische Fakultäten auf der ganzen Welt hat, insbesondere auf diejenigen, die mit Herausforderungen bei der Beschaffung menschlicher Leichen und Leichenteile zu kämpfen haben. Die Studie unterstreicht das Potenzial von PrecisionOS, den Zugang zu hochwertiger anatomischer Ausbildung zu demokratisieren und damit die Landschaft der medizinischen Ausbildung und Ausbildung neu zu gestalten.

“Diese Studie unterstreicht das transformative Potenzial von PrecisionOS in der medizinischen Ausbildung”, bemerkte Dr. Ferguson, leitender Orthopäde und Lehrstuhlinhaber an der Universität Toronto. “Wir freuen uns, den Weg für einen inklusiveren, zugänglicheren und effektiveren Ansatz zur Vermittlung klinisch und chirurgisch relevanter Anatomie zu ebnen.”

Die Ergebnisse dieser Studie werden voraussichtlich Innovationen in der medizinischen Ausbildung vorantreiben und könnten die Lehrplangestaltung in verschiedenen Fachgebieten, einschließlich chirurgischer und orthopädischer Fachgebiete, beeinflussen. Die Forschung wurde im Journal of Surgical Education veröffentlicht und stellt eine wertvolle Ressource für Pädagogen, Mediziner und Forscher dar.

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.

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.

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.
