PrecisionOS® is now offering immersive virtual reality (VR) training in partnership with Siemens Healthineers. The module helps surgeons and technicians to practice the use of Siemens Healthineers’ mobile 3D C-arm Cios Spin for intraoperative quality control and surgical workflow guidance.
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.

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.

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.
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.
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.
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.
