Brief Summary

The use of instructional technical surgical videos is common in orthopaedic education. Many residents have used instructional technical surgical training videos prior to medical school, as well as during their residency program, and at instructional courses. The use of instructional technical surgical videos and multimedia is considered an adjunctive training method for orthopaedic residents to learn operative procedures. Immersive virtual reality (iVR) is increasingly used in surgical education. Recently, iVR has shown transfer of skill training in orthopaedics. The continued study of the effectiveness of iVR training in orthopaedic education could benefit new competency based orthopaedics residency programs. The purpose of this study is to compare the effectiveness of instructional technical surgical video training to immersive iVR training for teaching technical skills of reverse total shoulder arthroplasty. Our hypothesis was that iVR improved learning effectiveness compared to standard technical surgical video. Secondary objectives include validating a virtual reality ratings scale through correlation to real-world performance. We proposed a randomized, blinded intervention-control trial directly comparing immersive iVR versus technical surgical instructional video training in the teaching of reverse shoulder arthroplasty in senior residents, learning at the 2020 annual Canadian Shoulder and Elbow Society meeting.

Outcome Measures

Primary Outcomes (1)

• Objective Structured Assessment of Technical Skills (OSATS)

  The Objective Structured Assessment of Technical Skills (OSATS) outcome measure is a validated assessment tool used for grading overall technical ability during surgery. This checklist contains 27 items, in which an assessor will mark off whether the task was completed successfully or not. For each item done correctly, it is worth 1 point. For each item done incorrectly, no point is awarded. All points are totalled for a maximum possible score of 27 points (minimum score of 0 and maximum score of 27). A higher score indicates a better outcome.

  During surgery up until immediately after surgery.

Secondary Outcomes (3)

• Global Ratings Scale (GRS)

  During surgery up until immediately after surgery.

• Transfer of Training (ToT)

  immediately after surgery.

• Transfer Effectiveness Ratio (TER)

  Immediately before surgery up immediately after surgery.

Study Arms (2)

Immersive Virtual Reality

ACTIVE COMPARATOR

Participants randomized to the immersive virtual reality (iVR) study arm, considered the "intervention group" will receive training on completion of a reverse shoulder arthroplasty using an iVR simulator (PrecisionOS Technology).

Other: Immersive Virtual Reality

Surgical Video

OTHER

Participants randomized to the standard video study arm, considered the "control group" will receive training on completion of reverse shoulder arthroplasty using a technical surgical instructional video.

Other: Surgical Technical Instructional Video

Interventions

Immersive Virtual Reality OTHER

Participants randomized to the iVR simulator utilizes a head-mounted display producing 3D visuals with haptic controllers for an immersive operating room experience. The module produced consists of the key steps in performing a reverse shoulder arthroplasty using virtual versions of the equipment used in the real procedure. Prior to initiation, participants will be provided with a safety and training demonstration on the use of the VR module by study personnel. Participants will be provided as much time as they require to watch the video, including repetition if desired, which they will be timed for completion.
