High-Fidelity Orthopaedic Surgical Skills Models and Resident Performance in the Surgical Treatment of Tibial Plateau Fractures.
Journal of surgical orthopaedic advances(2022)
摘要
The purpose of this study was to quantify the impact of low-fidelity simulation on resident surgical skills education. Fourteen orthopaedic surgery residents (PGY-1 through PGY-5) were separated into two, training-level-matched cohorts - an untrained control cohort (UCC) and a low-fidelity Sawbones training cohort (SAW). Together, both cohorts received didactic instruction on the soft-tissue approach, intra-operative reduction, internal-fixation, and surgical wound closure of Schatzker II tibial plateau fractures. The SAW cohort first rehearsed open-reduction, internal-fixation on radiopaque Sawbones models (Pacific Research Laboratories Inc. Vashon, WA). Both cohorts were then evaluated while performing the same procedure on high-fidelity cadaveric models (Rimasys GmbH Cologne, Germany). Surgical skill and knowledge were assessed using the objective structured assessment of technical skills (OSATS) tool, a written exam, and an after-action survey. There were no significant differences in OSATS scores or written exam scores between the two cohorts. A near-linear positive relationship (R2 = 0.9737) existed between training year and average overall OSATS score. All residents expressed a preference for surgical skills training with high-fidelity cadaveric models. The results of this study fail to demonstrate a training advantage of low-fidelity Sawbones models when surgical skill is measured on high-fidelity cadaveric models. Despite this, residents across both cohorts qualitatively felt the high-fidelity models offered a better educational opportunity for surgical practice than did the low-fidelity Sawbones models.
