Application of a Low-cost, High-fidelity Proximal Phalangeal Dislocation Reduction Model for Clinician Training

Abstract

Introduction: Patients present to the emergency department (ED) relatively commonly with traumatic closed proximal interphalangeal joint (PIPJ) dislocations, an orthopedic emergency. There is a paucity of teaching models and training simulations for clinicians to learn either the closed dislocated dorsal or volar interphalangeal joint reduction technique. We implemented a teaching model to demonstrate the utility of a novel reduction model designed from three-dimensional (3D) printable components that are easy to connect and do not require further machining or resin models to complete. Methods: Students watched a two-minute video and a model demonstration by the authors. Learners including emergency medicine (EM) residents and physician assistant fellows assessed model fidelity, convenience, perceived competency, and observed competency. Results: Seventeen of 21 (81%) participants agreed the model mimicked dorsal and volar PIPJ dislocations. Nineteen of 21 (90%) agreed the model was easy to use, 21/21 (100%) agreed the dorsal PIPJ model and 20/21 (95%) agreed the volar PIPJ model improved their competency. Conclusion:Our 3D-printed, dorsal and volar dislocation reduction model is easy to use and affordable, and it improved perceived competency among EM learners at an academic ED.

Early introduction of simulation in the medical curriculum: the MedInTo perspective

“…• Economization of resources: Early exposure to simulated scenarios and/or dummy instrumentation allows for maximizing the cost-benefit balance between early skill acquisition while reducing the economic and human costs of medical teaching and learning (44)(45)(46)(47).…”
