A Novel Low-Cost Surgical Simulation Tool for Pinning

This study seeks to validate a quantitative, low-cost simulation-based training tool for teaching orthopaedic surgery trainees the fundamentals of fracture stabilization with pins. Methods:Two low-cost models were developed with simulated cancellous bone blocks and cortical bone sheets:a pinning agility tool to teach pin placement and redirection, and a low-cost construct stability tool to replicate pinning. A lowcost ultrasound model for simulation of paediatric Ultrasound model simulation is a practical alternative for ultrasound education. 8 Hence, a lowcost poultry bone ultrasound phantom for the simulation of nonangulated buckle and greenstick paediatric distal forearm fractures was designed by the author, with adaptation from the model reported by Heiner and McArthur. 9 Materials and methods.
