A validation study of a novel metacarpal simulator: The next step in hand fracture fixation training

Simulated bones play a crucial role in surgical training, yet existing models vary in fidelity and cost. We developed a novel, low-cost, high-quality SLA 3D-printed metacarpal to enhance hand trauma training. Our design incorporates novel cortico-medullary differentiation to replicate the tactile fe...

Description
Summary:Simulated bones play a crucial role in surgical training, yet existing models vary in fidelity and cost. We developed a novel, low-cost, high-quality SLA 3D-printed metacarpal to enhance hand trauma training. Our design incorporates novel cortico-medullary differentiation to replicate the tactile feedback experienced when drilling through real bone. Our device was tested across 3 centres with 17 hand surgeons providing feedback. Overall surgeons highly rated our device, with it outperforming homogenous control simulators. All surgeons agreed that it had the potential to enhance surgical training. We have addressed the single use aspect of our devices by partnering with a plastic upcycling firm to repurpose used simulators, minimising landfill waste. We look forward to implementing our device in surgical training, whilst further improving it via the addition of built in fractures and a soft tissue envelope.
