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 feedback experienced when drilling through real bone.
