fracture simulation is crucial for understanding bone fractures and their underlying physiology and pathophysiology. To achieve this objective, a collaborative effort between the Amsterdam Skill Centre (ASC) and TU Delft (TUD) culminated in the development of an innovative fracture device. The ASC's surgical department furnished us with a set of requisites, which we meticulously classified into 12 pivotal design criteria, each associated with anticipated performance outcomes. The design approach revolved around two primary functions: fracture execution and specimen preparation. Brainstorming sessions are extensive and ultimately create an all-encompassing mind map full of actionable ideas which contributes to two conceptual designs and, combining criteria evaluation, ultimately identifying the most suitable one. The analysis focus on energy release system and stability during the impact. The materialization phase encompassed an array of metalworking processes, including chainsaw cutting, turning, milling, and drilling. AISI 304L stainless steel, S355+J structural steel, and AW-6082-T6 aluminum were used for manufacturing. Drop tests were conducted using simulation bone, homogeneous material, and reinforced material. Weight tests demonstrated the device's potential to create fractures with low impact energy and proved the stability of the constructed system. Further work is required to refine impact force estimation and cadaver specimen test. This study provides a comprehensive examination of a controllable fracture device, offering insights into its construction, potential improvements, and the exploration of a compact variant tailored for specific cadaveric regions.
