Appendicular skeletal trauma is the most frequent reason for admission to emergency departments, and X-ray is the first imaging modality [1–4]. Artificial intelligence (AI) holds potential to improve patient management throughout their journey in emergency departments [5]. Notably, the development of AI solutions based on deep convolutional neural networks (DCNNs) for detecting bone fractures has attracted considerable attention given the prevalence of appendicular skeletal trauma. However, AI c…
