Representative X-ray images of wrist fractures. The AP (a) and lateral (b) radiographs of a distal radius fracture, which 2 of the 3 hand orthopedic surgeons misdiagnosed as without fracture, while the CNN diagnosed the fracture correctly. The AP (c) and lateral (d) radiographs of a distal radius fracture, which 2 of the 3 hand orthopedic surgeons diagnosed correctly and the CNN misdiagnosed as without fracture. The fracture is clear on oblique view (e), although this view is only for the reference and not used for validation. AP, anteroposterior; CNN, convolutional neural network
