Clinical Trial Summary

Proximal femur fractures (PFF) are a worldwide public health concern. A delay in the diagnosis and treatment worsens the prognosis. Inversion of grayscale is a tool available on most X-rays visualization software, and its use has been suggested to improve radiological diagnosis. The study aims to determine if using inverted grayscale radiography results in better diagnoses of PFF among medical students.

Material and Methods. The investigators evaluated the detection of PFF by fifth-year medical students on a series of 30 pelvis X-rays. The series was composed of 20 X-rays with PFF and 10 X-rays without fracture. A first reading session was set up where X-rays were presented separately in conventional and inverted grayscale. A second session one month later showed both grayscale visualizations together (BIcontrast X-rays Analysis Method - BIXAM). X-rays' order of appearance was randomized. The investigators performed the same evaluation on senior orthopedic surgeons as a control. Finally, sensitivity, specificity, and accuracy were assessed for each method (conventional, inverted, and BIXAM) with the McNemar test. Subgroup analyses were performed on the fracture localization (femoral neck, trochanteric).
