Calcaneal fracture
Conditions
Interventions
Gold Standard:Two senior radiologists who have received specialist training and possess professional practical experience in foot and ankle medicine interpret each case independently based on CT image
Index test:The indicator test is an artificial intelligence-assisted diagnostic system for calcaneal fractures based on multimodal imaging (preoperative CT and postoperative X-ray/DR). The system can

All
Inclusion criteria
Inclusion criteria: 1. Preoperative or whole-foot CT scans are available; 2. Postoperative X-rays (standard lateral + axial/Harris views) are available, and if used for "CT reference standard" assessment, corresponding postoperative CT scans within a similar time window are required; 3. Images are readable and usable for measurement/annotation (quality meets minimum standards).
Exclusion criteria
Exclusion criteria: 1. Poor image quality prevents the measurement of key parameters or the completion of annotation/interpretation. 2. A history of severe foot deformity significantly affects the assessment of anatomical structures. 3. Imaging examinations strongly suggest infection or other conditions that may significantly alter imaging findings.
