Fractures of the calcaneus and talus are severe injuries that usually result from high-energy trauma. The calcaneus and talus are essential for the transmission of body weight, so an optimal reduction and/or fixation of fractures is required to prevent disabling consequences. These fractures almost always have an articular involvement, and an anatomical reduction is required; any residual step-off would lead to joint incongruity and secondary arthrosis.The aims of imaging are first, to guide management by describing the fracture characteristics (e.g., location, displacement, fragments, articular involvement, soft tissue compromise), and second, to detect early and late surgical complications (e.g., infection, malunion, nonunion, arthrosis, hardware issues). Although radiographs remain the first-line imaging modality for the screening of ankle and foot trauma, computed tomography is almost always required for the initial management and follow-up of the patient.
跟骨和距骨骨折是严重的损伤，通常由高能创伤引起。跟骨和距骨对于体重的传递至关重要，因此需要进行最佳的复位和/或固定，以防止造成残疾的后果。这些骨折几乎都有关节面受累，需要解剖复位；任何残余的台阶都会导致关节不匹配和继发性关节炎。影像学的目的首先是通过描述骨折特征（例如，位置、移位、碎片、关节受累、软组织损伤）来指导治疗，其次是检测早期和晚期手术并发症（例如，感染、畸形愈合、不愈合、关节炎、内固定问题）。虽然 X 线摄影仍然是踝关节和足部创伤筛查的一线影像学检查方法，但 CT 几乎总是需要用于患者的初始管理和随访。
