Spatial understanding of osteoarticular deformities of the foot and ankle is vital to correct diagnosis and therapeutic decision making. Poor reproducibility in conventional standing radiography in three orthogonal views has driven the development of weight-bearing computed tomography (WBCT) technology over the last decade. We analyzed the available literature on WBCT imaging in patients with foot and ankle disorders by performing a literature review of relevant clinical studies in multiple databases including PubMed, MedLine, and Scopus from January 1999 to October 2017. WBCT imaging allows correct evaluation of foot and ankle anatomy with the patient in a standing position, providing images with high spatial resolution, short image acquisition time, low dose of radiation, and costs which are similar to other available imaging technologies. This diagnostic tool can be used for decision making in the treatment of deformities of the ankle, hindfoot, midfoot, and forefoot. Level of Evidence III; Systematic review of level III studies.
对足踝部骨关节畸形的空间理解对于正确诊断和治疗决策至关重要。传统站立位X线摄影在三个正交视图中的重复性较差，这推动了负重计算机断层扫描（WBCT）技术在过去十年的发展。我们通过对多个数据库（包括PubMed、MedLine和Scopus）中1999年1月至2017年10月的相关临床研究进行文献综述，分析了关于足踝疾病患者WBCT成像的现有文献。WBCT成像能够在患者站立位时正确评估足踝部解剖结构，提供具有高空间分辨率、短图像采集时间、低辐射剂量且成本与其他现有成像技术相似的图像。这种诊断工具可用于踝关节、后足、中足和前足畸形治疗的决策。证据等级III；III级研究的系统评价。
