The absence of soft tissue superimposition on bone makes CT greatly superior to conventional radiographs, even using special views, for demonstrating the hind foot. Views derived from both methods are compared. Semicoronary and transverse planes have been defined in relation to specific points in the tarsus. In the semicoronary plane, the calcaneus-valgus angle varies from +10 degrees (valgus) to -10 degrees (varus) and the sustentaculum angle varies from 18 to 28 degrees. In the transverse plane, the plantar talocalcaneal angle is 60 degrees to 70 degrees and the calcaneal-cuboidal angle is 20 degrees to 35 degrees. These values are based on measurements of 62 normal feet. They are valuable for judging quantitatively posttraumatic deformities, displacement of fragments and operative results.
在显示后足方面，由于骨骼上没有软组织重叠，CT即使使用特殊投照方法也大大优于传统X线片。本文对两种方法获得的影像进行了比较。半冠状面和横断面是根据跗骨的特定点来定义的。在半冠状面，跟骨外翻角从+10度（外翻）到-10度（内翻），载距突角从18度到28度。在横断面，距下关节跖侧角为60度至70度，跟骰关节角为20度至35度。这些数值基于62只正常足的测量结果。它们对于定量判断创伤后畸形、骨折块移位及手术效果很有价值。
