The Spatial Orientation of The Foot: A Critical Step in Hindfoot Alignment Evaluation on Weight Bearing CT

Video Transcription

Video Summary

In this video, Shuyuan Li presents research on the spatial orientation of the foot and its importance in hindfoot alignment evaluation using weight-bearing CT scans. The collaborative study involved researchers from the University of Colorado, Steps to Walk, and Beijing Turing Hospital. The video highlights that current measurements used for weight-bearing CT analysis are based on two-dimensional concepts, and foot positioning is crucial for accurate alignment evaluation. Images are shown to demonstrate how different foot positions can manipulate a neutral hindfoot into varus or valgus alignment. The study confirms that changing foot orientation significantly affects hindfoot alignment, which may impact clinical decision-making. The need for advanced three-dimensional measurements with more rotation stability in weight-bearing CT is also stressed.
