研究概览
简要总结
The purpose of this study is to compare the average joint motion and joint axis orientation of the hindfoot bones between patients diagnosed with adult-acquired flatfoot disorder (AAFD) and a control group of patients without foot deformity, using weight-bearing CT technology.

结局指标
主要结局
Change in Joint Motion Between Touch-down Bearing Navicular and Full-weight Bearing Navicular
时间窗: 1 CT scan, one reading while touch-down bearing, one reading while full-weight bearing
Relative motion, which is the position of the full weightbearing (FWB, greater that 75-100% body weight) navicular in comparison to the touch down weightbearing (TDWB, 25-50% body weight) navicular position, will be determined by comparing the joint orientation across these two points on one CT scan. The difference between the two positions is reported below.
Change in Navicular Rotation Between Touch-down Bearing and Full-weight Bearing
时间窗: 1 CT scan, one reading while touch-down bearing, one reading while full-weight bearing
Relative motion across joint segments will be determined by comparing the joint orientation across two time points: touch-down bearing (TDWB, 25-50% body weight) and full-weight bearing (FWB, greater that 75-100% body weight) as measured on CT.
