Abstract

Cuboid height is a quantitative radiographic measurement of the relationship of the inferior cuboid to the plantar osseous plane of the lateral column of the foot and might be associated with poor clinical outcomes in patients with midfoot Charcot neuroarthropathy. We evaluated the reliability of the cuboid height measured by a group of foot and ankle surgeons on subjects with midfoot Charcot neuroarthropathy. Ten board-certified foot and ankle surgeons, 10 residents, and 10 medical students measured the cuboid height on 11 lateral weightbearing radiographic projections of subjects with midfoot Charcot neuroarthropathy. Cuboid height measurements were grouped categorically with calculation of an intraclass correlation coefficient (ICC). Ten unique images were used, with 1 repeated image to provide a measure of intrarater agreement. The overall measure of reliability of cuboid height measurement was an ICC of 0.997. Specifically, the ICC was 0.987 for surgeons, 0.992 for residents, and 0.989 for students. Participants were in agreement with the repeated measure in 24 (80.0%) of 30 cases. Specifically, each group (surgeons, residents, and students) were each in agreement for 8 (80.0%) of 10 repeated measurements. In conclusion, t...Continue Reading
