AOFAS Weightbearing CT Scans

Summary

The current standard of evaluation for Weber SER4A fracture types remains to be the use of weightbearing radiographs and gravity stress radiographs for the purposes of analysis of medial clear space. Analysis of weightbearing in these radiographs has been shown in some literature to be highly variable. . Due to the two-dimensional nature of radiographic analysis of these fracture types, there is little known about the rotational overlap and medial rotational changes and the resulting contact pressure deviations of the injured ankle of a weightbearing patient. The primary focus of this study is to evaluate contact surface area of the injured extremity to the uninjured control using bilateral weightbearing CT scans in Weber/SER4a ankle fractures. Thereby, more holistically evaluating the true stability of the injured extremity and identifying the clinical significance of WBCT evaluation compared to the standard radiographic evaluation. The study will measure contact surface area deviations of the injured extremity to the contralateral uninjured control using bilateral WBCTS and statistical shape modeling via the MATLAB image processing toolbox for 3D imaging, as well as rotational overlap and medial rotational changes. By evaluating BMI, mechanism of injury, weightbearing radiographs, and administering bilateral weightbearing CTs the study is equipped to assess the clinical significance of contact surface area changes in the stability of these fractures.
