Fibular malreduction is a common and important cause of pain after surgical fixation following a syndesmosis injury, but it is unclear which components of malreduction correspond to clinical outcome. Plain radiographs have been shown to be unreliable at measuring malreduction when compared to CT scans. A number of published methods for measuring fibular position rely on finding the axis of the fibula. Elgafy demonstrated that fibular morphology varies greatly, and some studies have demonstrated difficulty finding the fibular axis. We developed a new method of measuring the distal fibular position on CT images. We used CT studies in 16 normal subjects. Two assessors independently measured the ankle syndesmosis using the Davidovitch method, and our new protocol for fibular AP position, diastasis and fibular length.Introduction:
