Weightbearing CT Assessment of Medial Clear Space Volume Changes in Weber B Fractures: A Preliminary Analysis.

ABSTRACT:

Background

The clinical treatment of Weber B fibular fractures has primarily focused on the symmetry of the medial clear space. Numerous radiographic studies demonstrate no change in tibiotalar contact area until the deltoid ligament is disrupted. In contrast, more recent studies using weightbearing CT scan (WBCT) and 3D volume analysis suggest that medial clear space (MCS) volume can in fact increase in the setting of a Weber B fibular fracture even if initial radiographs are reassuring, possibly because of a loss of fibular buttress. This study aims to evaluate the ability of WBCT to quantify the impact of isolated Weber B fractures on MCS volume (3D), as well as understand the implication of increasing fibular displacement among patients with a symmetric MCS distance (1D) on ini
