Study Gauges 1D, 2D, and 3D Weight-bearing CT to Diagnose Syndesmotic Instability
A study presented Wednesday aimed to evaluate the ability of weight-bearing computed tomography to diagnose syndesmotic instability using 1D, 2D, and 3D measurements among patients with unilateral Weber B lateral malleolar ankle fractures. The patients in the study did not demonstrate widened medial clear space on initial radiographs yet demonstrated operatively confirmed syndesmotic instability.
