In rotational ankle injury with isolated fibular fracture, deltoid integrity is important for determining stability of ankle. Medial clear space and superior clear space in gravity stress view are parameters widely used to predict deltoid ligament tear. The purpose of this study is to report radiographic parameters in gravity stress view in normal population. ⋯ This study provides normative radiographic data for a gravity stress radiograph and supports that if measurable MCS >4mm on gravity stress view, it should be aware of an unstable ankle in supination-external rotation injury.
