Medial tenderness revisited: Is medial ankle tenderness predictive of instability in isolated lateral malleolus fractures?

摘要

Introduction: Determining deltoid ligament incompetence in supination external rotation (SER) injuries commonly relies on stress radiography, given several studies demonstrating low predictive value of physical examination. Stress radiography can be difficult to obtain and may result in suboptimal radiographs with equivocal determination of stability. This study revisits the concept of medial ankle tenderness and its association with mortise instability.
