Kinematic analysis of ankle eversion sprain in sports: two cases during the FIFA world cup

摘要

Background: The ankle is one of the most commonly injured joints with sprains. In the all ankle sprains, nearly 85% are lateral sprains, while, medial sprains, which also known as the eversion ankle sprain, are less common than lateral ankle sprains. However, medial sprains are typically associated with subsequent syndesmosis injury or medial malleolus fracture, and represent a more disabling problem, requiring longer recovery and different treatment. A precise description of the injury situation is a key component to understanding the injury mechanism and preventing injuries. However, quantitative analyses on injury cases with calibrated video recording are available only under rare circumstances. Instead, injuries in sports are occasionally shown on television with multiple camera views, by using a novel biomechanical motion analysis technique, model-based image matching (MBIM), those videos could be further analyzed. The purpose of this study was to present the 3-dimensional ankle joint kinematics of two ankle eversion sprain cases.
