Supination adduction ankle fractures: Ankle fracture or pilon variant?

摘要

Background: Supination adduction (SAD) fractures are rotational ankle fractures with a characteristic vertical medial malleolus fracture and tension failure fibula fracture. While these fractures are considered rotational injuries, they can have joint impaction that could lead to early joint degeneration. The purpose of this study was to characterize SAD ankle fractures and compare these injuries with partial articular pilon fractures.
