Lateral talar process fractures or snowboarder fractures are talus fractures that can mimic a lateral ankle sprain. It may be an isolated fracture or occur as a component of more complex ankle fractures.
Mechanism of injury: The fracture occurs when the foot is dorsiflexed and inverted, as can happen with snowboarding (hence the term "snowboarder fracture"). A fracture should be suspected when there is soft tissue swelling inferior to the lateral malleolus.

Stigmata of recent hemorrhage
The stigmata of recent hemorrhage are endoscopically identified features that have a predictive value for the risk of further bleeding and thus help to determine which patients should receive endoscopic therapy.
