syndesmotic injury
Pronunciation: sin-DEZ-mot-ik
Injury to the fibrous ligaments connecting the tibia and fibula, affecting ankle stability.
Full Definition
A syndesmotic injury, commonly referred to as a 'high ankle sprain' in sports medicine, involves damage to the syndesmotic ligaments that connect the distal tibia and fibula. These injuries can range from mild ligamentous strain to complete disruption with diastasis (separation) of the tibiofibular joint. Syndesmotic injuries often accompany ankle fractures, particularly Weber B and C patterns, and can significantly affect ankle biomechanics and stability. Diagnosis may require stress radiographs or MRI, and treatment ranges from immobilization for minor injuries to surgical fixation with syndesmotic screws for complete disruptions.
Usage
Usage note: Often called 'high ankle sprain' in lay terms but use 'syndesmotic injury' in medical contexts. Specify degree of injury when possible.
