Alexander I J, The Foot: Examination and Diagnosis
Syndesmosis Injury • The syndesmosis – Stabilizes distal tibia and fibula – Keeps talus under the tibia
• The tibio‐talar surface – Must be perfectly matched – 1 mm lateral shift increases joint surface pressure by 42%
Syndesmosis Injury • A failed syndesmosis – Leads to lateral translation – tibio‐talar pressure – Promotes ankle arthritis – Results in a loss of function
