Defining Normal Values for Distal Tibiofibular Syndesmotic Space With and Without External Rotation Stress: A Prospective Study with Volunteer Controls

Video Summary

In this video, Taylor Dunhartog, a third-year resident at the University of Iowa, presents a topic on defining normal values for tibiofibular syndesmotic space. The diagnosis and treatment of distal tibiofibular syndesmosis (DTFS) injury and instability can be challenging. Conventional radiographs may not accurately assess subtle instability, and MRI might miss dynamic instability. Arthroscopy is the gold standard but is invasive and costly. The paper discusses studies on the syndesmotic area in patients with syndesmotic instability and presents findings from research on healthy volunteers. External rotation stress did not result in significant widening of DTFS in healthy ankles. The baseline value for DTFS in healthy ankles with external rotation stress was measured at 103.8 millimeters squared.
