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

Video Transcription

Video Summary

In this video, Taylor Dunhartog, a third-year resident at the University of Iowa, presents a study on the diagnosis and treatment of distal tibiofibular syndesmosis (DTFS) injury and instability. They discuss the challenges of assessing subtle syndesmotic instability using conventional radiographs and the limitations of MRI and arthroscopy. The study evaluated the differences in the DTFS area in weight-bearing and external rotation stress, using bilateral CT scans on healthy volunteers. The results showed no significant difference in DTFS area between stressed and non-stressed ankles. The baseline value for DTFS area with external rotation stress in healthy ankles was 103.8 mm².
