Arthroscopic Assessment of Syndesmotic Instability: Are We Pulling Correctly in Coronal Plane?

Video Transcription

Video Summary

Rohan Bhimani's study investigates arthroscopic assessment of syndesmotic instability, focusing on force direction and magnitude during the lateral hook test. Using cadaver models, the study measured coronal space displacement under varied forces (0-120 N) and angulations (neutral, 15° anterior, 15° posterior). Results showed increased diastasis up to 60 N, with posterior-directed force causing larger displacements than neutral or anterior pulls. This 60 N threshold distinguishes stable from unstable syndesmoses. Findings emphasize precise force application for accurate diagnosis, as subtle instability shifts are clinically significant. Further research is needed to apply these results in clinical management.
