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

Video Transcription

Video Summary

In the video, Rohan Bhimani discusses the arthroscopic assessment of syndesmotic instability. Syndesmotic instability occurs in the coronal, sagittal, and translational plane. The lateral hook test is commonly used for arthroscopic evaluation of the syndesmotic joint. The study aimed to determine the impact of angulation on coronal plane measurements and the minimum force required for assessing instability using the lateral hook test. A cadaveric study was conducted on ten fresh-frozen above knee cadavers. The results showed that posterior directed force resulted in larger diastasis compared to neutral or anterior directed pull. A force of 60 newtons was found to be the threshold for distinguishing between stable and unstable syndesmotic joints. Further studies are recommended for the applicability of these findings in diagnosis and management. The video is presented by Rohan Bhimani.
