Diagnostic Accuracy of Weightbearing CT in Detecting Chronic Subtle Syndesmotic Instability: A Prospective Comparative Study

Video Transcription

Video Summary

In this video, Alan Shamrock discusses the role of weight-bearing CT in diagnosing syndesmotic instability in the chronic setting. Syndesmotic instability refers to injuries to the syndesmosis, which is the joint that connects the tibia and fibula in the ankle. Prompt diagnosis and treatment of these injuries are crucial to prevent pain, dysfunction, and early osteoarthritis. The current gold standard for diagnosis is ankle arthroscopy, but weight-bearing CT offers a non-invasive alternative. The video presents a study that evaluated the diagnostic accuracy of weight-bearing CT in chronic syndesmotic instability, finding that it performed poorly compared to previous studies on acute injuries. Increasing the sample size and introducing external rotation stress may improve its diagnostic capability in the chronic setting.
