CME OnDemand: 2022 AOFAS Annual Meeting-New evaluation method for lateral ankle instability using ultrasound.

New evaluation method for lateral ankle instability using ultrasound.

Video Transcription

Video Summary

The video presents a new evaluation method for ankle instability using ultrasound. Ultrasound has become a standard tool in orthopedic clinics due to its simplicity, accuracy, cost-effectiveness, and minimal radiation exposure. While stress X-ray is commonly used to assess ankle instability, ultrasound can visualize ankle ligaments and evaluate ligament injuries. The study focuses on measuring fibular AP movement under manual stress to assess syndesmotic instability. The measurement items include anterior drawer distance and the lateral clear space. The results of the ultrasound measurements were comparable to those obtained using fluoroscopy, indicating that ultrasound is a useful tool for evaluating ankle instability under anterior drawer and varus stress tests. Proper measurement point setting, one-handed stress application, and probe placement are critical for accurate measurement. No credits were mentioned in the transcript.
