Best Practice Case Studies-Trigger Finger

Video Transcription

Video Summary

This transcript from Brennan Boettcher at Mayo Clinic explains the ultrasound evaluation process for trigger finger. The case focuses on the right ring finger, using a high-frequency linear transducer. The scan highlights the FDS and FTP tendons overlying important anatomical structures and identifies key features such as edge shadowing and anechoic fluid in the tendon sheath. Trigger finger diagnosis is indicated by FDS tendon hypoecogenicity, nodule formation, and thickened A1 pulley. Dynamic visualization shows disconjugate motion and bunching, characteristic of trigger finger symptoms, confirming the diagnosis through ultrasound.
