How To Assess an A4 Pulley Tear

In this video, we explore how to use ultrasound to diagnose A4 pulley injuries in the finger of rock climbers. We examine its anatomy, including its direct attachment to the bone, and how it helps keep the tendons close to the bone when gripping holds. We also show a detailed ultrasound scan of the A4 pulley, its location between the proximal and distal interphalangeal joints, and how it differs from the A2 pulley. We discuss the presentation of A4 pulley injuries and end the video by showing a normal ultrasound appearance of the A4 pulley, including its location, and its similarity to the A2 pulley/ Timecodes: 0:00 Introduction to A4 Pulley Anatomy 0:58 Detailed Ultrasound Scan of A4 Pulley 2:17 Comparing A4 Pulley to A2 Pulley 3:20 Presentation of A4 Pulley Injury 4:22 Normal Ultrasound Appearance of A4 Pulley 5:30 Transverse Image of A4 Pulley DIAGNOSITIC ULTRASOUND COURSES =============================== Ultrasound Diagnostics Level 1 Course: https://theclimbingdoctor.com/product...
