Patient Positioning
Patient seated in front of the examiner, hand palm up resting on the examination table.
Probe Positioning
Place the transducer on a longitudinal planes over the palm. Do not use any pressure – especially while looking for effusion or using doppler mode. Use dynamic scanning to check the movement of the tendons during flexion / extension or against resistance to check its continuity.
Patient who received a volar plate after distal radius fractur, a few months later acute, short pain. After the pain inability to flex actively the thumb. Ultrasound shows a complete tear of the FPL-tendon, which moved in direct neighbourhood to the volar plate and screws, which have damaged the tendon. The videos show transverse planes by moving the probe from proximal to distal – the stumps of the tendons are seen lateral to the median nerve and intact FCR tendon.
