Probe Positioning
Place the transducer on transverse planes over the joints and digits of interest. Follow the tendons from cranial to distal. Do not use any pressure – especially while looking for effusion or using doppler mode.
ET: extensor tendon
ET: extensor tendon
IP: intermediate phalanx
ET: extensor tendon
Note: check the joints of interest for effusion, synovial hypertrophy, neovascularity (doppler mode) or bony / cartilage changes and periarticular calcifications. The integrity of the extensor tendon system can be check dynamically with active extension against resistance.
