Probe Positioning
Place the transducer on a longitudinal planes over the palmar aspect of the finger of interest. 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 the pulleys.
note: patient suffers from pain and recurrent swelling of the distal finger after a trauma with a broken glass ampule. X-ray was negative. The high resolution ultrasound reveals a small, hyperechoic structure. The structure was open resected – a small glass splinter.
