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 the pulleys.
Note: Ganglion cyst originating from the STT-joint in close relation to the radial artery in a patient with CPPD.
fcr: Flexor carpi radialis tendon
Note: the synovitis of the stt-joint in a patient with cppd leads to peritendinous inflammation of the fcr-tendon, see the hyperechoic spots (cppd crystals)
