Patient Positioning
Patient seated in front of the examiner, hand palm up resting on a examination table.
Probe Positioning
Place the transducer on a longitudinal planes over the joints and tendons 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: during dynamic scanning only the deep flexor tendon moves.
note: during dynamic scanning only the deep flexor tendon moves at the beginning and both tendons can be differentiated easily.
note: patient with degenerative thickening of the flexor tendons of the finger, hypomobility during dynamic scanning.
note: patient with degenerative thickening of the flexor tendons of the finger.
note: patient with degenerative thickening of the flexor tendons of the finger, hypomobility during dynamic scanning and ganglion cyst at the level of the proximal part of A1 pulley.
