Carpal tunnel syndrome perineural infiltration median nerve

Carpaltunnel proximal transverse

Patient Positioning

Patient seated in front of the examiner, hand palm up resting on a examination table.

Probe Positioning

Place the transducer on a transverse plane over the proximal carpal tunnel - bony landmarks are: the pisiform ulnar and the scaphoid tubercle radial.

Carpaltunnel distal transverse

Patient Positioning

Patient seated in front of the examiner, hand palm up resting on a examination table.

Probe Positioning

Place the transducer on a transverse plane over the proximal carpal tunnel- bony landmarks are: the pisiform ulnar and the scaphoid tubercle radial. Then move the probe distally on transverse planes to the level of the trapezium tubercle (radial) and the hamate hook (ulnar).
