Ultrasound-Guided Partial Release of Transverse Carpal Ligament in Severe Carpal Tunnel Syndrome Using a Curved Needle.

Ultrasound (US) is an excellent tool for diagnosis and management of carpal tunnel syndrome (CTS). Severe, recalcitrant CTS is an indication for complete release of the transverse carpal ligament (TCL). However, complete TCL release may be associated with postprocedural pillar pain. US-guided partial division of the TCL using a curved needle can be a safe and effective technique for reducing the tensile compression onto the median nerve while mitigating the occurrence of pillar pain.
