Ultrasound-guided selective nerve root block versus fluoroscopy-guided transforaminal block for the treatment of radicular pain in the lower cervical spine: A randomized, blinded, controlled study
Skeletal Radiology, 05/24/2012
Jee H et al. – The ultrasound (US)–guided method may facilitate identifying critical vessels at unexpected locations relative to the intervertebral foramen and avoiding injury to such vessels, which is the leading cause of the reported complications from cervical transforaminal injections. Therefore, the ultrasound–guided method was shown to be as effective as the fluoroscopy–guided method in pain relief and functional improvement, in addition to the absence of radiation and avoiding vessel injury at real–time imaging.
