A Prospective Validation of Biplanar Ultrasound Imaging for C5-C6 Cervical Medial Branch Blocks.
Ultrasound (US) guidance offers an alternative to fluoroscopy for medial branch blocks of the upper cervical spine, but it may be less accurate for blocks at the C5 and C6 levels. We hypothesized that a modified technique using biplanar US imaging would facilitate level identification and provide greater accuracy for the lower cervical spine. ⋯ Ultrasound guidance using a biplanar approach is a reliable imaging modality for C5 and C6 medial branch blocks.
