Combined Ultrasound and Fluoroscopy Guided Cervical Transforaminal Injection

the cervical spine will be sonographically examined to determine the C7 transverse process then after lidocaine skin infiltration, a 22G spinal needle is directed towards the hypoechoic shadow of the nerve root using the in-plane technique. then 1ml of non-ionic contrast will be injected and AP and the oblique foraminal fluoroscopic view will be obtained. After confirmation of correct placement of the needle,(2ml, 8mg dexamethasone plus 1ml Lidocaine 1%) will be injected.

After AP view, alignment or squaring of the target lower end plate, an oblique foraminal view is obtained. Following lidocaine 1% skin infiltration, a 22G spinal needle is directed towards the target foramen then, the superficial ultrasound probe will be applied to delineate the foramen. The needle will be advanced \~3mm towards the dorsal root ganglia under fluoroscopic guidance. After contrast confirmation of needle placement, 2ml,8mg dexamethasone plus 1ml Lidocaine 1%) will be injected.
