Comparison Between Retrolaminar and Medial Branch Block in Cervical Facet Joint Arthropathy

2- Cervical retrolaminar block: will be performed on prone-positioned patients. Under fluoroscopic visualization, after identification of the lamina at the desired level, a 25-gauge, 3.5-inch spinal needle was introduced and when the needle tip will be confirmed at the posterior aspect of the cervical lamina corresponding to cervical facet arthropathy level. 5 mL of a mixture of 3 mL 1% lidocaine and 2 mL dexamethasome (8mg/2ml) will be injected.

1- Cervical medial branch block: will be performed on prone-positioned patients using a posterior approach. Under fluoroscopic visualization, after identification of the waists of the articular pillars at the desired levels, each medial branch block was administered with a 25-gauge, 3.5-inch spinal needle. When the place of the needle tip will be confirmed at the mid-point of the waists of articular pillars, 1 ml of the mixture of 0.5 mL 1% lidocaine and 0.5 mL dexamethasome (8mg/2ml) will be injected at each level.
