About this trial
This prospective randomized controlled study aims to compare the analgesic effectiveness of ultrasound-guided cervical medial branch block and ipsilateral cervical erector spinae plane block in patients with cervical facetogenic pain.
Patients with chronic cervical facet-mediated pain will be randomized into two intervention groups. Pain intensity, functional status, meaningful pain response rates, analgesic consumption, and patient satisfaction will be evaluated during follow-up.
The primary objective is to determine whether cervical erector spinae plane block provides comparable short-term pain relief to cervical medial branch block.

Trial outcomes
Primary outcomes
1
Meaningful Pain Response
Proportion of patients achieving at least 50% reduction in Numeric Rating Scale (NRS) pain score during the early post-procedural period.
Time frame
Time Frame: 1 hour after the procedureSecondary outcomes
1
NRS24
Change in pain intensity measured using the 11-point Numeric Rating Scale (0=no pain, 10=worst imaginable pain).
Time frame
at 24 Hours2
NRS1
Change in pain intensity measured using the 11-point Numeric Rating Scale.( 0=no pain, 10=worst imaginable pain)
Time frame
1 week after the procedure3
NDI
Functional disability associated with neck pain assessed using the Neck Disability Index.0 = no disability 50 = complete disability Higher scores indicate greater neck-related functional disability (worse outcome).
Time frame
Baseline and 1 week after the procedure4
GPE
Patient-reported global improvement evaluated using a 7-point Global Perceived Effect scale. The GPE scale ranges from -5 to +5, where: -5 = vastly worse 0 = no change +5 = completely recovered
