Fukui et al (C0/1 to C7/T1)
61 symptomatic patients with suspected facet joint pain. Pain reproduced by injection of contrast medium into the joints or by electrical stimulation of the dorsal rami. Below shows the main pain distributions from C0-1 to C7/T1, and the dorsal rami C3 to C7[2]
Joint | Pain Referral |
---|---|
C0/1 | Occipital region (30%), upper posterolateral cervical region (100%) |
C1/2 | Occipital region (20%) and upper posterolateral cervical region (100%). |
C2/3 | Upper posterior cervical region (64%), occipital region (50%), and upper posterolateral cervical region (50%) |
C3/4 | Upper posterior cervical region (76%), middle posterior cervical region (52%), and occipital region (38%) |
C4/5 | Lower posterior cervical region (76%), middle posterior cervical region (54%), and suprascapular region (43%) |
C5/6 | suprascapular region (50%),lower posterior cervical region (46%), superior angle of the scapula (35%), middle posterior cervical region (15%), and shoulder joint (11%) |
C6/7 | superior angle of the scapula (48%), mid-scapular region (41%), lower posterior cervical region (33%), shoulder joint (15%),and suprascapular region (11%). |
C7/T1 | Mid-scapular region (86%) and superior angle of the scapula (28%) |
Normal Volunteers
Dwyer et al (C2/3 to C6/7)
Pain maps with noxious stimulation of cervical facet joints in volunteers,[3] which was then validated against symptomatic patients.[4]
Dreyfuss et al (C0/1 and C1/2)
The pain referral patterns of C0-1 and C1-2 were evaluated in 5 normal volunteers.[5]
Discogenic Pain
Disc pain has very similar referral patterns to zygapophyseal joint pain. Below is the pattern of pain provoked by discography at each cervical level: C2โC3 (A), C3โC4 (B), C4 โC5 (C), C5โC6 (D), and C6 โC7 (E).
Radicular Pain
- Main article: Cervical Radicular Pain
Based off data from Rainville et al. The asterix indicates the only area where there is a statistical difference, with impaired in the distal radial aspect of the dorsal forearm more common in C6 than C7 radiculopathy[6]
Interspinous Ligaments
Referred pain patterns from noxious stimulation of the cervical interspinous ligaments. He described injecting into the midline and just off centre into the interspinous ligaments.[7]
Trigger Points
This is a clinical entity, and is very difficult to reproduce in a research setting.
