The goal of this research was to examine if C6 or C7 cervical spinal stenosis caused any transferred medial scapula pain. The dorsal scapular nerve is regarded to be the primary mediator of scapula discomfort of neurologic origin. Several species have dorsal root ganglion neurons with dichotomizing axons, which are thought to play a role in transferred pain. Many of the patients with medial scapula discomfort in an interventional spine clinic did not have C5 stenosis, but many of them did have C6 or C7 stenosis.
The charts of 278 patients who were diagnosed with cervical radiculopathy based on the location of pain at an interventional spine clinic throughout an 11-year period from 2008 to 2018 were reviewed. Cervical MRI imaging was performed on 135 of them. The information was gathered to see if there was a link between the severity of cervical stenosis and the location of pain on the scapula’s medial border.
Patients with ipsilateral medial scapula pain had a stenosis rate of 0.0 percent at C4, 29.5 percent at C5, 64.6 percent at C6, 49.2 percent at C7, 0.0 percent at C8, and 80 percent with C6 or C7 stenosis.
Conclusion: This is the first case of referred pain from cervical stenosis at the C6 or C7 levels to the medial scapula. The mechanism of referred pain is discussed, along with a neurobiological explanation that is both plausible and testable.
