Are C6 and C7 cutaneous nerves involved in cervical radiculopathy?
The rates of C6 and C7 cutaneous nerve involvement were significantly lower than those of the C5 and C8 nerves.15–17 In clinical epidemiology, 80% of cervical radiculopathies involve C6 or C7 roots.18 This indicates that not only cutaneous nerves but also other nerves convey the scapular pain secondary to cervical radiculopathy.

What are the symptoms of C3 & C4 root compression?
C3 root compression is very rare and may present with pain and numbness around the mastoid and pinna. C4 root compression may cause pain and numbness in the back of the neck, over the scapula, and sometimes the anterior chest. The symptoms and signs of lower cervical root compression are shown in table 1.

How does a C5 ramus change to a cutaneous nerve?
Under the skin, the C5 dorsal ramus changed to a cutaneous nerve at the C6 or C7 spinous process level, and gradually descended inferolaterally to the suprascapular region. The C8 dorsal ramus changed to a cutaneous nerve at the T1 or T2 spinous process level and ran from the interscapular region to the middle of scapular region (Fig. 3a).

What causes nerve root compression?
The causes of nerve root compression were associated with laterally herniated discs (n=9), spondylotic osteophytes at the Luschka or facet joint or both (n=15), and a haematoma in the ligamentum flavum (n=1). 20 of these 25 patients underwent surgery.
