AbstractRadicular pain in the upper extremity can have a cervical origin terminating at the cervicothoracic junction (C8, T1). Review of the literature suggests cutaneous representations of T2 nerve root to the axilla, posteromedial arm, and lateral forearm, suggesting yet another source of upper extremity radicular pain. A 53-year-old female experienced insidious right upper thoracic pain radiating into the right axilla, upper arm, and lateral forearm (10/10 numerical pain rating scale (NPRS)) of 1-week duration. Medical referral suggested cervical radiculopathy, however, cervical spine examination was unremarkable. She presented with mechanical dysfunction of C8, T1; T1, T2; and T2, T3 vertebral segments with restricted cervical extension. Firm compression over the right lateral aspect of the second and third thoracic vertebrae reproduced her symptoms markedly. There was a predominance of right axillary pain. Cervical extension reproduced local upper thoracic pain. Nine treatment visits for a period of 3 weeks addressed mechanical dysfunction at the cervicothoracic junction and upper thoracic region, comprising manual therapy, corrective exercise, and pain modalities. Reduction of local tenderness, and radiating axillary and right arm pain was observed (2/10 NPRS), with improved cervical extension. The second thoracic intercostal nerve and the adjoining intercostobrachial nerve, medial antebrachial cutaneous nerve, and the posterior brachial cutaneous branch of the radial nerve are speculated to be potential symptom mediators. They have a representation to the axilla, medial and posterior arm, and lateral forearm - a representation supporting the speculation of upper extremity radicular symptoms following mechanical dysfunction of the upper thoracic vertebrae.
