When C8 or T1 nerve roots are compressed or injured, the condition is often referred to as a or Klumpke’s palsy (though this term is historically specific to birth injuries). c8 t1 nerve roots
While the upper cervical roots (C5, C6, and C7) govern the large, powerful movements of the shoulder and elbow, C8 and T1 are the architects of fine motor control and grip. Understanding their anatomy and clinical presentation is essential for diagnosing conditions ranging from thoracic outlet syndrome to cervical disc herniations.

High-impact trauma can stretch the upper brachial plexus (upper trunk injury) or, conversely, force the arm upward, stretching the lower trunk. High-impact trauma can stretch the upper brachial plexus
The C8 and T1 nerve roots are critical for intrinsic hand function and distal forearm movement. Isolated C8 radiculopathy presents with ulnar-distribution weakness and sensory loss, whereas T1 radiculopathy uniquely produces thenar wasting with possible Horner’s syndrome. Combined lesions result in complete hand dysfunction (Klumpke’s type pattern).
