Myeloradiculopathy: C8 and T1 radiculopathy

Due to rarity and overlap in sensory and motor contributions, diagnosis of C8 and T1 radiculopathies may be difficult. This may also be due, in part, to an incomplete knowledge and understanding of the brachial plexus and peripheral nerve anatomy. The C8 and T1 nerves provide sensory innervation proximal to the wrist, which is important when distinguishing between these radiculopathies and an ulnar compressive lesion. Understanding plexus anatomy will allow surgeons to distinguish between C8 and T1 radiculopathies, with particular attention to other pathologies that present with similar complaints.
