A Case Report of C8 Radiculopathy presenting as Ulnar sided Wrist Pain

Abstract

Background: Ulnar-sided wrist pain is typically attributed to local wrist pathology; however, proximal causes such as cervical radiculopathy may rarely mimic these conditions. C8 nerve root compression can produce pain along the medial forearm and ulnar wrist due to dermatomal overlap. Recognition of this atypical presentation is important to avoid misdiagnosis and inappropriate treatment. 
Case summary:  A 30-year-old man came to orthopaedic OPD with ulnar sided wrist pain on right side of 4 months duration. He had consulted 4 orthpaedicians previously and taken multiple treatments but got no relief. X-rays and MRI of the wrist were normal. Detailed examination revealed that it was radicular pain from the C8 root. Appropriate treatment was given and complete cure obtained. 
Conclusion: C8 radiculopathy may present as isolated ulnar wrist pain and mimic primary wrist disorders. Careful neurological examination and cervical spine evaluation are essential in patients with unexplained ulnar-sided wrist pain. Awareness of this presentation can help prevent misdiagnosis and guide appropriate management.
