We report the case of a 71-year-old man with impaired left finger extension. The presence of nodular fibrosing lesions in his palm suggested Dupuytren contracture as the diagnosis. However, detailed neurological examination revealed muscle weakness associated with C7-Th1 lesions, and needle electromyography revealed denervation within the same distribution. Therefore, the patient was diagnosed with distal-type cervical spondylolisthesis muscular atrophy complicated with Dupuytren contracture. Due to shared symptoms with impaired finger extension, the other two conditions can be overlooked in patients affected by both diseases. Detailed clinical investigation of nodular fibrosing lesions, muscle weakness at the C7-Th1 level, and needle electromyography findings facilitate differential diagnosis of Dupuytren contracture and distal-type cervical spondylolisthesis.
