A characteristic dysfunction of the hand has been observed in various cervical spinal disorders when there is involvement of the spinal cord. There is loss of power of adduction and extension of the ulnar two or three fingers and an inability to grip and release rapidly with these fingers. These changes have been termed "myelopathy hand" and appear to be due to pyramidal tract involvement. The characteristic nature of the signs permit the distinction between myelopathy and changes due to nerve root or peripheral nerve disorder. The clinical significance of these signs has been assessed against other tests and their value in management is discussed.
当脊髓受累时，在各种颈椎疾病中已观察到手部的一种特征性功能障碍。尺侧两三个手指的内收和伸展力量丧失，且无法用这些手指快速抓握和松开。这些变化被称为“脊髓病手”，似乎是由于锥体束受累所致。这些体征的特征性质有助于区分脊髓病与神经根或周围神经疾病引起的变化。已根据其他检查评估了这些体征的临床意义，并讨论了它们在治疗中的价值。
