Abstract
|
|
|
|
Cervical spondylotic amyotrophy is characterized by muscle weakness and atrophy confined to the upper extremities ithout sensory involvement. It is classified as proximal type and distal type according to the affected myotomes. It usually develops after middle- age and manifests a self-limiting course. Different diagnoses include motor neuron disease, Hirayama disease, and neuralgic amyotrophy. Conservative and surgical management are effective. Older age, longer disease duration, lower preoperative muscle power, and distal type are poor outcome factors.
