近位型頚椎症性筋萎縮症の手術成績

Cervical spondylotic amyotrophy, which causes upper limb muscle atrophy due to cervical spondylosis, results from compression lesions and circulatory disorders in the anterior horn of the spinal cord, the anterior root, or both. In the proximal type, the main symptom is the deltoid muscle and biceps brachii muscle atrophy, whereas the distal type involves muscle atrophy of the fingers. Several studies have reported various treatment outcomes concerning conservative treatment, anterior surgery, and posterior surgery for these pathologies ; however, treatment options remain controversial.
