Atlas hypoplasia as a cause of high cervical myelopathy. Case report.
A high cervical myelopathy due to atlas hypoplasia is described in a 56-year-old man; the condition caused marked segmental compression of the spinal cord. A remarkable neurological recovery followed decompressive laminectomy of the atlas and adjacent regions. The authors discuss the embryology and etiology of this anomaly.
