title: Cervical myeloradiculopathy caused by arthrotic hypertrophy of the posterior facets and laminae.
abstract: Five patients with typical cervical myeloradiculopathy caused by focal cervical spinal stenosis are presented. Dorsal intrusions into the spinal canal by hypertrophied apophyseal joints and thickened laminae resulted in cord and nerve root compression. Minor spondylotic changes were present in the floor of the spinal canal. Laminar decompression with formainotomy and facetectomy relieved the patients of their symptoms. An anterior approach should not be considered in the management of this disorder. Our findings of severe apophyseal arthrosis with lesser degrees of associated spondylosis are similar to those described in anatomical studies by other authors. While uncommon, myelopathy caused by dorsal compression of the spinal cord and nerve roots deserves specific mention so that therapy can be directed to the proper quadrants of the spinal canal wherein the significant pathology is located.
