D evelopmental cervical canal stenosis with no radiological features of spondylosis is a recognized cause of cervical myelopathy. 3, 5–7 However, localized spinal canal stenosis due to developmental hypertrophy of the posterior neural arch of C-2 has not been reported to date as a cause of myelopathy. Case Report This 40-year-old man presented with a 4-year history of burning paresthesia and progressive stiffness of all four extremities and urgency of micturition. The paresthesia attacks lasted 2 to 5 seconds and were precipitated by flexion and

patient ordinarily complains of head drop and neck pain to some degree. Myelopathic symptoms are rare. In this case report, we describe the development of a kyphotic deformity and its potential for surgical correction. This patient had cervical myelopathy caused by dropped head syndrome. The patient underwent a C3–4 laminectomy and occipitocervicothoracic fixation for a C3–4 cord compression and C4–5 instability. Symptoms improved dramatically after surgery. Case Report History This 68-year-old woman first presented with her head hanging forward. After 1 month

T he craniovertebral junction is one of the most common sites of malformations. 3, 5, 7 One such malformation, hypoplasia of the atlas, was first described by Wackenheim 8 in 1974. Atlas hypoplasia rarely causes myelopathy; the neurological and neuroradiological findings and treatment have been reported for only one patient with this condition. 4 This paper describes a severe case of high cervical myelopathy caused by atlas hypoplasia. Case Report This 56-year-old man was admitted to Kensei General Hospital after he hit his forehead during a fall. The

F or the treatment of cervical myelopathy, anterior or posterior decompression has been advocated, and both procedures have been reported to yield generally good results. 1, 3, 4, 6, 7, 9, 23, 24 Radiculopathy of C-5, however, has been reported as a major complication of both procedures. The development of radiculopathy after decompressive laminoplasty has been intensively studied, 2, 5, 19, 20, 21, 25 whereas to date there are only a few studies of this complication after anterior decompression. 8, 10, 12–15, 22 Radiculopathy of C-5 after decompression

T here are many reports concerning the usefulness of magnetic resonance (MR) imaging in spinal surgery, especially for syringomyelia 8 and spinal cord tumors. 1 In cervical myelopathy, 2, 6 several reports emphasize the value of MR imaging because of its clear depiction of disc herniation as well as compression or deformation of the spinal cord. In 1987, Takahashi, et al. , 9, 10 reported areas of increased signal intensity in the spinal cord on T 2 -weighted images secondary to compressed cord. They thought that these findings were the result of

, 7 Moreover, cervical spine surgery for myelopathy tends to involve patients in a higher disease state than those undergoing many other elective spine surgery conditions. 8 Individuals who undergo spine surgery for cervical myelopathy report distinctively higher levels of disability, 5 greater difficulty walking, 9 and longer-term duration of symptoms such as neck, arm, and shoulder pain. 10 Although approximately two-thirds of patients who undergo surgery for cervical myelopathy report improvement, 11 surgery is generally expected to halt disease progression

characterized by the congenital fusion of any 2 of the 7 cervical vertebrae. 6 Reports on the concomitance of these clinical pictures are rare, with most cases having been identified in the pediatric population. 17 We report on a 34-year-old woman with aberrant bone growth into the spinal canal from an omovertebral bone extending from the left scapula pressing into the vertebral arch of C-6 and leading subsequently to cervical myelopathy. To the best of our knowledge, no explicit cases on this topic have been reported in the adult population to date. Case Report

, hypotension, and deprivation of oxygen. The common effect of anoxic insult is damage to gray matter, the motor neurons being more vulnerable than the interneurons. 29 Pathology of Cervical Myelopathy in Humans . Cervical cord pathology associated with spondylosis has been described in more than 70 cases, 8, 21, 55, 61, 63, 67, 83 and it has been repeatedly demonstrated that histological changes are greatest at the site of maximum compression.
