✓ A case of cystic degeneration of the transverse ligament located posteriorly to the dens and causing compression to the lower medulla and upper cervical spinal cord is reported. The clinical, pathological, and radiological findings are described and compared to the literature to characterize this syndrome more fully. The advantages of a posterolateral surgical approach are stressed.

✓ Various cervical spinal cord lesions interrupting portions of the descending respiratory pathways were made in 12 cats. Results suggest: 1) that the descending inspiratory pathways lie in the ventrolateral portion of the high cervical spinal cord; 2) that a decussation of these pathways exists between the low medullary and high cervical level; 3) that fibers descend via both crossed and uncrossed pathways along the length of the cervical cord to innervate phrenic nuclei bilaterally; 4) that activity in the crossed pathway running along the length of the cervical cord is related to the level of PaCO2.

✓ The lower brainstem and cervical spinal cord from an ordinarily treated case of Chiari Type I hindbrain hernia associated with syringomyelia was examined using high-resolution magnetic resonance microscopy and standard neuropathological techniques. Magnetic resonance microscopy allows total screening and visualizes the disturbed internal and external microanatomy in the three orthogonal planes with the resolution of low-power optical microscopy. An additional advantage is the in situ visualization of the shunts. Afterwards the intact specimen is still available for microscopic examination. Part of the deformation of the medulla is caused by chronic tonsillar compression and molding inside the foramen magnum. Other anomalies, such as atrophy caused by demyelination, elongation, and unusual disturbances at the level of the trigeminal and solitary nuclear complexes contribute to the deformation. At the level of the syrinx-free upper part of the cervical cord, anomalies of the dorsal root and the dorsal horn are demonstrated.

Fine Print

✓ Adult dogs were rendered hydrocephalic by the injection of kaolin into the cisterna magna. One group of dogs was sacrificed 1 month after kaolin administration, and ventriculojugular shunts were performed on the other group. Hydrocephalic dogs with shunts were sacrificed 1 day or 1 week after the shunting procedure. All dogs were perfused with formalin at physiological pressure, and the brain stem and cervical spinal cord were examined by light microscopy. Subarachnoid granulomata encompassed the superior cervical spinal cord and dependent surface of the brain stem. Rarefaction of the posterior white columns and clefts or cavities involving the gray matter posterior to the central canal and/or posterior white columns were present in the spinal cords of both hydrocephalic and shunted hydrocephalic dogs. Predominantly in the dogs with shunts, hemorrhages were noted in the spinal cord in association with the clefts or cavities. A mechanism of ischemia followed by reflow of blood is postulated to explain the hemorrhages in the spinal cords of hydrocephalic dogs with shunts.

✓ Patients with Klippel-Feil syndrome are often at high risk for neurological injury. The cervicomedullary junction and cervical spinal cord are especially vulnerable. Twenty-one patients examined and treated over a 20-year period are reviewed. The salient features of the syndrome are identified, and an approach to management is proposed.

✓ A measure of mobility for patients with spinal cord injuries is introduced that is very useful in determining patient recovery. The index is used to obtain a prediction equation for motor skills 1 year after injury. Important predictor variables identified include the patient's sex, rectal status, total reflexes, two treatment combinations, motor and sensory neurological history since injury, neurological status, and initial mobility score. Interpretations are made to explain the meaning of the contributions of these variables and show the usefulness of the prediction equation.

✓ Recordings have been made from the upper cervical spinal cords of 14 intact anesthetized dogs. Small bipolar concentric electrodes were passed from posterior to anterior and the spontaneous electrical activity at different depths recorded. It has been shown that there is a difference between the activity recorded in the gray and white matter and between different regions in the gray matter. Responses evoked by contralateral electrical skin stimulation have also been recorded in the anterolateral columns. The results obtained suggest that the fibers may be arranged in the tract as a model of body image rather than segmentally. All the trajectories used in this study have been verified histologically. Possible application of this technique to the procedure of percutaneous cordotomy is discussed.
