CT Myelography on Cervical Disc Herniation

It is difficult to diagnose a main lesion of cervical spondylosis in consideration of neurological findings when there are several abnormal findings in cervical myelography. We could diagnose 12 cervical disc herniations correctly by CT myelography after cervical myelography and treated them by anterior spinal decompression and fusion. They recovered remarkably. Therefore, we reported 12 cases of cervical disc herniations and utility of CT myelography.

A Case of Incomplete Myelopathy by Ossification of Yellow

A case of incomplete myelopathy at proxmal thoraco-lumbar spine kyphosis caused by ossifcation of yellow ligament is reported.A 60-year-old male was addmiteed to our hospital complaining of bilateral lower extremity pain and gait disturbance of 5 months duration. Motor-sensory palsy below L1, and complete block on myelogram caused by OYL on T11/12 was seen and the compression was found by CTM.We performed wide laminectomy on T11, T12, and the palsy was gradually reduced as a result of the operation. 14 weeks after operation, he was discharged on his foot.

Cervical Alignment in the Sagittal Plane Following Laminectomy

From June in 1979 to Septemenber in 1984 thirty-five patients underwent cervical laminectomy.We usually used the modified Kiritas method, and used with posterolateral fusion. Our routine technique of posterolateral fusion was a chip bone graft or the Robinsons method. These procedures were performed on thirty-four patients after laminectomy. Lateral view of these patients X-ray films were examined. Almost all patients had maintained good aligment in the sagittal plane. There was no case of the Swan neck deformity.
