Stenotic conditions of the lumbar spinal canal: changes in surgical techniques in the management of low back disability.

The diagnostic recognition of acquired stenotic conditions in the lumbar spinal canal occurring from the fifth to the eighth decades of life had led to a significant change in surgical techniques during the last ten years. This communication presents a comparison of surgical techniques used by the author in two consecutive series of patients operated for low back, lumbosciatic, and spondylotic caudal disability syndromes during the period 1965 to 1969 inclusive (100 patients) and 1976 and 1977 (105 patients). Interlaminar discectomy was carried out in 88%, and laminectomy with spinal nerve nerolysis in 12%, of the 1965 - 1969 series. Discectomy by interlaminar approach was carried out in only 10% of the 1976 - 1977 series; all other patients had laminectomies with or without discectomies. Early follow-up results in the recent series indicate a significant (20%) increase in the number of patients who resumed their previous occupations as compared with those in the previous series.

Displacement of cerebellar tissue into spinal canal. A component of the respirator brain syndrome.

Displacement of cerebellulr tonsillar tissue into the subdural and subarachnoid space around the spinal cord was found at autopsy in eight patients who had had a variety of neurological diseases. The common factors were brain swelling and prolongation of survival by the respirator from 14 to 96 hours. Superimposed massive edema and intravitam autolysis caused by the artificial prolongation of life was the final outcome and is the most important factor in the pathogenesis of this condition. Unless the spinal cord has been examined, many pathological changes will not be appreciated.

[Morphologic changes in tissues of the spinal canal in the radicular syndromes of lumbar osteochondrosis].

Study of biopsy material obtained from 612 surgical patients with vertebrogenic diseases of spinal radicles at the lumbosacral level and collation of the morphologic findings with the clinical picture of the disease revealed a correlation between the clinical manifestations and the inflammatory process in the vascularized tissues of the vertebral column. The severity of pain was found to depend on the degree of inflammatory changes in the epidural cellular tissue and spinal membranes. The frequency and severity of inflammatory reactions make it possible to consider inflammation, along with compression and ischemia, an important pathogenetic mechanism of the development, progression and course of the discogenic radicular syndrome and to recommend the inclusion of antiinflammatory drugs in multiple modality treatment of the disease as a method of pathogenetic therapy.

[Metastases of the spinal canal--clinical aspects and surgical results].

48 patients (31 men, 17 women) were operated on because of a metastic tumour of the spinal canal. The average age at the time of operation being 53 years. After a mean duration of the disease of 6 months 43 patients were operated on with severe transverse lesions. A primary carcinoma was known in 11 patients. After the operation an improvement was observed in 17 patients. The mortality in a period of 2 weeks after the operation was 21%, and after 8 weeks 42%.

Lumbar spinal canal size of sciatica patients.

Seven measures at the three lowest lumbar interspaces were recorded from conventional radiographs of the lumbar spines of 160 consecutive patients with low back pain and sciatica admitted for myelography and possible surgery. Eighty-eight patients were operated upon for disc herniation, and of the conservatively-treated 72 patients, 18 had a pathologic and 54 a normal myelogram. The results were evaluated after one year using the occupational handicap scales of WHO. Correlations of radiographic measures to stature were moderate and to age small. After adjusting for stature and age, only the male interpedicular distances and the antero-posterior diameter of intervertebral foramen at L3 were greater than those of females. The males with a pathologic myelogram had smaller posterior disc height at L3 and a smaller interarticular distance at L3 and L4 than those with normal myelogram, likewise the midsagittal diameter at L3 and L4 in females. In all patients other measures besides posterior disc height were smaller than those for low back pain patients (p less than 0.001) or for cadavers (p less than 0.001). The only correlation between measures and clinical manifestations was between pedicular length at L3 and limited straight leg raising. Where the disc material had been extruded into the spinal canal, the interpedicular distance was significantly wider. Only anterior disc height at L3 revealed differences between good and poor outcome one year after surgery, as did the interarticular distance at S1 in patients with normal myelogram after conservative treatment.

Teratomatous cyst of the spinal canal. Case report.

A search of the English literature revealed 46 cases of primary intraspinal teratomas, of which 22 were teratomatous cysts of spinal cord. To clarify the confusion regarding this rare lesion, the definition, origin, presentation, and histological features of the lesion are discussed. An additional case is presented.

Examination of epidural tumors of the spinal canal. Comparative study with magnetic resonance imaging, computed tomography and tomo-myelography.

To delimit the vertical extension of epidural tumors of the spinal canal, tomo-myelography and magnetic resonance imaging (MRI) are the most accurate examinations, MRI appearing to us to be even superior to tomo-myelography. To evaluate precisely the bone extension of tumor growth as compared with the epidural lesions, computed tomography (CT) is more accurate than the other methods mentioned. The choice between these three techniques is of great importance as an aid in selection the best therapeutic method in each particular case.
