Late laminectomy in traumatic paraplegia.

Long-term observation in cases of spinal injury with subarachnoid block, treated by laminectomy and removal of compressing elements, shows worthwhile results in a good percentage. Twenty-seven cases of fractures of the spine at the dorsolumbar and lumbar levels with conus and cauda equina injury were treated by laminectomy and decompression from 6 to 12 weeks after the injury, and have been followed for periods of 3-27 years. Surgical intervention was offered only in those cases in which myelography demonstrated a subarachnoid block. Most of the cases were operated on at 6-12 weeks after the injury. Displaced laminae, thickened ligamentum flavum, and arachnoidal adhesions were the common causes of compression. In six cases there was also an arachnoid cyst. Long-term follow-up showed improvement in bladder function in 14 of 27 patients, and in motor function in 8 of 27. In dorsolumbar and lumbar injuries in which there is a subarachnoid block, decompressive laminectomy is a worthwhile procedure.

Worldwide survey of neurosurgical training requirements and certifying mechanisms: report of the Committee on Neurosurgical Education of the World Federation of Neurosurgical Societies.

This is the report of the Committee on Neurosurgical Education of the World Federation of Neurosurgical Societies, which report was presented at the Seventh International Congress of Neurological Surgery in Munich in July 1981. The Committee was charged to conduct a survey of neurosurgical training requirements and certifying mechanisms throughout the world. These data are summarized in the tables in this report.

Absence of limitation of straight leg raising in proved lumbar disc lesion: case report.

The absence of the classical clinical sign of limitation of strainght leg raising is reported in one patient and summarized in 14 others who had all the other clinical signs of disc protrusion and in whom the disc lesion was proved by myelography and at surgery. It is postulated that the absence of this important sign may be explained by the daily habits of patients who stoop and bend to perform their household duties. Such posture leads to an elongation of the nerve roots, which permits a full range of straight leg raising. It is worth remembering that this sign may be absent in some patients with a disc lesion.

Convulsions with meningiomas: incidence and significance.

In a study of a consecutive series of 127 surgically treated meningiomas, it was found that 29% of the patients had reported with convulsions as their initial symptom. In this group, surgical excision of the meningioma stopped the convulsions in about half of the patients, but the others continued to have seizures after their operations. Among those patients with meningiomas who did not have preoperative convulsions, about one-sixth (15 patients) developed postoperative seizures. Patients in both groups required prolonged anticonvulsant medication. Factors predisposing to the occurrence of postoperative seizures were the site of the tumor, faulty surgical technique, and a preoperative history of seizures.

Contemporary methodology of stereotactic neurosurgery.

A survey of stereotactic operations from neurosurgical centres, one in Madras and the other in Bratislava, shows that many stereotactic operations are of the combined type. From a methodological viewpoint, stereotactic preformances may be divided into simultaneous, successive, symmetrical, asymmetrical, and one-sided, respectively. Thus, the stereotactic operation differs from the traditional concept that the patient may be cured by a single surgical performance. The stereotactic treatment usually consists of a succession of tactical steps, which make up the strategy of the whole treatment.
