    Description / Table of Contents: Summary The tethered spinal cord syndrome is more often encountered in children, but does also occur in adults. Its clinical spectrum comprises low back pain, neurological deficits such as distal motor weakness and trophic and sensory disturbances in the legs, urological symptoms and such musculoskeletal signs as scoliosis or foot deformities. In addition, cutaneous lesions or subcutaneous lipomas in the lumbosacral region may be indirect signs of an intraspinal pathology. This consists in a tight, thickened and sometimes shortened filum terminale, an intraspinal lipoma, intradural scar formation or other lesions that lead to conus fixation. The common mechanism of injury of these types of pathologies is an impairment of longitudinal movement of the spinal cord, especially the conus medullaris, which subsequently leads to chronic local ischemia. Diagnosis is most readily achieved by magnetic resonance imaging. Treatment is aimed at the restoration of cord mobility by means of microsurgical release of the conus, the cauda equina and the filum terminale with the aid of cauda equina neuromonitoring. Further progression can be effectively halted; in fact almost half of the patients actually improve. Therefore, every patient presenting with the clinical diagnosis of tethered cord syndrome should be offered specialized surgical treatment.
    Notes: Zusammenfassung Das Tethered-spinal-cord Syndrom ist ein auch bei Erwachsenen auftretender klinischer Symptomenkomplex. Er umfaßt Lumbalgien, neurologische Ausfälle, wie distal betonte Paresen, trophische und Sensibilitätsstörungen der Beine und des Gesäßes, urologische Symptome, wie Miktionsstörungen, und orthopädische Veränderungen, wie Wirbelsäulenfehlhaltungen und Fußdeformitäten. Nävi und subkutane Lipome in der Lumbosakralregion können den klinischen Verdacht auf eine für die Symptomatik verantwortliche intraspinale Pathologie lenken. Diese besteht in einem gespannten, verdickten und z.T. auch verkürzten Filum terminale oder einem intraspinalen Lipom, das den Konus des Rückenmarks fixiert. Der gemeinsame zu den klinischen Veränderungen führende Pathomechanismus dieser Läsionen ist eine Einschränkung der longitudinalen Bewegungsfreiheit des Rückenmarks, insbesondere des Conus medullaris, was aufgrund der biophysikalischen Eigenschaften des Marks eine lokale Ischämie im Rückenmark zur Folge hat. Zur bildgebenden Diagnostik eignet sich in erster Linie die lumbosakrale Magnetresonanztomographie. Die Behandlung besteht in einer Wiederherstellung der Bewegungsfreiheit des Conus medullaris mittels mikrochirurgischer Durchtrennung des Filum terminale unter Monitoring der sakralen Nervenwurzeln. Die Aussichten, einer Verschlechterung des Zustands bei geringem Komplikationsrisiko Einhalt zu gebieten, sind gut, zusätzlich wird immerhin in etwas weniger als der Hälfte der Fälle eine Besserung erreicht. Allen Patienten, die mehr als nur kutane Dysraphiezeichen aufweisen und besonders denjenigen mit progredienter Symptomatik sollte eine spezialisierte chirurgische Behandlung angeboten werden.

    Notes: Summary  148 elderly patients, aged 70 years or more, diagnosed as having lumbar spinal stenosis, were operated upon at our institution during 1983 to 1995. Totally 161 operative procedures were performed. We analysed retrospectively the results of the surgical treatment.  The most frequently performed procedure was multisegmental laminectomy, in 32% interlaminar fenestration and laminotomy were done. In 9 cases fusion was indicated, two of them being secondary operations. The mean hospital stay was 11 days. The morbidity was 6%, and there was one fatality (0.6%). The outcome was determined according to the six-grade classification proposed by Pappas and Sonntag [25]. Overall, in 91% of cases satisfactory-to-excellent result could be achieved.  We conclude, that in elderly patients with symptomatic lumbar spinal stenosis, with no evidence of instability, decompressive surgery without stabilisation can be done in the majority of patients with low morbidity and high expectation of clinical improvement.

    Notes: Summary 50 adult supratentorial low-grade astrocytomas operated upon between 1984 and 1988 were analysed retrospectively with respect to postoperative condition and progression-free survival. Pilocytic lesions were excluded. In 32 instances the tumour was macroscopically completely removed and partially in 4. In 14 cases a stereotactic biopsy was performed only. 10 patients received postoperative radiotherapy with 55 to 65 Gy. 1 patient died perioperatively from pulmonary embolism. 39 patients could resume their previous activities after discharge from the hospital, 10 were significantly disabled by neurological deficit, reduced neuropsychological performance or medically intractable epilepsy. Postoperatively, most patients required continuous anti-epileptic medication. 10 recurrences or tumour progressions of incompletely removed or merely biopsied lesions were observed within the mean follow-up period of 22 months. All recurrences after gross total removal, that were reoperated, had progressed to a malignant glioma. Of the prognostic tumour characteristics analysed, a histologically well-delineated tumour demarcation was most clearly associated with a favourable prognosis. Concerning treatment modalities, gross total resection was associated with a favourable prognosis. Radiotherapy was associated with an unfavourable outcome but this is probably due to selection of otherwise unfavourable cases.
