    Notes: Summary The purpose of this study was to evaluate whether wide surgical exposures result in poorer outcome of lumbar disc surgery compared to smaller traditional exposures. The aim was also to assess if a dural tear has any impact on the postoperative clinical outcome. One hundred and twenty-two patients (56 women and 66 men, mean age 40.8 years) with herniated intervertebral lumbar disc and no previous back surgery, were included. Postoperatively they were grouped according to surgery as follows: surgery on one vs. two herniated discs (106 vs. 16 patients), partial vs. full laminectomy (93 vs. 29 patients), and the occurrence or not of a dural rent (8 vs. 114 patients). The outcome of surgery was evaluated one year postoperatively mainly by a composite clinical overall score (COS) and by its separate elements, which were: pain intensity in the lower-back or leg (VAS), neurological and clinical examination, functional capacity (Oswestry), and the need for analgesics. The results of the statistical regression analyses did not reveal significant differences in the postoperative outcome scores in the various groups of patients. The groups were comparable; no significant differences were seen in the pre-operative clinical overall scores.

    Notes: Summary Intracranial epidural pressure (EDP) was continuously recorded in two patients with traumatic pneumocephalus. In an experimental study EDP and nasal air pressure (NAP) were recorded in other neurosurgical patients during coughing, sneezing, straining, and blowing the nose. In traumatic pneumocephalus periods of clinical deterioration—not related to infection—were found to be caused by intracranial hypertension during periods of no CSF leakage. The EDP reached levels of about 100 mm Hg. Coughing, sneezing, and straining can accelerate the exchange of CSF with air, but cannot in itself cause lasting intracranial hypertension. Blowing the nose, which is similar to a Valsalva's manoeuvre, can accelerate the exchange of CSF with air, and—with the fistula acting as a one way valve—increase the EDP level up to a maximum of about 40 mm Hg. However, the main mechanism behind the intracranial hypertension is assumed to be intracranial air causing impaired drainage of CSF either by simple mechanical blockage or by damping the forces behind the CSF dynamics. The term pneumo-hydrocephalus is descriptive of this condition. During this state of intracranial hypertension dynamic variations in intracranial pressure attributed to cerebral vasomotor instability were observed.

    Notes: Summary Queckenstedt's test was carried out in 15 patients with marked rheumatoid atlanto-axial luxation. The test was done when moving the neck stepwise between flexion and extension, and with the patient in both lateral and sitting positions. The test performed in the sitting position was termed the functional Queckenstedt's test. The flexed position of the neck and the sitting body position, either alone or in combination, were factors contributing to a manometric block. Six more block phenomena were recorded in the sitting compared with the lateral position. As the sensitivity of the test seemed unaffected by body position, this indicated an increased atlanto-axial luxation in the sitting position. This applied to the neutral as well as the flexed position of the neck. There was a fairly good correlation between neurological symptoms and signs and the functional Queckenstedt's test. The use of the test as an aid supplementary to the clinical and roentgenological findings when deciding on the treatment of patients with rheumatoid atlanto-axial luxation is outlined.

    Notes: Abstract Flexion-distraction injuries of the spine are reported after traffic accidents in individuals wearing only lap seatbelts. We examine here this type of injury in one child and two adolescents who all were seated in the rear seat of cars involved in traffic accidents. All of the children were wearing regular three-point safety belts not adjusted to children. They were all treated surgically. Two of the patients had no neurological impairment, while one patient suffered persistent complete paraplegia. In two patients intra-abdominal lesions required surgery. Flexion-distraction injuries in individuals with an immature skeleton, wearing standard three-point safety belts, have not been reported in the literature. The pathomechanism of the lesion in the lower spine may well involve damage to the intestines, particularly at the junction between the mobile intra-abdominal and the fixed retroperitoneal part of the gut. Reduction and stable fixation preserve the anatomy of the lower spine, while unstable fixation methods do not secure reduction sufficiently to allow early mobilisation.

    Notes: Summary Acute, painful torticollis in a child is not uncommon. When no local changes can explain the disease, atlanto-axial rotary fixation should be considered. The position of the head is typical but the roentgenological diagnosis is difficult, and as early treatment is mandatory, it should be initiated even if the roentgenogram is “normal”. We present a review of nine patients.

    Notes: Summary A pressure transducer with a disposable, presterilized fluid chamber was developed to increase the safety margin when recording cerebrospinal fluid (CSF) pressure. With this system the fluid compartment is completely separated from the transducer proper, reducing electrical hazard and the risk of infection. The operational range is form — 20 mm Hg to 300 mm Hg with good static accuracy. The transducer with stopcocks has a flat frequency response of up to 75 Hz, showing that the two-part principle is compatible with good dynamic performance. The transducer system was easy to handle and well suited to the recording of ventricular fluid pressure, detection of spinal subarachnoid block, the investigation of CSF absorptive capacity, as well as blood pressure recording. When the transducer was connected to standard disposable stopcocks, needles, and tubing as for these recordings, the dynamic accuracy of the whole apparatus was satisfactory for analysis of the pulsatile wave-form. A total of 185 CSF pressure recordings was performed without complication.
