Atypical forms of spinal tuberculosis

Summary Twenty-three patients with atypical forms of spinal tuberculosis treated between 1975 and 1985, are described.All presented with signs and symptoms of compression of the spinal cord or cauda equina, ranging from paraesthesiae and increasing weakness of extremities to paraplegia and loss of sphincter control. None of them showed visible or palpable spinal deformity nor the typical radiographic appearance of destruction of the intervertebral disc and the two adjoining vertebral bodies. These atypical forms constituted about 12 percent of all the cases of spinal tuberculosis seen (a total of 190 cases); and fell into three well-defined groups: those with the involvement of neural arch only; those with the inolvement of a single vertebral body; and, those without bony involvement. The correct surgical approach in these groups was found to be different: spinal cord compression caused by the tuberculous disease of the neural arch was best treated by laminectomy; whereas single vertebral body disease required an anterior or anterolateral approach. Spinal computerized tomography was helpful in defining the extent of disease and planning the surgical approach. Histological confirmation of tuberculosis was obtained in all the cases and acid fast bacilli (A.F.B.) were found in, and cultured from, the biopsy specimens of 18 cases.

Incidence and significance of findings on spinal MRIs in a paediatric population with spinal column complaints

PurposeWe sought to identify correlations between working diagnosis, surgeon indication for obtaining spinal MRI and positive MRI findings in paediatric patients presenting with spinal disorders or complaints.MethodsSurgeons recorded their primary indication for ordering a spinal MRI in 385 consecutive patients. We compared radiologist-reported positive MRI findings with surgeon response, indication, working diagnosis and patient demographics.ResultsThe most common surgeon-stated indications were pain (70) and coronal curve characteristics (63). Radiologists reported 137 (36%) normal and 248 (64%) abnormal MRIs. In total, 58% of abnormal reports (145) did not elicit a therapeutic or investigative response, which we characterized as ‘clinically inconsequential’. In all, 42 of 268 (16%) presumed idiopathic scoliosis patients had intradural pathology noted on MRI.Younger age (10.3 years versus 12.0 years) was the only significant demographic difference between patients with or without intradural pathology. Surgeon indication ‘curve magnitude at presentation’ was associated with intradural abnormality identification. However, average Cobb angles between patients with or without an intradural abnormality was not significantly different (39° versus 37°, respectively). Back pain without neurological signs or symptoms was a negative predictor of intradural pathology.ConclusionRadiologists reported a high frequency of abnormalities on MRI (64%), but 58% of those were deemed clinically inconsequential. Patients with MRI abnormalities were two years’ younger than those with a normal or inconsequential MRI. ‘Curve magnitude at presentation’ in presumed idiopathic scoliosis patients was the only predictor of intrathecal pathology. ‘Pain’ was the only indication significantly associated with clinically inconsequential findings on MRI.Level of evidence:III     

MR-imaging of chronic spinal cord injury. Association with neurologic function

Twenty-two para- and tetraplegic patients with chronic spinal cord injuries were examined with magnetic resonance imaging (MRI). The clinical course in the entire rehabilitation period was recorded and an attempt was made to associate the functional status of the patients with the morphologic findings on MRI. Small and large spinal cord cysts and syringomyelia, cord atrophy, and spinal stenosis were found. Additionally, in a number of patients regions of increased signal intensity within the cord, interpreted as myelomalacia, and obliteration of the intradural extramedullary space, interpreted as arachnopathy, were noted. The large number (13/22) of cystic lesions in our patients was unexpected. It was in contrast to the rate reported in autopsy studies of paraplegics which note only few cysts. Whereas a direct association of morphologic findings with neurologic symptoms and the clinical course was difficult, it was found that patients with large cysts and spinal cord atrophy generally showed no tendency to improve in spite of the measures taken during the rehabilitation period. It is difficult to decide whether the initial trauma with cord hemorrhage is limiting the chance of neurological improvement or if a sequence of events leading from hemorrhage to gliosis and cystic necrosis is the determining factor.     

Somatosensory evoked potential

Summary Somatosensory evoked potentials (SSEPs) have been used to help minimize neurologic morbidity during spinal surgery. While this is a sensory test it has been used as an inference of motor function. The failure to always achieve the latter goal has resulted in some pessimism regarding the value of this test. In this series of 161 operations in 150 patients, it was demonstrated that SSEPs were recordable under anesthesia in 87% of patients. Of these patients, 12% had their spinal surgery interrupted due to significant neurophysiologic changes; of these patients, 18% had new neurologic deficits postoperatively. There were no cases with new neurologic deficits who had no changes in their SSEPs. It was concluded that SSEP monitoring may be helpful in identifying potentially neurologically threatening surgical maneuvers in a significant number of patients.

Flow characteristics of Luer and non‐Luer spinal needles

We investigated the flow rates of 25‐G and 27‐G spinal needles, of 90‐mm and 120‐mm lengths, from Vygon, BD, B. Braun and Pajunk; the needles had either a Luer connector, or a Surety^® or UniVia^® non‐Luer connector. We used a bench‐top model of entering the spinal space, pressurised to 35 cmH₂O to simulate cerebrospinal fluid pressure in the sitting position. We examined the time to first appearance of simulated cerebrospinal fluid in the needle hub, as well as the amount of fluid collected over 120 s after the needle was introduced. The mean (SD) times to first appearance of fluid in the needle hub of Luer spinal needles varied from 0.36 (0.22) s for the 25‐G 90‐mm BD to 3.14 (0.72) s for the 27‐G 120‐mm B. Braun, and in the non‐Luer spinal needles from 0.22 (0.17) s for the 25‐G 90‐mm B. Braun to 2.99 (0.71) s for the 27‐G 120‐mm Pajunk. There was a significant difference in the time to first appearance of fluid in the needle hub between Luer and non‐Luer needles of the same type for seven of 14 comparisons made, of which four showed slower appearance of fluid in the non‐Luer version. In some of these cases, the time to appearance of fluid was nearly twice as long with the non‐Luer counterpart. The mean (SD) weight of fluid collected in 120 s using the Luer spinal needles varied from 0.21 (0.05) g for the 27‐G 120‐mm Pajunk to 1.21 (0.18) g for the 25‐G 90‐mm Vygon, and using the non‐Luer spinal needles from 0.25 (0.05) g for the 27‐G 120‐mm Pajunk to 1.55 (0.05) g for the 25‐G 90‐mm B. Braun. All of the needle types showed a greater weight of fluid collected using the non‐Luer compared with the Luer version, with six of the 14 needle types showing a significant difference. Significant variations in flow were also seen between the same needle type from different manufacturers. We conclude that changing from Luer to non‐Luer versions of spinal needles does not merely change the hub design and connection, but may introduce important differences in function.
