    Notes: Abstract The case of a 21/2-year-old boy with diffuse cystic angiomatosis of bone is presented. No evidence of visceral involvement was recorded. The clinical, radiographic and histologic findings during the course of the disease process are discussed. At the age of 15 years the patient died of neurologic alterations developed due to massive osteolysis and collapse of the cervical spine, and severe dyspnoea, secondary to persistent bilateral pleural effusions.

    Pedicle screw fixation in spinal disorders: A European view (1997)

    Notes: Abstract Continuing controversy over the use of pedicular fixation in the United States is promoted by the lack of governmental approval for the marketing of these devices due to safety and efficacy concerns. These implants have meanwhile become an invaluable part of spinal instrumentation in Europe. With regard to the North American view, there is a lack of comprehensive reviews that consider the historical evolution of pedicle screw systems, the rationales for their application, and the clinical outcome from a European perspective. This literature review suggests that pedicular fixation is a relatively safe procedure and is not associated with a significantly higher complication risk than non-pedicular instrumentation. Pedicle screw fixation provides short, rigid segmental stabilization that allows preservation of motion segments and stabilization of the spine in the absence of intact posterior elements, which is not possible with non-pedicular instrumentation. Fusion rates and clinical outcome in the treatment of thoracolumbar fractures appear to be superior to that achieved using other forms of treatment. For the correction of spinal deformity (i.e., scoliosis, kyphosis, spondylolisthesis, tumor), pedicular fixation provides the theoretical benefit of rigid segmental fixation and of facilitated deformity correction by a posterior approach, but the clinical relevance so far remains unknown. In low-back pain disorders, a literature analysis of 5,600 cases of lumbar fusion with different techniques reveals a trend that pedicle screw fixation enhances the fusion rate but not clinical outcome. The most striking finding in the literature is the large range in the radiological and clinical results. For every single fusion technique poor and excellent results have been described. This review argues that European spine surgeons should begin to back up the evident benefits of pedicle screw systems for specific spinal disorders by controlled prospective clinical trials. This may prevent forthcoming medical licensing authorities from restricting the use of pedicle screw devices and dictating the practice of spinal surgery in Europe in the near future.

    Segmental patterns of rib-vertebra angles in chest radiographs of children: Changes related to rib level, age, sex, side and significance for scoliosis (1992)

    Notes: Rib-vertebra angles (RVAs) were measured (T1-12) on the chest radiographs of 412 children aged 0-17 years attending the hospital with minimal disorders or diseases (boys 193, girls 219). A new method for measuring RVAs is used and the asymmetry of rib-vertebra angles is calculated as rib-vertebra angle differences (RVADs). The data are analysed in three age groups - infancy, childhood, and puberty, after the classification of Karlberg (1989).The findings show the following:(1) RVAs decrease from T1-12, especially so between (T8 and T12.2) Between infancy and childhood, RVAs of the upper ribs incrase, more so in boys than girls. (3) Between childhood and adolescence there is a further elevation of ribs, involving more ribs in boy than girls (boy T1-10, girls T1-8). (4) Between infancy and childhood, the lower ribs droop more in girls than boys (boys T9-10/12, girls T7/8-12). There is no change in the RVAs of the lower ribs between childhood and puberty in either boys or girls. (5) The hypothesis is suggested that RVAs are influenced by the central nervous system through its influence on trunk muscle activity. (6) Ribvertebra angle asymmetries (or differences, RVADs) are related to age and sex; their pattern reflects the common age, sex, and laterality patterns of idiopathic scoliosis. Extremes of such asymmetries may be an etiological factor for both infantile and adolescent idiopathic scoliosis. © 1992 Wiley-Liss, Inc.

    Segmental patterns of sagittal spinal curvatures in children screened for scoliosis: Kyphotic angulation at the thoracolumbar region and the mortice joint (1992)

    Notes: This paper reports a segmental analysis of the lateral spinal radiographs of 37 children referred to hospital in a school screening study of 4,890 school children aged 12-13 years. On each lateral radiograph a line was drawn along the posterior surface of each vertebral body from T5-L5 and the angle of this line from the vertical was recorded.After measuring the scoliosis curve (Cobb) angle and using conventional criteria for diagnosis, three groups of patients are defined, namely, 1) a control group (average scoliosis curve angle (Cobb) of 5°, n = 14), 2) a group with lumbar curves (average Cobb angle 21°, n = 7), and 3) a group with thoracic curves (average Cobb angle 19 degrees, n = 10). Individual lateral spinal profiles are also analyzed.The findings show: (1) In the control group, there are different degrees of vertical backward tilt (declivity) from T7-L3, with a maximum tilt at T12 (mean 26°). The most vertical vertebrae are T6 and L4, with forward tilting (proclivity) at each of (T5 and L5.2) In the lumbar curve group, the segmental sagittal tilt is not significantly different from that in the control group. The mean declivity at T12 is 25°. (3) In the thoracic curve group, the segmental sagittal tilt is significantly less than that in the control group at each of T10-L1. The mean declivity at T12 is 17°. A more vertical T12 is associated with a larger Cobb angle. (4) The individual sagittal spinal profiles of the thoracic curve group (but no other group) show lordosis in the region of the lateral spinal curve (scoliosis) and a kyphotic angulation at an average of three vertebrae below the apical vertebrae of the scoliosis curve. (5) It is suggested that as a thoracic lordoscoliosis develops, the appearance of a kyphotic angulation in the thoracolumbar and upper lumbar spine is determined by the compressibility of each disc in relation to the length of the articular processes at the corresponding level. Where the combination of disc weakness to facet length is most adverse, forward flexion occurs, as in a spinal fracture, to produce the kyphotic angulation. © 1992 Wiley-Liss, Inc.
