Cette étude rétrospective analyse les complications rachidiennes de la drépanocytose observées de 1982 à 1991. Trente-quatre patients ont été traités dans les services d'orthopédie et de neuro-chirurgie de l'Hôpital universitaire King Fahd à Al Khobar. Il s'agissait de 21 hommes et de 13 femmes, âǵes en moyenne de 17.4 ans, avec des extrêmes de 4 à 28 ans. Des modifications structurales du corps vertébral liées à l'hyperplasie médullaire sont survenues chez 44% des patients. Des nécroses avasculaires responsables d'un effondrement du corps vertébral ont été observéees chez 9 patients (26.5%). La spondylite infectieuse, qui constitue la complication la plus grave, a concerné 8 patients (23.5%), dont la plupart ont bénéficié d'une décompression antérolatérale et de greffes osseuses. Nous pensons que le rachis est souvent atteint au cours de la drépanocytose et qu'un traitement agressif et une étroite surveillance sont nécessaires pour éviter des séquelles majeures.Notes: Summary Bone changes in sickle cell disease occur due to marrow hyperplasia, tissue ischaemia and infarction due to vaso-occlusion. Between 1982 and 1991 thirty four patients were treated in the Orthopaedic and Neurosurgery Departments of the Kind Fahd University Hospital, Al-Khobar, with spinal complications due to sickle cell disease. There were 21 males and 13 females aged between 4 and 28 years (mean 17.4 years). Structural changes in the vertebral bodies due to marrow hyperplasia occurred in 44% of the patients. Avascular necrosis leading to collapse of the vertebral bodies was seen in 9 (27%) patients. Infective spondylitis was the most serious complication seen in 8 (24%) patients; the majority needed anterolateral decompression and bone grafting. The spine is often affected in sickle cell disease and aggressive treatment with close follow-up is required to avoid disabling complications.Type of Medium: Electronic ResourceURL: -

ISSN: 1434-453XSource: Springer Online Journal Archives 1860-2000Topics: Architecture, Civil Engineering, SurveyingGeosciencesNotes: Summary The jointed roof in laminated rock mass may be capable of self-support and sustaining transverse load and can be analysed by the voussoir beam notation. There are three main failure modes of a voussoir beam structure: crushing in the high stress areas, buckling without localised material failure and shear sliding along the joints. Previous studies on the voussoir beam have concentrated on the crushing failure mode, assuming that the voussoir beam would not fail by shear sliding prior to reaching its crushing strength. However, the possibility exists that the voussoir beam may collapse by shear sliding along the joints with a strength much lower than that predicted by the estimation method for crushing failure, depending upon the joint properties. Hence the stability analysis of a jointed roof without considering the shear sliding failure may lead to disastrous consequences. In this paper a numerical and experimental study has been carried out to analyse the shear sliding failure of voussoir beams containing vertical and inclined joints with one or more mid joints. Equations for verification of shear sliding are proposed and effects of the voussoir beam geometry and material properties on the shear sliding failure are also discussed.Type of Medium: Electronic ResourceURL:
