Evaluation Of Spino-pelvic Parameters Acording To Intraoperative Position In Spine Lumbosacral Arthrodesis [avaliação Dos Parâmetros Espinopélvicos Pelo Posicionamento Intra-operat ório Na Artrodese De Coluna Lom Bo-sacra]

Objective: To evaluate the relationship between spino-pelvic preoperative, intraoperative, and postoperative parameters and the influence of surgical positioning with these values. Methods: This retrospective study evaluates radiographs pre-, intra-and postoperative patients who underwent arthrodesis of the lumbosacral spine. Results: Of the 16 patients evaluated a decreased sacral slope between the pre-and postoperative was observed, with a direct influence on the values of lumbar lordosis, with a consequent angular reduction. Conclusion: There is a variation in sacral inclination as a function of position on the operating table, mainly between the pre-and intraoperative position, during fusion surgery of the lumbosacral spine, and the sacral slope is directly responsible for the change in lumbar lordosis.123228231Roussouly, P., Pinheiro-Franco, J.L., Biomechanical analysis of the spino-pelvic organization and adaptation in pathology (2011) Eur Spine J, 20 (SUPPL. 5), pp. 609-618Dubousset, J., Charpak, G., Dorion, I., Skalli, W., Lavaste, F., Deguise, J., Le système eos nouvelle imagerie osteo- articulaire basse dose en position debout (2005) Memoires de Academie Nationale de Chirurgie, 4 (4), pp. 22-27Davis, H., Increasing rates of cervical and lumbar spine surgery in the united states, 1979-1990 (1994) Spine (Phila Pa 1976), 19 (10), pp. 1117-1123Hennemann, A.S., Antoneli, P.H., Oliveira, G.C., Incidência pélvica: um parâmetro fundamental para definição do equilíbrio sagital da coluna vertebral (2012) Coluna/Columna, 11 (3), pp. 237-239Stagnara, P., De Mauroy, J.C., Dran, G., Gonon, G.P., Costanzo, G., Dimnet, J., Reciprocal angulation of vertebral bodies in a sagittal plane: Approach to references for the evaluation of kyphosis and lordosis (1982) Spine (Phila Pa 1976), 7 (4), pp. 335-342Legaye, J., Duval-Beaupère, G., Hecquet, J., Marty, C., Pelvic incidence: A fundamental pelvic parameter for three-dimensional regulation of spinal sagittal curves (1998) Eur Spine J, 7 (2), pp. 99-103During, J., Goudfrooij, H., Keessen, W., Beeker, T.W., Crowe, A., Toward standards for posture postural characteristics of the lower back system in normal and pathologic conditions (1985) Spine (Phila Pa 1976), 10 (1), pp. 83-87Le Huec, J.C., Aunoble, S., Philippe, L., Nicolas, P., Pelvic parameters: Origin and significance (2011) Eur Spine J, 20 (SUPPL. 5), pp. 564-571Vialle, R., Levassor, N., Rillardon, L., Templier, A., Skalli, W., Guigui, P., Radiographic analysis of the sagittal alignment and balance of the spine in asymptomatic subjects (2005) J Bone Joint Surg Am, 87 (2), pp. 260-267Boulay, C., Tardieu, C., Hecquet, J., Benaim, C., Mitulescu, A., Marty, C., Anatomical reliability of two fundamental radiological and clinical pelvic parameters: Incidence and thickness (2005) Eur J Orthop Surg Traumatol, 15, pp. 197-204Bourghli, A., Aunoble, S., Reebye, O., Le Huec, J.C., Correlation of clinical outcome and spinopelvic sagittal alignment after surgical treatment of low-grade isthmic spondylolisthesis (2011) Eur Spine J, 20 (SUPPL. 5), pp. 663-668Neter, J., Kutner, M.H., Nachtsheim, C.J., Wasserman, W., (1996) Applied Linear Statistical Models, , 4th ed.
