Importancia de la estática del raquis lumbar y pelvis en la estenosis degenerativa del canal raquídeo lumbar

The objective of this paper is to examine some parameters of the static of the lumbosacral spine in 50 patients with degenerative stenose of lumbar spine, and in a control groupe of 31 subjects without antecedents of spine pathology, and to evaluate the differences between both groups. We studied by means of simple radiology: the discal height, the lumbar lordosis, the index of Taillard, the discal angle L5-S1, the level of the iliacs crests, and the angle of Cauchoix. The angel of Ferguson was significantly smaller in the group of patients that in that of the controls. The lordosis didn't vary significantly between groups, but it was significantly different if it was observed in function of the number of narrowed levels. In the control group, the stable pelvic despositions (where the crests iliacas coincides with fourth lumbar vertebra) prevailed in a significant way-
