title: [Spondylolisthesis with severe displacement in children and adolescents Results of 12 cases of posterior reduction fixation].
abstract: The aim of this study was the analysis of 12 cases showing a L5-S1 spondylolisthesis of a shift superior to 50%. The surgery performed on those 12 children and teenagers was Roy Camille's technical procedure that is reduction and fixation with posterior plates and postero-lateral grafting The criteria of the study and technique used are first recalled. The result's analysis show the quality of the reduction and the restoration of the lumbo-pelvic statics. The postero-lateral arthrodesis appears to the authors as sufficient to guarantee the result's stability. In cases of associated radicular impairment, great care must be taken as far as the reduction is concerned. The root must be controlled during the surgical procedure especially if there is a real sciatic before surgery. The technic appears to the authors as the best among all those they may have used for the treatment of the spondylolisthesis with an important shift, apart from the spondyloptosis. Internal fixation devices of a smaller size would be necessary for a small child.
