Treatment of Spondylolisthesis in Children and Adolescents / 대한척추외과학회지

ABSTRACT

In spondylolisthesis of children and adolescents, the main cause of deformity is not the percentage of slippage, but the lumbosacral kyposis. Slip angle is of significant help in determining the lumbosacral kyphosis and the likelihood of further progression of slippage. Reduction has been considered unnecessary by many authors because of the reliability of in situ fusion. However, in severe cases, posterior arthrodesis is stressed in distraction and seems hardly able to stabilize the instability. An optimal reduction would place L4 parallel or lordotic in relation to the sacrum. Several unresolved questions remain How should the reduction be achieved? Should the reduction be stabilized by internal fixation systems? What kind of fixation device provides the best stabilization?
