Lumbosacral spondylolisthesis, when it is associated with scoliosis, presents special problems which require special consideration in management. Lumbosacral spondylosisthesis associated with a major thoracic curve, presents two separate problems. Treatment of the lumbosacral spondylolisthesis depends upon the severity of the lesion and symptoms. The thoracic curve is treated as required, depending upon the severity of the scoliosis and the stage of spinal maturation. Lumbosacral spondylolisthesis associated with a thoracolumbar or lumbar curve requires treatment of the curves above, along with the spondylolisthesis. Do not fuse the lumbosacral joint in an uncorrected position.
