Author experience and literature review. ⋯ Segmental pedicle screw fixation coupled with one of four posterior osteotomy/resection techniques can be used to address most sagittal plain deformities. Careful application of these techniques is important. Smith-Petersen and Ponte osteotomies are most appropriate for long sweeping deformities with mobile anterior columns. Pedicle subtraction osteotomies and vertebral column resections are most appropriate for fixed, sharply angulated spinal deformities. The successful application of these techniques is dependent on accurate preoperative evaluation of the structural properties of the kyphosis and meticulous execution of the surgical technique.

Review article. ⋯ An appreciation of both the coronal and sagittal plane components of spinal deformity is mandatory to achieve optimal results with surgical stabilization of adult scoliosis.

Author experience and literature review. ⋯ As the magnitude of resection increases, the ability to correct deformity improves, but also the risk of complication increases. Therein, an understanding of potential applications and complications is helpful.

Review Case Reports
Lumbosacral nerve root anomaly associated with spondylolisthesis in an adolescent: a case report and review of the literature.
Case report. ⋯ This case emphasizes the need to consider the presence of lumbosacral nerve root anomalies in cases in which neurologic findings exceed what would be anticipated. Preoperative identification of these anomalies allows for their existence to be considered in the surgical plan.
