Osteotomies may be life saving procedures for patients with rigid severe spinal deformity. Several different types of osteotomies have been defined by several authors. To correct and provide a balanced spine with reasonable amount of correction is the ultimate goal in deformity correction by osteotomies. ⋯ VCR provides the greatest amount of correction among other osteotomy types with complete resection of one or more vertebral segments with posterior elements and entire vertebral body including adjacent discs. It is also important to understand sagittal imbalance and the surgeon must consider global spino-pelvic alignment for satisfactory long-term results. Vertebral osteotomies are technically challenging but effective procedures for the correction of severe adult deformity and should be performed by experienced surgeons to prevent catastrophic complications.

The diagnostic assessment and prognostic value of the posterior ligamentous complex (PLC) remains a controversial topic in the management of patients with thoracolumbar spinal injury. The purpose of this review was to critically appraise the literature and present an overview of the: (1) precision, (2) accuracy, and (3) validity of detecting PLC injuries in patients with thoracic and lumbar spine trauma. ⋯ A wide variety of methods have been applied in the evaluation of precision and accuracy of PLC injury detection, leaving spinal surgeons with a multitude of variable results. There is scant clinical evidence demonstrating the true prognostic value of detected PLC injuries in patients with thoracic and lumbar spine injuries. We recommend the conduct of longitudinal clinical follow-up studies on those cases assessed for precision and/or accuracy of PLC injuries.

Review Case Reports
Solitary spinal epidural cavernous angioma: report of nine surgically treated cases and review of the literature.
We intend to report the largest series of spinal epidural cavernomas (SEC), discuss their clinical features, imaging characteristics, surgical findings, outcome analysis and compare them with similar reports in the literature. ⋯ SEC is hard to be differentiated from other epidural spinal lesions before intervention but should be considered in the list of differential diagnosis regarding its favorable outcome.

Obtaining a fusion, especially to the sacrum for adult deformity correction remains a challenge. Prior to modern fixation techniques, the reported fusion rates for adult scoliotic deformities were low. However sacropelvic fixation techniques for adult deformity continue to evolve. As a result, modern day pelvic fixation techniques have improved fusion rates at the base of long constructs. The purpose of this article is to discuss the history, indications, and modern fixation techniques for pelvic fixation in the surgical management of adult scoliosis patients. ⋯ There is growing evidence that pelvic fixation may become the standard for obtaining long fusions in adult scoliosis. Although technically challenging, in selected cases the use of four pelvic screws and/or four rods across the lumbosacral pelvis can help address pseudarthroses, implant breakage, and screw pullout secondary to osteoporosis. Ultimately, indications and techniques should be individualized to the patient and based on surgeon preference and experience.
