Instrumentation Techniques Including Sacral and Pelvic Fixation
Lumbar degenerative scoliosis and anterior imbalance represent common spinal deformities in the aging population. Surgical treatment might be considered if conservative treatment remains inefficient on low back and leg pain and in progressive trunk imbalance. Adult spinal deformity associated with imbalance has an impact on health-related quality of life (QoL). Correction of sagittal imbalance can be performed with surgical techniques such as Smith-Petersen or Ponte osteotomies in deformities where the intersomatic space remains mobile, whereas a pedicle subtraction osteotomy (PSO) is usually indicated in severe rigid deformities.
