Minimally invasive anterior column realignment for the treatment of adult spinal deformity: A review of the literature

Surgical treatment of adult spine deformity requires correction in multiple planes. Currently employed open and minimally invasive techniques and instrumentation allow for robust rotational and coronal-plane correction. However, large sagittal deformities frequently require vertebral osteotomies, which can increase morbidity and complications, particularly in an elderly population. Anterior column realignment has emerged as a technique that can provide significant sagittal plane correction through a minimally invasive approach. We will provide an overview of this procedure, technical challenges, risks, outcomes, and review the recent literature on anterior column realignment for the treatment of adult spine deformity.
