This issue of the Neurosurgery Clinics, Guest Edited by Drs. Jian, Ames, and Shaffrey, presents updates and state-of-the-art approaches to spinal deformity surgery. Spine surgery is a timely topics amongst neurosurgeons, and one that is continually evolving. Articles in this issue include Radiographic and Clinical Evaluation of Adult Spinal Deformity; Use of Surgimap in Osteotomy Planning, Correction Calculation, and Reciprocal Changes; Adolescent Scoliosis Classification and Treatment; Osteotomy for Rigid Deformity; Coronal Realignment, Reduction Techniques, and Complication Avoidance; Cervical Deformity; High Grade Sponylolisthesis; Proximal Junctional Kyphosis; and The Role of Minimally Invasive Techniques in the Treatment of Adult Spinal Deformity.

In this issue of Neurosurgery Clinics, guest editors Drs. Sigurd Berven and Praveen V. Mummaneni bring their considerable expertise to the topic of Spinal Deformity Update. Top experts in the field discuss key topics surrounding abnormal curves in the spine, covering preoperative planning, open surgical approaches, minimally invasive surgical approaches, postoperative care; and more. Contains 19 relevant, practice-oriented topics including preoperative optimization: risk factors for perioperative complications and preoperative modification; when to do less with adult deformity surgery: fusion of the fractional curve vs. the entire deformity; robotic assisted surgery and navigation in deformity surgery; complications and avoidance in adult deformity surgery; and more. Provides in-depth clinical reviews on spinal deformities, offering actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.
